If it's same as Yaris, it's 475ml oil in diff. Few solutions or mix for even better results: wrap exhaust, rear diff vent (Airtec, HRNSHN...), Hel's diff oil cooler, Cusco rear diff cover (750ml oil)
Its not really diff overheating - it's the clutch pack in front of it - and that oil is not shared between the diff and the clutch pack unit. Clutch pack unit is a sealed unit.
Heat wrap the exhaust near the rear diff. I think for the Yaris there’s an aftermarket vent that directs air to the diff. Seems like you guys are well informed on the issue and on top of it. Good video as always!
That's exactly the issue people over seas complain about with the gr yaris. Some people seam to say putting it in "track mode" helps but it can still happen. Hope you guys figure something out that works
We are going to try some cooling tricks and see how it goes. The point of this build is to figure all these little things out for others to enjoy their cars more!
My oil temp went to 135°C on a 19° day - HEL oil cooler fixed that. With the rear diff - can wrap the exhaust that snakes around it. There are also options for the cooling scoops. Not sure if GR Corolla weight plays a bigger part - Yaris is sub 1300kg, so never had a diff overheat and I drove it at Phillip Island racetrack with air temps above 40°
@Just Driven I always drive 50:50. Never had a diff overheat issues. I must have done 8 or 9 track days by now. My Yaris does have front and rear torsens. Not sure what your GRC has. Enjoy 👍
Of course! We are already cracking away at the cooling issues we had at the track and getting an exhaust for it. It sounded so wimpy compared to the other cars on track!
If you had lsd’s, forged wheels and ps4s tyres I believe the better traction/less wheel spin would help reduce your overheat issue with the center clutch pack and rear diff.
you tracked on the 0w20 engine oil? how were the temps? oil pressure? what tire pressure did you guys end up settling in? thanks 😁 I'll be at sow cw Sunday the 19th. but I can't wait to go to BRP
@@JustDriven was there an update video on the temps? bummer the GRC didnt make it out to BRP last weekend, i saw the ISC and they werent happy with the newly valved dampers...
Not sure what mode you were on but try track mode, 50/50 split should not let the clutches slip as much and reduce the heat put in the system. Suzuki had a similar system on the SX4 and for their WRC drivetrain the just locked it to 50/50 and had no overheating issues.
It's a common issue with the system. The GRY has had the issue in different modes and someone overheated their GRC in 50/50. System always slips causing heat.
@MrBenstero The rear diff is over driven (different ratio to front diff) which enables the car to shift torque front to rear. The clutches will always be slipping while power is being sent to the rear wheels. If it locked as you put it, the rear wheels would be going faster than the front which would break the transmission. Air scoops, Cusco diff cover, exhaust wrap near the diff all help eliminate the issue 😉
Danny had made sure to try multiple modes on track to get the best times.We will see in future videos if he can shave off more time with cooling mods. Thank you everyone for sharing some possible solutions.
My friend has a GR Corolla he just passed away friend of 20 years. I drove his car to the funeral. It was a good experience and a bad experience all in one. He never got her to top speed after we did our mods. So on the way back i hit 150mph pretty quickly. It has 375 hp at the crank with out mods.
We are saddened to hear of your friend's passing. It is touching to know your connection to him through your love and passion for cars keeps you tethered to him even now. Hold on to that. Thank you for sharing and thanks for the watch!
I'm a little out of touch with more modern cars like this but wondering how do these compare in relatively stock to stock condition to older stuff like Evo 8s from way back in the day? Hope you get the issues with the clutch pack worked out, would be awesome if this can be turned into a reliable track car without too much fuss.
Man, it always sucks to see awesome cars with potential like this one be crippled by design oversights. Luckily, from reading some comments, it looks like there’s solutions to this issue. Still, a bone stock car should be able to manage itself without issue. Overheating components should only be a concern when modifying things
Thanks for your video! Also tracking the car, GR Yaris in Finland. Have installed Setrab Series 1 25 row during winter and exited to test it in few monts. TRD Cooling duct engine bottom cover and HRNS real clutch pack cooling duct installed.
Look for Syvecs awd module. The temp cutout in the factory system is way too conservative and it does suddendly shut off the awd once it reaches the critical temperature. The Syvecs module is fully programmable, can cutout at higher temperature and it does have a strategy in order to gently reduce the pressure in the system trying to contain the temp increase before switching off the system. I have it on my Yaris (heavily tuned) as well as every rally GR Yaris racing in the italian championship.
How easy is to install/program that module? It is my understanding that it comes already programmed by syvecs with the standard critical temperature setting. How difficult is to change that via the syvecs software?
Love the exchange of information in this comment section! Thank you guys. Whatever we go with we will do our best to share all the information with everyone too.
@@alfo40 If you can ask that’d be great, for me and other people out there who are interested on it. How different the car feels vs the OEM controller?
We suspect it would. In 2WD mode the car makes more power. Maybe we can get Danny to explain how the car feels more on camera. At the end of the video there is a candid moment with him and Alex talking about it.
Hey just subbed, new to the channel. You have great content and I am a big fan on the GR Corolla. I wanna get one myself at some point and you're making great detailed videos on everything you find with the car and adding new parts. Ill be sure to check out your new videos!
Very cool car and video........ but THIS SHOULD NOT HAPPEN when the car is basically stock. Toyota needs to resolve this issue not the aftermarket community. What is the point of this car if you cant enjoy it?
It's protection for the components on the car. It's a little conservative in the ways it saves parts of the car from harm. In hindsight we probably could have used it in 50/50 torque split longer to to prevent this overheating so quickly instead of the 30/70. We were chasing fastest laps and much like the last video we were surprised it couldn't take a little more abuse.
What you don’t know yet, is that there ISN’T a physical temp sensor on the rear diff. The ecu is making a calculated guess. I’m wondering what they change in the Morizo tune. 🤷♂️
@@JustDriven BTW, check out the Motive Video channel. They reviewed all the steps and hurdles they encountered tuning the GR Yaris over a year. Even the dyno issues you came across.
Nice write up. You never really know until you take it to the track. I would expect you have to change the brake fluid and maybe pads (and tires of course). I have been taking a look at these newer "track worthy" cars to possibly replace my "95 M3 as the tech has come a long way in 25+ years. I wonder if R Comps or 200tw tires will help or make worse the diff problem.
Thank you for the view and comment! The stickier tires we used in later videos did not help the diff. problem. In fact, to this day we still don't have a solution that's solved it.
We want something that works for street and track. Maybe something with a stiffer sidewall or maybe a little less sidewall. You'll have to check out what wheels and tires we picked out to see what we ended up going with.
Nice video. I'm surprised the car does not come with a tramsmission fluid cooler/radiator. My AMG Mercedes has one. Is it because of the AWD? Toyota knows these are going to be taken to the track. Does it have a engine oil cooler/radiator? That would also be good to have for thetrack.
at the end of the day it has a slip-and-grip budget AWD system. Toyota owns Torsen and puts *true* mechanical center differentials on many of their Lexus cars and SUVs. I think Toyota went with this slip AWD system for mpgs, weight, and budget reasons...
no, they went with this because this system gives you control over how much power is being sent to the rear and because this was designed for a rally car where all of this is not a problem.
Sorry. We see it is a major flaw that a car meant to be driven hard, seems can't be driven TOO hard. But we will update everyone with what we did to hopefully correct this.
We don't want to spend a ton on this car to have it hammer out some great lap times. So we started ironing this out as soon as we got back to the shop.
@Adimoolah it's not about mechanical strength, it's about thermal ECU intervention due to the exhaust heating the rear diff. Check out Motive on RUclips, they got 500HP (Yaris GR) and no mechanical failures after lots of thrashing, they have very strong components, just a big screw up with their exhaust and diff placement which is easily fixed.
Talk to the guys in Australia, Motive Video (RUclips) they have made one of the fastest gr Yaris. I'm pretty sure they ran into this and have a fix for it 👌. Just watch their Yaris build. They go through all pros and cons and what they have done to rectify certain issues. PEACE!!!
Thank you for the information. We are aware of the guys from Motive. They are doing amazing things with the GR Yaris. We are just trying to get to the route of some of the issues with owning the GR Corolla as a street car. We have some cool things coming for treatment for the cooling issues.
Laughing at all comments dissing the car for the well documented and easily fixed AWD overheat issue. Air duct and/or exhaust wrap solve this immediately. If you are adding more grip and more trackdays then a larger aftermarket rear diff oil container is ideal. The GR Yaris and Corolla are few of the best and budget options for dual purpose use (daily, weekend toy, occasional trackday) out of the box. Try taking any sports car/ hot hatcg in the next price bracket with stock rotors and pads on a trackday and see what happens.
So many people saying they would not buy this car based on this video. Uh, you weren't going to buy it anyway. Comparing it to the wrong cars and price points. Where has all the common sense gone?
Is it a MAJOR flaw, or is it a flaw on track? I’m not certain that every gr Corolla owner is going to rag doll the car around on the street. Yes, it is disappointing that the AWD system disengaged in cooler weather… but then again I’m just glad Toyota even made the damn thing 🎉
daOh we are beyond happy they made it. We love the car despite the overheating and the lack of power on the last episode. These are just forms of data for ourselves. Is it a flaw on track? Yah, the title is "Track Day | We Discover A Major Issue." It's not " Street Driving | We Discovered A Major Issue." Many tend to think we are disappointed in the car. Not once did we say we didn't love this car.
Yes, it is an issue on some other cars using clutches to redirect torque. Going 50/50 split may alleviate some of this as the clutches shouldn't be slipping.
I drive my GRY in sport mode to help combat this issue as more rear bias means less slip at the coupling. I also plan to get the syveccs AWD controller as it reverses the lock up strategy which reduced slip a lot. That said bog stock I’ve done 300km in a day on track in 35 degree heat without an issue. Try sport mode if you haven’t already!
I thought it was the other way around. Fwd only mode means the clutch pack is completely open. For track mode the clutch needs to close a bit, so you have 50:50. Sport mode is 30:70 meaning that the clutch pack needs to close even more in comparison to track mode in order to deliver more torque to the rear. Am I wrong?
when i test drove the GR i did one hard launch in 30/70 mode and it shut down the rear diff for 30 minutes because it overheated. its not exhaust heat causing it, its internal friction and too sensitive of a temperature sensor on the rear electronic clutch pack. big design flaw imo and why i prefer a pure awd system like subarus.
@@JustDriven it was a press car with about 6k miles on it. They were having plenty of issues with it for sure. But when I had my go, I did a launch just like everyone else, and boom. No more awd.
@@JustDriven I'm competing in stock class in the 86Cup, so I've got absolute minimal mods for the year. My main focus is driver development. Maybe I'll drop by your shop this year to check out your builds if you've got time.
We love that you're focusing on driver development on a stock vehicle. So many people think they have to have a "track build" before they can go to the track. By then you don't know what the car needs or doesn't need to suit your style and limitations of you and the car. We are happy to set something up for a visit. Follow us on IG (@justdriven) and DM us when you're ready and we can set something up.
I believe some cars have a poor alignment from the factory (you'll fix that after coilovers) and there is a bump steer problem ( but there is a kit for that). Have fun!
2:05? Worse than I imagined for sure. I used to do that in my 2014 Brz with springs, sways, rear CLA’ sand some nt01’s! Like I’ve said before, if they had actually brought the gr Yaris over here I would own one. But this slug, no thanks. Good luck with the build. Can’t wait to see what its gonna take to get under 2 minutes on 13CW!
@@JustDriven bad choice of words, im sorry. English is not my native language and i intended my reaction to be something positive. I altered my reaction. Keep up the nice vids, i watch everything .
Great comment! Will Wattanawongkiri did a 1.58.xx lap time on the same course (CW13) in a Subaru BRZ. That car had coilovers, Nankang CR-1 tires, brake pads, and custom setup. Will is a very high level driver and posted many track records at Buttonwillow. Danny managed to pull off a very respectable 2.04.xx in our STOCK GRC...basically a warm up lap, some traffic, then a hot lap. After that, we called it a day when the car went into FWD mode due to overheated AWD system.
While they do market it as a daily car you can take to the track pretty much, we can’t forget that it is just a street car. And expecting it to be a race car is unrealistic for $40,000.
Oh, yah, we agree. We also feel like we will have to explain this in the next video. Too many people are quick to jump to judgement on the car without ever having driven it!
You may want to highlight all the mods needed to make a Miata, at least the current one, track ready. Cooling, trans, diff are not race ready. Seems most cars are made to a minimum standard these days, over engineering has been replaced by cost accounting. A short list of current model track ready stock cars, I think, is pretty short.
@JustDriven I meant in a way of adding additional thermal capacity. I bet you guys will think of aftermarket coolers. Though I can add 1 liter more of fluid to my trans. Hope that made sense.
Did you drive it in "Sport" on track? Considering what was said at the end.... It's the understeery meme setting. Drive it in "Track" on track and on snow/slippery conditions, always, disable all electronic systems. / GR Yaris Circuit Pack owner
Use it on the Race Mode , not the Sport , cause the Sport give 70% to the rear You need a read diff cooler , is not the transmission If you use more grippy wheels will do the situation worst. Try to improve that first
That is disappointing to hear… I don’t understand why the manufacturers think we will just do a few hot lap and shut down for the day or something… people driving these need to run multiple laps to familiarize themselves with the car and the track even before doing time trials and that means multiple full 20 minute sessions.
because this is a road car based on a rally car. this doesnt happen on the rally car due to the very common spin and constantly losing traction. This car is not advertised or sold as a track car.
Agreed.. no one wants to deal with that. Especially from a car that's being sold as a "fun track car" that's "track day ready". I WAS honestly thinking of getting one of these. I'll keep looking for something else
@mengx94 The fk8 does overheat on a track, but it's the intercooler, not the front wheel drive transmission, which has the front diff in it... and it has an oil cooler for the transmission anyway... so, upgrade the intercooler on an fk8, and no problem. The fl5 is supposed to have an upgraded intercooler over the fk8. Hopefully, that fixed the CTR.
Now that's a nice open car trailer! Nice video. I'm interested to see what you all do with the GR We also learned the GR "track capable car" is really not a track car. Very unfortunate. Because I WAS planning on getting one of these for a fun commuter and a track day fun car.. I personally don't want to deal with overheating issues and possibly 4 wheel drive clutch pack issues or failures. That will QUICKLY turn a "fun driving car" into a stressful track day car.. no one wants to be worrying about a car known for overheating issues. Excessive High temperatures is the #1 killer of fluids and then comes part failure
@GR4Corolla there are possible fixes for this. But you shouldn't have to" fix" a brand new car that claims it was built for this very thing. That was it's 1st track day PLUS they mentioned it's engine oil was also getting very hot.. both engine oil and 4wd fluid overheating IS a recipe for a costly failure.
@@JustDriven I see. Looking forward to seeing hotlaps for the RCF. One thing is for sure, you won't have overheating issues lap after lap in the RCF because of how many cooling systems on it, there are for consistent lapping sessions. Just good tires and brakes. That is pretty much it. Cheers!
@@JustDriven make sure track is selected on the knob, put the car into sport driving mode above the shifter. And click the traction button. You should have a bunch of lights come on on the dash and it will say expert above the sport rectangle. It will disable any throttle cut and assists.
Some other commenters seem to agree with you. We don't have much experience with the Ford Focus lineup but it sounds like an adjustment to our driving selection and some cooling products and we should be good.
We're not so sure the exhaust routing is the main culprit, but it's not making things any better. We're leaning toward how the AWD system relies on a certain amount of clutch pack slip to actuate the rear differential. It's fun solving mysteries!
GR Corolla comes stock with the ducted front undertray. We need one for the rear, like the TRD designed unit for the GR Yaris. We're thinking about fitting the GRY rear tray...we'll see. Thanks for watching!
@@JustDriven doesn't t look like you had expert mode turned on.. pulls way harder in turns in expert mode... make sure its in track. Switch to sport drive mode and click the traction off.
Fun fact, the GR Corolla comes stock with Michelin Pilot Sport 4 tires, not the 4s tires. The Pilot Sport 4s' have more traction than the regular ones.
Damn, 240° oil temperatures and 40° temperature is not very good. Doesn’t leave a lot of room from adding more power. I would definitely look into an oil cooler.
@@JustDriven oil cooler should also add a quart or so of oil. get a setrab or other aluminum core oil cooler, skip the crappy mishi steel ones. also if you’re up for it, larger hood scoops. i’d also suggest some track pads that have more bite especially if you are towing it to the track. i bet a stiffer rear bar would help rotate without needing the 30:70, just a thought.
We have lots of plans for this thing. We want to see what it's capable of. This was just the "stock" track baseline run. Our partners we are working with on the build wanted to know what their parts will add to the lap times.
nothing to watch here, this is not a race car its a normal road car. shutting of the AWD system is a safety feature that works as designed and you can continue to drive the car in 2WD without any problems.

Congratulations on pointing out this problem on this fine car. Sure saves some people tracking their cars some potential headaches should they encounter the same issue. Could this fault be fixed under warranty or a recall?. Just wondering. Thanks.
this is not a fault, this is a side effect of the design of the AWD system. it literally works based on being able to apply friction with the clutch pack to make use of the 0.7% higher RPM being send to the rear diff. this was build for rally cars where spinning the tires and losing traction is normal so its less of an issue in that application.
Nah, we don't think there will be a recall. The AWD switch to FWD was just protection from us running the 30/70 torque split. If we used 50/50 it should have lasted longer. The price on these will drop when the supply catches up to the demand. Or they get a different car to markup instead?
@@JustDriven Yeah, I was hoping they'd do something cool for the 50th anniversary but no. I'll just have to keep driving this one. The outsides aren't the prettiest anymore but when you open the hood, angels sing
That's a shame, I expected more from a 40-50+ thousand Toyota. Hopefully this issue gets the attention of someone at Toyota and they do something about it 😔 Overheats in cool temps after a few laps? in the summer, it would be undrivable I'd imagine.
no, in summer it will simply switch to 2WD sooner if you push it hard. and this is not an issue, this is a side effect of the design of the AWD system.
Then maybe we aren't the RUclips channel for you. Sorry to waste your time. Thanks for commenting though. We know how hard that must be, time-wise anyway.
It’s a beautiful car it really is but I’m not sold on the price point. Especially with the Mark ups maybe I’m wrong here but i feel like you could spend less building something just as fun
You could spend less money building something just as fun. But not many people have had a chance to tune the GR Corolla yet. We wanted to try and play with this chassis for a little.

Same issue on Focus Rs with dual clutch GKN twister. Remedy is more air cooling the RDU. 👍
Thanks! Yah, we have lots of cooling to work out. If we have these issues with a stock car it's only going to get more intense as the mods go on.
Very cool car and video........ but THIS SHOULD NOT HAPPEN when the car is basically stock. Toyota needs to resolve this issue not the aftermarket community. What is the point of this car if you cant enjoy it?
It's protection for the components on the car. It's a little conservative in the ways it saves parts of the car from harm. In hindsight we probably could have used it in 50/50 torque split longer to to prevent this overheating so quickly instead of the 30/70. We were chasing fastest laps and much like the last video we were surprised it couldn't take a little more abuse.
What you don’t know yet, is that there ISN’T a physical temp sensor on the rear diff. The ecu is making a calculated guess.
I’m wondering what they change in the Morizo tune. 🤷♂️
We will take a deeper dive into cooling options soon. Thank you for your comments and input.
@@JustDriven BTW, check out the Motive Video channel. They reviewed all the steps and hurdles they encountered tuning the GR Yaris over a year. Even the dyno issues you came across.
Thank you. Someone else mentioned them so we've been checking them out. Lots of information in there.
Nice write up. You never really know until you take it to the track. I would expect you have to change the brake fluid and maybe pads (and tires of course). I have been taking a look at these newer "track worthy" cars to possibly replace my "95 M3 as the tech has come a long way in 25+ years. I wonder if R Comps or 200tw tires will help or make worse the diff problem.
Thank you for the view and comment! The stickier tires we used in later videos did not help the diff. problem. In fact, to this day we still don't have a solution that's solved it.
Honest ?: If you don't go to pure track tires, what's "up" from the PS4's?
We want something that works for street and track. Maybe something with a stiffer sidewall or maybe a little less sidewall. You'll have to check out what wheels and tires we picked out to see what we ended up going with.
Nice video. I'm surprised the car does not come with a tramsmission fluid cooler/radiator. My AMG Mercedes has one. Is it because of the AWD? Toyota knows these are going to be taken to the track. Does it have a engine oil cooler/radiator? That would also be good to have for thetrack.
We did beat this up quite a bit. We reveal in a new video coming soon the error of our ways and the method to our madness.
at the end of the day it has a slip-and-grip budget AWD system. Toyota owns Torsen and puts *true* mechanical center differentials on many of their Lexus cars and SUVs. I think Toyota went with this slip AWD system for mpgs, weight, and budget reasons...
We are not complaining. We will get to work finding ways to get around the car's short comings and get back out there.
no, they went with this because this system gives you control over how much power is being sent to the rear and because this was designed for a rally car where all of this is not a problem.
adding more rear diff fluid wont aid in cooling, a finned cover may help a bit, but simply adding more volume of oil just delays the inevitable.
Awesome information. Thank you.
In Australia, the Yaris GR had the same minor issue with the clutch pack heat... many fixes are available on the aftermarket, no big deal.
Yah. We don't suspect it'll be a crazy ordeal.
@@JustDriven Your title had me freaked out though as I have one on order 😁 great potential in those engines though, we get some big numbers down here.
Sorry. We see it is a major flaw that a car meant to be driven hard, seems can't be driven TOO hard. But we will update everyone with what we did to hopefully correct this.
We don't want to spend a ton on this car to have it hammer out some great lap times. So we started ironing this out as soon as we got back to the shop.
@Adimoolah it's not about mechanical strength, it's about thermal ECU intervention due to the exhaust heating the rear diff. Check out Motive on RUclips, they got 500HP (Yaris GR) and no mechanical failures after lots of thrashing, they have very strong components, just a big screw up with their exhaust and diff placement which is easily fixed.
Subscribed to follow the build!
Awesome! Thank you so much for showing us some love with the sub.
Talk to the guys in Australia, Motive Video (RUclips) they have made one of the fastest gr Yaris. I'm pretty sure they ran into this and have a fix for it 👌. Just watch their Yaris build. They go through all pros and cons and what they have done to rectify certain issues. PEACE!!!
Thank you for the information. We are aware of the guys from Motive. They are doing amazing things with the GR Yaris. We are just trying to get to the route of some of the issues with owning the GR Corolla as a street car. We have some cool things coming for treatment for the cooling issues.
Laughing at all comments dissing the car for the well documented and easily fixed AWD overheat issue. Air duct and/or exhaust wrap solve this immediately. If you are adding more grip and more trackdays then a larger aftermarket rear diff oil container is ideal. The GR Yaris and Corolla are few of the best and budget options for dual purpose use (daily, weekend toy, occasional trackday) out of the box. Try taking any sports car/ hot hatcg in the next price bracket with stock rotors and pads on a trackday and see what happens.
So many people saying they would not buy this car based on this video. Uh, you weren't going to buy it anyway. Comparing it to the wrong cars and price points. Where has all the common sense gone?
Toyota designed the rear clutch pack to constantly slip ever so slightly for "better" distribution of power. It was only bound to overheat.
Yah, we will address this first. Next video we will discuss how we plan to tackle this issue.
What happened to the breakin period?
It was done earlier in the video.
Have you checked that the transport blocks have been removed from the front springs some dealers forget to do it on the predilvery cheak
Uh yup!
Should get elantra n for tracks. Heard thats one of the best on track as far as heat management is concerned
We wanted to develop the 3 cylinder in the Corolla. We can fix the cooling issues. Just having fun.
Sorry if mentioned and I missed it, but did you guys figure out the power issues from the dyno video?
No issues that we know of. Just lower than we expected power. Maybe next time on dyno it will have more power?
Is it a MAJOR flaw, or is it a flaw on track? I’m not certain that every gr Corolla owner is going to rag doll the car around on the street. Yes, it is disappointing that the AWD system disengaged in cooler weather… but then again I’m just glad Toyota even made the damn thing 🎉
daOh we are beyond happy they made it. We love the car despite the overheating and the lack of power on the last episode. These are just forms of data for ourselves. Is it a flaw on track? Yah, the title is "Track Day | We Discover A Major Issue." It's not " Street Driving | We Discovered A Major Issue." Many tend to think we are disappointed in the car. Not once did we say we didn't love this car.
knowing how the system works, using sport mode on track instead of track mode was unwise...
We switched between the different modes depending on the lap.
When the awd system over heated did it default to front wheel drive?
Yes, it is an issue on some other cars using clutches to redirect torque. Going 50/50 split may alleviate some of this as the clutches shouldn't be slipping.
were you guys tracking at 30/70?
Yup common issue with the system as the clutches are always slipping. Owners of the GR Yaris had the issue on and off since release.
We tried Sport and Track modes and 30/70 and 50/50. Danny was using different setups for optimum lap times.
I drive my GRY in sport mode to help combat this issue as more rear bias means less slip at the coupling. I also plan to get the syveccs AWD controller as it reverses the lock up strategy which reduced slip a lot. That said bog stock I’ve done 300km in a day on track in 35 degree heat without an issue. Try sport mode if you haven’t already!
Thanks for watching. Next track day we'll be better equipped from what we've learned so far. We appreciate the advise!
I thought it was the other way around. Fwd only mode means the clutch pack is completely open. For track mode the clutch needs to close a bit, so you have 50:50. Sport mode is 30:70 meaning that the clutch pack needs to close even more in comparison to track mode in order to deliver more torque to the rear. Am I wrong?
@@TTTonyTurbo yes that means the clutch is allowing less slip and therefore generating less heat when in sport as opposed to track.
when i test drove the GR i did one hard launch in 30/70 mode and it shut down the rear diff for 30 minutes because it overheated. its not exhaust heat causing it, its internal friction and too sensitive of a temperature sensor on the rear electronic clutch pack. big design flaw imo and why i prefer a pure awd system like subarus.
Yah, and it may be a bit more sensitive when it hasn't been broken in yet. Launching on a test drive isn't something we would recommend.
@@JustDriven it was a press car with about 6k miles on it. They were having plenty of issues with it for sure. But when I had my go, I did a launch just like everyone else, and boom. No more awd.
I saw you guys at Buttonwillow that day! I have a stock red GR86. Looking forward to the build.
Heck yah! We saw you too. What are your plans for yours?
@@JustDriven I'm competing in stock class in the 86Cup, so I've got absolute minimal mods for the year. My main focus is driver development. Maybe I'll drop by your shop this year to check out your builds if you've got time.
We love that you're focusing on driver development on a stock vehicle. So many people think they have to have a "track build" before they can go to the track. By then you don't know what the car needs or doesn't need to suit your style and limitations of you and the car. We are happy to set something up for a visit. Follow us on IG (@justdriven) and DM us when you're ready and we can set something up.
I believe some cars have a poor alignment from the factory (you'll fix that after coilovers) and there is a bump steer problem ( but there is a kit for that). Have fun!
Thank you! We hope to have much better times (and longer sessions) next time out.
2:05? Worse than I imagined for sure. I used to do that in my 2014 Brz with springs, sways, rear CLA’ sand some nt01’s! Like I’ve said before, if they had actually brought the gr Yaris over here I would own one. But this slug, no thanks. Good luck with the build. Can’t wait to see what its gonna take to get under 2 minutes on 13CW!
We are hoping the next parts haul will help get us there. New video coming soon on what we are doing.
Issue right at 14:00 for those who were too eager and curious to know just like me.
@@JustDriven bad choice of words, im sorry. English is not my native language and i intended my reaction to be something positive. I altered my reaction. Keep up the nice vids, i watch everything .
We removed our reply too. We appreciate the support.
Just wondering, to give the GR corolla context, how did your best lap time compare to other cars like civic type R or whatever was at the track
Great comment! Will Wattanawongkiri did a 1.58.xx lap time on the same course (CW13) in a Subaru BRZ. That car had coilovers, Nankang CR-1 tires, brake pads, and custom setup. Will is a very high level driver and posted many track records at Buttonwillow. Danny managed to pull off a very respectable 2.04.xx in our STOCK GRC...basically a warm up lap, some traffic, then a hot lap. After that, we called it a day when the car went into FWD mode due to overheated AWD system.
Michelin Pilot Sport 4 (not 4S), aren't they?
Not 4S.
While they do market it as a daily car you can take to the track pretty much, we can’t forget that it is just a street car. And expecting it to be a race car is unrealistic for $40,000.
Oh, yah, we agree. We also feel like we will have to explain this in the next video. Too many people are quick to jump to judgement on the car without ever having driven it!
You may want to highlight all the mods needed to make a Miata, at least the current one, track ready. Cooling, trans, diff are not race ready. Seems most cars are made to a minimum standard these days, over engineering has been replaced by cost accounting.
A short list of current model track ready stock cars, I think, is pretty short.
The Hyundai N cars hold up pretty well…
@@oraclemiata845 lol be careful with talk about the Hyundai cars “””holding up”””
Is there more room for additional fluid?
No. The fluids were checked before heading out.
@JustDriven I meant in a way of adding additional thermal capacity. I bet you guys will think of aftermarket coolers. Though I can add 1 liter more of fluid to my trans. Hope that made sense.
I just picked up a second job hoping I can pick one up in May... Wish me luck 🤞
Best of luck!
Did you drive it in "Sport" on track? Considering what was said at the end.... It's the understeery meme setting. Drive it in "Track" on track and on snow/slippery conditions, always, disable all electronic systems. / GR Yaris Circuit Pack owner
We tried both Sport and Track modes to see which yielded the best track times.
Use it on the Race Mode , not the Sport , cause the Sport give 70% to the rear
You need a read diff cooler , is not the transmission
If you use more grippy wheels will do the situation worst. Try to improve that first
Tell us more about this "race" mode. Thanks for watching!
So the car can drive two wheel drive, will it let you do that on purpose?
yes you can choose between 2WD aka 100/0, 60/40, 50/50 and 30/70 torque split.
@pixelplanet5 is correct.
That is disappointing to hear… I don’t understand why the manufacturers think we will just do a few hot lap and shut down for the day or something… people driving these need to run multiple laps to familiarize themselves with the car and the track even before doing time trials and that means multiple full 20 minute sessions.
because this is a road car based on a rally car.
this doesnt happen on the rally car due to the very common spin and constantly losing traction.
This car is not advertised or sold as a track car.
@pixelplanet5 🤘🏼❤️
Nice, another Focus RS that can't last a full 20 minute session
At least the civic type r doesn't overheat
@@mengx94 we’re talking awd🤣
@@mengx94 It literally does... We don't know about the brand new one yet though.
Agreed.. no one wants to deal with that. Especially from a car that's being sold as a "fun track car" that's "track day ready".
I WAS honestly thinking of getting one of these. I'll keep looking for something else
@mengx94 The fk8 does overheat on a track, but it's the intercooler, not the front wheel drive transmission, which has the front diff in it... and it has an oil cooler for the transmission anyway... so, upgrade the intercooler on an fk8, and no problem. The fl5 is supposed to have an upgraded intercooler over the fk8. Hopefully, that fixed the CTR.
Now that's a nice open car trailer!
Nice video. I'm interested to see what you all do with the GR
We also learned the GR "track capable car" is really not a track car. Very unfortunate. Because I WAS planning on getting one of these for a fun commuter and a track day fun car..
I personally don't want to deal with overheating issues and possibly 4 wheel drive clutch pack issues or failures.
That will QUICKLY turn a "fun driving car" into a stressful track day car.. no one wants to be worrying about a car known for overheating issues. Excessive High temperatures is the #1 killer of fluids and then comes part failure
Err, what car fits your criteria then? Every car will have some issues when track driven
There are simple fixes for this, so I wouldn’t disregard it completely
@yourmotherlovesit That's simple, a car that doesn't overheat its 4wd system after during a 25-minute track session.
@GR4Corolla there are possible fixes for this. But you shouldn't have to" fix" a brand new car that claims it was built for this very thing.
That was it's 1st track day PLUS they mentioned it's engine oil was also getting very hot.. both engine oil and 4wd fluid overheating IS a recipe for a costly failure.
What other fully stock cars in this price range that doesnt have issues when you track it hard?
Ipone Xtreme fluid is cheaper than RBF600 but slightly higher spec than RBF660
Thanks for the tip! We'll look into it. We have friends at Motul, so hey...Motul it is ;)
Keep us updated! I think its the rear diff for sure.
We will tackle any and all issues it could be and update everyone with what's been done.
You were going to do track hotlaps in the Lexus RCF? Still waiting for that video. Is it on the radar still?
We want to take the RCF out also! We will see. We have a bunch of partners on board with this GR build. Makes getting track days for it much easier.
@@JustDriven I see. Looking forward to seeing hotlaps for the RCF. One thing is for sure, you won't have overheating issues lap after lap in the RCF because of how many cooling systems on it, there are for consistent lapping sessions. Just good tires and brakes. That is pretty much it. Cheers!
The brakes are pretty awesome to begin with! We think tires and aero will help keep that tail end from getting too crazy!
@@JustDriven Yeah transmission cooler and engine oil cooler (behind each vent on the front bumper) as well as brake cooling.
I just go the 2024 model any update to see if this issues has been fixed?
This is still an ongoing issue. We do not love this car any less though. It's so much fun!
@@JustDriven Great video nonetheless. I'm local so if I need anything or if u fix the issues I'll consider it in the near future
Did you have the expert mode on?
Tell us more about this "expert" mode...
@@JustDriven make sure track is selected on the knob, put the car into sport driving mode above the shifter. And click the traction button. You should have a bunch of lights come on on the dash and it will say expert above the sport rectangle. It will disable any throttle cut and assists.
Thanks for the information.
Hopefully a new exhaust and diff cover helps with the temperatures
It may take a bit more but that's okay. We are prepared to get need some work to get this thing to stay cool.
It s serious ! Thanks ;)
Thank you.
I belive Ford Focus RS have same problem with 4WD system overheating when track driving.
Some other commenters seem to agree with you. We don't have much experience with the Ford Focus lineup but it sounds like an adjustment to our driving selection and some cooling products and we should be good.
So, center exhaust pipe that's right under the key diff wasn't such a great design call, huh?
We're not so sure the exhaust routing is the main culprit, but it's not making things any better. We're leaning toward how the AWD system relies on a certain amount of clutch pack slip to actuate the rear differential. It's fun solving mysteries!
Before I read anything or go beyond first 10sec, let me guess... rear diff overheat? =D
Part of the fun of storytelling in all its shapes and forms is to enjoy the story. haha...
actually no.
rear clutch pack overheating.
You need the front undertray with the diff cooler scoops like on the GR Yaris
GR Corolla comes stock with the ducted front undertray. We need one for the rear, like the TRD designed unit for the GR Yaris. We're thinking about fitting the GRY rear tray...we'll see. Thanks for watching!
Next track-day, let’s see some host vs host hot laps 😉
James would smoke them all! Wait, is "smoking them" when you don't even leave the pits yet and everyone is already done fast laps?
@@JustDriven doesn't t look like you had expert mode turned on.. pulls way harder in turns in expert mode... make sure its in track. Switch to sport drive mode and click the traction off.
Thanks for the video! You may have misspoke, the tires are just PS4 (not S) - not bad for a non-S.
Yah, he did. We keep teasing Alex about it too. Hopefully when he ordered the wheels he ordered the right ones!
@@JustDriven hahah amazing. love it. keep it up guys!
Thanks for the comments and the firepower for baggin' on Alex!
Fun fact, the GR Corolla comes stock with Michelin Pilot Sport 4 tires, not the 4s tires. The Pilot Sport 4s' have more traction than the regular ones.
That is fun! Thanks.
@@JustDriven lol I hope that didn't come off rude, I just kinda caught it while listening and figured I'd comment. Great video!
Nope. We didn't take it as rude. We appreciate you taking the time to comment!
Such a funny fact…
there's an Alpine CVA-1005 on ebay rn for 600$... a rare piece for a correct f&f eclipse!
Great headunit! We have alerted James. Thank you for the heads up.
Looks nice in white
It looks so good in person.
Damn, 240° oil temperatures and 40° temperature is not very good. Doesn’t leave a lot of room from adding more power. I would definitely look into an oil cooler.
We are looking into anything to keep this thing cool at the track for our next time out.
@@JustDriven oil cooler should also add a quart or so of oil. get a setrab or other aluminum core oil cooler, skip the crappy mishi steel ones. also if you’re up for it, larger hood scoops. i’d also suggest some track pads that have more bite especially if you are towing it to the track. i bet a stiffer rear bar would help rotate without needing the 30:70, just a thought.
i’d also pull the disc brake dust shields
We have lots of plans for this thing. We want to see what it's capable of. This was just the "stock" track baseline run. Our partners we are working with on the build wanted to know what their parts will add to the lap times.
the problem is not the engine oil temp, its the rear clutch pack opening up to prevent heat damage.
Hopefully Toyota is watching this video, regarding the overheating AWD system.
nothing to watch here, this is not a race car its a normal road car.
shutting of the AWD system is a safety feature that works as designed and you can continue to drive the car in 2WD without any problems.
Hey Toyota! You gotta see this Just Driven video! We like how you think @stopspin
That is the coolest trailer ever
It is pretty awesome. Alex uses it for his track cars. It makes for a lot less work with lowered cars to get it on and off the trailer.
The gr corolla in white looks very nice…
It was our first choice. Lucky for us that's what we got.
Gotta take mine to a track
It's so much fun.
When dreams of ..META TARO BLURAY...start out as ..DOKI DOKI MORNING...only the GR god knows

15:03 shows tire was under inflated. Driving half way down the side wall.
We were on top of the tire pressures all day. In between sessions and after laps when we changed the drive modes.
Hey just driven I found an original parts for eclipse I check it an it’s original one of one alpine cva 1005 head unit tv/dvd on sale eBay and it’s the original used in the movie
That's so cool. We love some Alpine stuff. Someone else mentioned this head unit to us also.
There’s a new hot hatch on block ❤❤❤
As a Australian with the gr yaris Rallye, cant wait to see the Americans modified these and beat those v8's I see from RUclips in a 3 cylinder corolla haha. Those g16 engines getting 500hp+ at the wheels so far with bolt ons can't wait till the Americans start finding ways to add more power
This thing is a ton of fun to drive. We can't wait to squeeze more power out of this thing. And get it to translate into faster lap times.
Congratulations on pointing out this problem on this fine car. Sure saves some people tracking their cars some potential headaches should they encounter the same issue. Could this fault be fixed under warranty or a recall?. Just wondering. Thanks.
this is not a fault, this is a side effect of the design of the AWD system.
it literally works based on being able to apply friction with the clutch pack to make use of the 0.7% higher RPM being send to the rear diff.
this was build for rally cars where spinning the tires and losing traction is normal so its less of an issue in that application.
We are all talking about @pixelplanet5 handling all comments from here on. He's nailing it!
They better start dropping the prices on these after a recall is done.
Nah, we don't think there will be a recall. The AWD switch to FWD was just protection from us running the 30/70 torque split. If we used 50/50 it should have lasted longer. The price on these will drop when the supply catches up to the demand. Or they get a different car to markup instead?
I'm still waiting on a retro body version like my '68 KE10.
Toyota doesn't usually tend to do much retro stuff. That's more of a US car manufacturer thing. But your idea would be so awesome.
@@JustDriven Yeah, I was hoping they'd do something cool for the 50th anniversary but no. I'll just have to keep driving this one.
The outsides aren't the prettiest anymore but when you open the hood, angels sing
And the clouds part.
That's a shame, I expected more from a 40-50+ thousand Toyota. Hopefully this issue gets the attention of someone at Toyota and they do something about it 😔 Overheats in cool temps after a few laps? in the summer, it would be undrivable I'd imagine.
We did push it hard with 30/70 splits. We are reading it may prefer 50/50 more without overheating. We will try this more next time.
no, in summer it will simply switch to 2WD sooner if you push it hard.
and this is not an issue, this is a side effect of the design of the AWD system.
I’m in the Irvine/Tustin area with an evo x. Hope to see you around!
Heck ya! You'll likely see one of us or one of our shop cars out there.
Amazing
Thanks! We had so much fun!
As much as I like Toyota, the more I learn about this car the more I'll either stick to my VN or would purchase a Supra with a Manual...
Staying true to your VN, good call. Supra MT, good call. You simply can't go wrong. Thanks for watching!
ain't the diff off a rav4?
We haven't heard this. We will look into it.
No flat out over the hill?
On another lap he was flat out. We captured his fastest laps here.
You’re gonna need to buy another tow hook to run both front and rear at the same time!
Fo sho! We borrowed one from another Toyota in the fleet. Thanks for watching!

Looks like a Factory Five 818
Great....
Great...good? or great...bad?
Same issue with my FK8.
Gnarly. Just overheating?
i can't afford this car and now i'm really not buying it lol great video!
Thanks? haha...This car is beyond fun. We recommend anyone who can get a chance to go drive one.
Put time stamps or get to the point immediately cuz ain’t nobody got time to watch
Then maybe we aren't the RUclips channel for you. Sorry to waste your time. Thanks for commenting though. We know how hard that must be, time-wise anyway.
It’s a beautiful car it really is but I’m not sold on the price point. Especially with the Mark ups maybe I’m wrong here but i feel like you could spend less building something just as fun
You could spend less money building something just as fun. But not many people have had a chance to tune the GR Corolla yet. We wanted to try and play with this chassis for a little.
