MR2 Snap Oversteer

- Here are a couple of clips of my mistakes from autocross over the past three years driving my 1991 Toyota MR2. I know most of these videos aren't actually "snap oversteer", they are lift off over steer or throttle oversteer. / mr2_nate
Good examples of lift off and throttle oversteer
Yeah, most of that oversteer was lift throttle induced
And brake oversteer.
Do you find yourself braking during the turn? That is usually what causes it with a MR platform.
Sometimes, even by letting go the acceleration dramatically; it will cause a shift in weight causing the rear to kick out
The first four clips are just lift off oversteer, I lifted off the throttle mid corner. I've learned since then and never lift while turning, and I try to brake in a straight line. And the last two clips are throttle oversteer.
I wanna get one as a first car so badly, but they just scream red flags at me when I see these vids lmao
Snap oversteer really isn’t as bad as the internet says it is. Most of the time it’s just driver error. But I probably wouldn’t recommend getting an MR2 as a first car. They have gotten pretty expensive and aren’t the most practical. Get something fun and fwd like a Honda Fit. And take it to an autocross event so you know how to control it at it’s limit.
things I learned about Mr2 are you don't brake while cornering and don't correct the tank slap.. kinda make you think like riding a bike
I've never driven a mr2 but i kind of have the same thoughts as you. It's seems to be pretty similar to riding a bike in a weird kind of sense. Rolling off the throttle abruptly mid corner on a bike or braking hard in the middle of a turn will result in a crash. On the mr2 it seems to results in a similar kind of desaster
To correct oversteer - inflate front tires UP To 2 PSI lower than the rears
no opposite!!
@@linray16 Yes - Thanks
I’m confused… Are you saying to raise or lower the PSI? You said inflate up to 2 PSI lower. Did you mean deflate instead of inflate?
I found out while just driving around my roundabouts that you can use liftoff oversteer by either braking or lifting off the trottle in order to combat understeer. I have only snapped due to unclean surfaces and even me who just got their license was able to recover. I think this shows the differences between the AW11 platform and the SW20's severity of snap oversteer. But I believe both platforms can use it to be faster
I guess it's basically weight transferring at that point, but it really likes to do it nicely
Yeah lifting or braking can really help the car rotate. I don't think the "snap oversteer" is any worse on the sw20. Most of that is just driver error.
@@mr2_nate yeah, I have never driven an Sw20 so I wouldn't know, I just hear they are more prone to the liftoff oversteer and such
Totally induced fun.
In real life I've never had a problem.
I’ve spun out at the same corners at DCTC where you’ve spun out. Mainly in my civic though, sometimes they don’t prep the track well. I was able to sweep the track once at the start of the day and grip was there. Later during the day people riding the shoulders and put more gravel on the roads made it slick.
Correct me if I'm wrong, but did that MR2 get a v6 swap halfwaz trough the video? Awesome either way
Yep! I swapped in a 2GR the winter of 2019/2020.
The backend wants to break free like a bad child in a toy factory 😅🤷🏾♂️
If you play a racing sim (iracing, assetto Corsa, project cars 2), with no anti lock brakes and a mid engine car, you'll learn very quickly to be paranoid of braking and turning haha
any car you play is different so when you jump on a real car you’ll still have to learn how it behaves at the limit… imo you’ll still have to do braking while turning 🤷♂️
@@rotorblade9508 Yeah, my point is that some people have no fear of it, especially if they drive a car with a heavy frontal weight bias. They have always experienced understeer if they brake too hard into a corner. When I sim raced in project cars 2, I had to be very careful of braking/turning too much under corner entry with no ABS because the first warning was usually a full spin lol. I feel like this really helped me understand what to look for when I'm approaching the limit with my Porsche boxster. I've still spun once or twice trying to hit that limit :P. It's almost easier irl because you get so much extra feedback from noise/vibration/g forces, so I felt like I was relearning a bit but with some extra help.
Install a Wilhelm racing geometry correcting kit. This + disconnecting the rear sway bar+ fortune auto coil overs and my car never oversteers, just grips now.
That’s my exact suspension setup in most of these clips lol. But now I’ve ditched the junk fortune auto coilovers for some Wilhelm Koni coilovers.
It looks to me like you're overcorrecting your oversteer. And you're accelarating after leaving a turn while also turning again at 1:45. Like you leave the turn there, and accelarate heavily while steering to the left. You'll lose grip rather quickly.
Driver mod right there
You had faster hands than me!
What intake/exhaust setup did you have on your 5S-FE? It sounded pretty good in the clips before the swap.
eBay “cold” air intake and stock exhaust
@@mr2_nate guess i gotta pick up a ebay intake for mine, thanks
@@KrashKan No problem. Just so you know the eBay intake probably makes less power than the stock intake. But it does sound pretty cool.
Who is the overseer of snap?
Well I guess I am, because I can't fricking spell! 😂
@@mr2_nate It's alrite, corect spelling is overated 🙃
why are you accelerating to hard? can't you like ease into the power rather than just hammering down?
So glad the aw11s aren't this twitchy
Nah they aren’t “twitchy.” Everything that happened in these clips was my fault/driver error.
It's possible to fix snap oversteer?
Lotus Elise doesn't have a rear ARB(Sway Bar) maybe to reduce Snap oversteer?
“Snap oversteer” is mostly just driver error and the rear toe curve on MR2s. But I have that fixed now with a Wilhelm Raceworks Geometry kit. And I already have the rear sway bar removed.
1:05 this is what snap oversteer actually is. In FR cars you have more leeway when correcting a steer. But due to the heavy weight on the rear tires in an MR, over correction is very easy and very snappy.
The title is a joke and snap oversteer is a myth.
s54 2gr correct?
Yep! At least in the last two clips, the first few clips were with the 5SFE.
@@mr2_nate You're running the S54 transmission with your 2GR? How's it been holding up for you? I have a 5SFE and am thinking of doing the swap but sourcing an E153 is obnoxious.
@@Domi39 I used to run the S54 transmission with the 2GR. It lasted over a year and a half of 7,000 hard miles and 20 autocross events. It should last the average person forever, just don’t launch it super hard.
@@Domi39 I’m pretty sure the spider gears inside the oem S54 differential broke because I’ve heard that’s the weak point. Thankfully I was still able to drive it home after it broke. So theoretically if you replace the differential with a limited slip diff out of a MR2 Spyder or an aftermarket LSD, you should have a transmission that’s a lot stronger.
@@mr2_nate Thanks mate I really appreciate the input.
Damn is it that common? I picked this up with hopes of doing scca as well, but this isn't very encouraging. Is there much you can do suspension wise too get past this?
It’s not that common, most of these clips aren’t even snap oversteer. They are actually just lift off oversteer or throttle oversteer. And you have to realize this only happened to me five times over the past three years and I probably have done over 500 autocross runs during that time. Just make sure you don’t lift or break mid corner and you’ll be good. Also you can get a Wilhelm Raceworks geometry kit in order to fix the suspension geometry.
Okay that makes sense thanks for that info. Definitely looking up one of these kits once I get to that point
@@omnipotentgoku Yeah Alex from Wilhelm Racworks makes a bunch of great parts for these cars. Including 2GR swap parts and suspension stuff.
@@omnipotentgoku
Hope you have deep pockets
Make sure you stagger your tires properly to maximize the handling of your car.
in all those clips you snap steered once 1:02, the rest are just normal oversteer.
Smooth throttle on and off, prevents this. You drive it like it's fwd, can't be doing that in any rwd, no mashing the gas
Any videos on the correct way to correct this?
1. Wilhelm Raceworks Geometry Kit
2. Good tires
3. Seat time
Well Snap!!!!!
Driver error
Yep! It was my fault every time haha
Practice makes perfect 👍🏼 sick car bro
@@jakewhitear1928 Thanks!
nah the MR2 has the worst snap oversteer even great drivers will hop in one and spin out
@@billbob9570 if your a girl
Did you ever had the experience of driving a motorcycle?
I’ve driven a couple mini bikes, but that’s about it.
@@mr2_nate if you still got the MR2, let it pause and try to learn a 125cc or a 250cc bobber style which has the best handling, and the training and learning curve you have from the experience driving the motorcycle will go into the MR2. Driving without braking is a staple in motorcycles and you get to use a lot more the engine fluidly. But hey that's my take since I got the experience it made me open up more as a driver. Wish I the best
@@mr2_nate wish U the best**
I got an 11½" wheel in my '2 to combat this, (not that it's really that normal of an issue..)
Well more tire is always better! Right now I have a 8.5” wheel with a 245 on the rear. If I wanted to go wider I’d go with a 9.5” wheel and a 275.
@@mr2_nate I was referring to the steering wheel size (easier to keep up with direction changes)., IMO wider tires aren't worth it, unless you are running chemical grip compound wider tires don't increase grip whatsoever, they can change handling (IE oversteer/understeer) by how much scrub is on one end Vs. the other but such handling is much better sorted at the suspension (IE remove rear sway/[anti]roll bar)
@@ChroniclesofKToyodaAhhhh okay. I want to get cruise control working with my 2GR. So I think I’ll keep the oem wheel with the cruise control stock.
I completely agree with you about that! I’m already running 200tw tires, the best tires I can for my autocross class. And my suspension is already fully sorted with no rear sway bar, Wilhelm geometry kit and so on.
@@mr2_nate going away from the stock wheels will greatly improve control tbh. The stocks are just too small for what you're doing, hence why there are so much spinouts haha! I have 17x8 all around and it's so much better.
@@mushlove6933 All of these were with 17x7.5 and 17x8.5 wheels with 215/245 200tw sticky tires. I never raced it on the stock 14” wheels lol.
Lol why would anyone volunteeringly be his passenger
Because they have a death wish🙂
Is there anyway to over come this???? 😂
Your driving has to "be like water" in order to go fast in a sw20😂
All the shit they market as sports cars these days... 🤔
Wut
MR2 was originally marketed as a fun economy roundabout🤷🏼that's why this one came with an FE Camry engine & the Original AW chassis as a 1.5L SingleCam base model(admittedly no one bought those)
1:32 Americans driving manuals be like
Please explain lol
Sounds like a normal start with a lightweight flywheel
@@notgooddriver8395 Also the transmission I had at that time wasn’t the strongest, so I was trying to go easy on it.
