Honestly if you need a good solid street pad Carbotec 1521's worked great in my RR racing BBK (wilwood calipers). Zero Squeal and I just swapped to XP 10's/8's for track days with no need to re-bed etc...
Do not use other pad compound than Wilwood Polymatrix "A". I tried them all. Also, for next rotor go for heavy duty curved vane (Wilwood HD or GT series).
Sorry if this is a really stupid question, but I have to ask... If we've ensured that there's wheel clearance, and of course the brake pedal isn't depressed, what are we hearing at 10:15? Did your wheels make that noise with the old brakes?
When you bleed the brakes after install, the calipers squeeze onto the rotors since you've pressed the brake pedal. When you let go, the caliper releases, but just enough that the pads just barely touch the rotor. That's what you're hearing. That material will get abraded pretty much the first time you bed in the brakes.
Most of the racing big brake kits do not have dust boots I believe. I can't say for long term street use with them because I mostly track my car. But they are rebuildable and worst case it's $300 per caliper.
These are so nice! But I don't think these will fit RPF1 17x9 with the +35 offset that I have unfortunately. The +45 you have has even more clearance due to spoke design.
Do you think it would be worthwhile to try the pads with the 50mm radial depth? Assuming the pads on this kit are the standard 41mm ones. Curious if they would fit.
Great point! yes, i think it's worth trying. I measured the radial depth as 44mm on these pads. But I think they can work with the 50mm pads, which I'd prefer because they use more swept area for more even heat dissipation. I personally would try 50mm pads next time I change rotors.
How are you liking the Wilwoods? So here is the deal, I have a 2023 GR86 that I track(we tracked it 9 times already, it works great on Castrol SRF fluid and Hawks DTC-60 pads but the pads are now showing signs of deterioration. Simultaneously I also have another track car(8TH Gen SI) with Wilwoods 6 piece forged calipers and 2 piece rotors and they are tough as nails. Absolutely no signs of wear on the rotor and very little wear on the pads. I use BP10 pads for the streets and BP 30 for the track. Do you wholeheartedly recommend the Wilwoods specially if we track the car? I probably have another 4-6 track days before I would have to swap pads again and that will set me back 400 (front and rear on the Hawks DTC-60s) . Any feedback is appreciated.
My take is the Wilwood kit holds up reasonably well for its price if you are able to choose the right pads to use. I would recommend the two piece DBA rotors since the one piece version cracked after 9 days for me. However, the AP racing endurance kit is the can't go wrong option if budget allows. I have upgraded to AP kit and I'm very happy with its performance.
@@TrackandBuild I love AP Racing and I have seen the deals that they had a couple of months ago, I think it was like $1000 off or 20% off (I can't remember) but it was too much money to put on the car considering that I am trying to get suspension too. The DTC-60 are phenomenal but Wilwood is a better deal for the price. I don't just want to do Brembos because people don't get the concept. Brembos are good for sport /street driving but they have rubber or silicone booths while true racing companies like AP or Wildwood uses steel pistons with better metallurgic and no booth which works better at then track. Also, brembos offer sports pads not really track pads, you would have to go and spend again money on track pads. Thanks for your advise on the 2 piece rotors, I did not know that DBA had 2 piece rotors. My OEM rotors are holding up very well, no grooves yet and 9 track days already. No warping either so it looks like the DTC-60 compound brake pads are managing the heat very well absorbing all the heat.
nice informative vid. BTW, your brake bias calculator has a bug: ` var p_area = area(d1/2.) + area(d2/2.) + area(d3/2.); //inch ^2` should be ` var p_area = area(d1) + area(d2) + area(d3); //inch ^2`
Hello, u kept the rear brakes stock? Doesnt that create massive disbalance between front and rear breaking affect? Also when u installing BBK why not swap to braided brake lines?
Yes, rear is stock. This kit is designed to have the same bias to the OE so bias is not changed. Braided lines are not a must based on my personal experience (I had them on my other cars)
Hi, I work at RR Racing where you purchased the brake kit. I would love to ask you a question pertaining to the brake kit. If you could shoot us an email or a call It would be greatly apreciated. - Thanks , Justin
Safety is always one's own judgement after all. For me, it is safe as long as corresponding long studs are used. Using 15mm spacer on ET45 wheels are equivalent to using ET30 wheels in terms of suspension geometry. Yes scrub radius will change but no dramatic changes in handling for me.
Brembo has a GT BM4 kit that would fit this car. I also tested its template fitment in this video ruclips.net/video/oIKKfu1e5Bs/видео.html They are very wide so I doubt they will clear the OE wheels without spacers.
awesome video, very detail instruction. is there a reason you use a single piece brake rotor instead of 2 pc rotor? do you also need to upgrade the rear brakes to balance out weight transition while braking?
Thanks. Single piece rotor is much cheaper and can be upgraded to two piece rotor in the future. This kit maintains the brake bias as OE per my calculation so I did not change the rear.
This car is great for track out of the box. It's not a slow car considering its size and weight. basically the power level is on par with the S2000. It's a platform with great potential.
Hey Thanks for the video. Is this kit specific to the 22 brz ? I heard the knuckles on the 22 brz are different size to previous gen so the previous gen caliper brackets Do not fit . You didn’t seem to have an issue

Thank you so so much for doing the research and testing and sharing your results and review. Please continue to do these great, detailed videos
glad it's helpful!
This channel deserves more views and subs!!!!!
thanks man. glad you liked it.
Best part for me was that you had clearance with the OE 17" rims. Looks like a nice cost-effective upgrade.
If you're gonna install a nice brake kit like this one, you should also change the brake OE rubber brake lines for braided steel brake lines.
you can (most people do that, I also have them on my other car) but it's not a must.
stock ones are steel braided on the inside
@@JFlogerzi i thought the same thing
Looks like a job for the entire day! Really enjoyed the video - looking forward to seeing your progress with the 86 moving forward
Outstanding video, thank you for sharing the full details on this swap.
Around 2:47 you farted! Don’t lie!!!! Anyways, this video is very helpful. In the market for a track bbk that is for function and not for show.
Great video, good luck with the channel!
Wow you deserve way more subscribers. Nice vid. Been shopping for brakes on mine.
Such a solid video, thank you!

Why curved vane?
@@lomfmur lot better coling
I dont even have a GR86 or BRZ but i watched the whole thing. Impressive!
thank you for such amazing experiment
Great video! Keep on the good work!
Thanks! I surely will😆
Can you share the part number of the rotor you used? Just want to make sure I'm pricing out the DBA rotors properly.
Sorry if this is a really stupid question, but I have to ask...

The lack of clearance between the brake caliper and the inside of the wheel is troubling. If a rock lodges in there... damn.
Those Wilwoods don't appear to have dust boots on the pistons. How streetable would those be for a daily driver in wet weather?
Most of the racing big brake kits do not have dust boots I believe. I can't say for long term street use with them because I mostly track my car. But they are rebuildable and worst case it's $300 per caliper.
Did you only swap the fronts?
👏🏼 approved!
Great video, thanks for review. Do you make some adjustments with master cylinder ?
thanks. No I did not change master cylinder.
2:48 fart
lol for sure dude!

Great video. Do you know by any chance if these clear the factory premium wheels?
given it clears factory 17'' wheels. I would believe so
Hello! My home track is Sonoma as well. I just bought an 86 and would like to do this install. Are all the parts in this video included in the kit?
The extended studs are not included. Other parts are in the brake kit.
were you able to reuse the dust shield without modifying it? the video seemed like you didn't need to but i wasn't sure i fyou did it before
No I did not need to modify the dust shields
So do you need the 15mm spacer to fit it or no? I’m thinking of doing this on the RPF1 18x9.5 38 for my car.
yes i need 15mm spacer, but my wheels are 17x9 ET45.
You might need a 3-5mm spacer. 3mm is the max I would do without new wheel studs.
nice informative vid. BTW, your brake bias calculator has a bug: ` var p_area = area(d1/2.) + area(d2/2.) + area(d3/2.); //inch ^2` should be ` var p_area = area(d1) + area(d2) + area(d3); //inch ^2`
Thanks for pointing that out. will fix that. but it won't affect the front/rear bias ratio:)
What size are the rpf1s?
What parts did you order?

how's the brake bias using the stage 2 kit with no rear kit?
What stage is that kit
Any bias or heat issues just swapping the fronts? Not sure if it's worth buying the rear kit from them too
I only had the front and had no issues with the bias.
hi, are the wheel spacers safe to install, like doesnt change handling much? do you have them in the rear too?
Safety is always one's own judgement after all. For me, it is safe as long as corresponding long studs are used. Using 15mm spacer on ET45 wheels are equivalent to using ET30 wheels in terms of suspension geometry. Yes scrub radius will change but no dramatic changes in handling for me.
@@TrackandBuild ok ty
Is there a Brembo or TRD BBK for the GR86? Do these fit under the stock 18 inch wheels without spacers?
Brembo has a GT BM4 kit that would fit this car. I also tested its template fitment in this video ruclips.net/video/oIKKfu1e5Bs/видео.html They are very wide so I doubt they will clear the OE wheels without spacers.
On GR86's any BBK that fit the first gen will bolt directly onto the second Gen. But The new BRZ uses a slightly revised setup preventing this.
I heard you've run into some issues with this setup. Will there be a follow-up video covering those?
Yes, there will be a follow up video about my deep review about this after 10 track days.
@@TrackandBuild where is it?
2:47 was that a fart?
surely it is lol
Can you tell me where you got those extended studs from?
the extended studs come with the HR 15mm spacers I use in the video.
@@TrackandBuild Thanks for that. Where did you get the middle sized studs which look to be for a 10mm spacer.
Where did you order the DBA rotors?
Any 2004 WRX STI rotor should work with this kit.
@@JFlogerzi I have an ISF and was wondering where to got the dba’s
@@Reflex702 what's the bolt pattern. They are typically dual drilled and you can get them directly from RR racing

Why not?
@@TrackandBuild because the cost dose not out way the benefits. Stock brakes with good pads and fluid is fine.
@@supradrift1000 well the benefits depend on the application really. OE caliper is fine on the street or for light track use.
overall how is this car? is it really as fun to drive as they say? also, would u say the power is too low?
This car is great for track out of the box. It's not a slow car considering its size and weight. basically the power level is on par with the S2000. It's a platform with great potential.
The Second Gen is a great track car to learn with. The new 2.4FA motor is a gem compared to the first gen FA20 :P

Does it has dust boot ? Tnx!
no it does not
Hey Thanks for the video. Is this kit specific to the 22 brz ? I heard the knuckles on the 22 brz are different size to previous gen so the previous gen caliper brackets Do not fit . You didn’t seem to have an issue
