^^^ Edited the above post to show correct information

The Subaru part number for the "correct" rear rotors (performance pack rotors on '17+ BRZ) is: 26700CA000


They're currently selling for ~$325 each which is hilarious.

I have the Centric parts replacement brake rotor for the front stage 2 Kit if anyone needs the part number

125.47019

Or 121.47019 for the Centric C-tek

Just thought I would mention to be aware of your wheel weights on close fitting wheels like 17x9+35 RPF1s. The caliper took the layer of tape off of my weights.

Does anybody have real world experience w/ street performance rear pad wear? I looked at the pad size and they're awfully small and thinner than OEM. Since the kit shifts the bias a lot to the rear when paired with the Stage 1-4 front kits, I'm wondering how bad the pad rate is.

Not a direct answer, but my car on stock calipers goes through front pads roughly twice as fast as rear pads, so I'd bet even if with the differences the worst case would be even front/rear wear rates.

The REAR ROTORS ARE NOT FROM A 2004 STI as stated on the website and in this thread. They are too wide and the inside of the rotor hits the backing plate before mounting to the hub. The correct rotors are from a 2008-2017 STI. However, if you purchase regular brand 08-17 STI rotors the bolt pattern will be wrong (5x114.3). DBA dual drills those rotors for 5x100 applications. DBA Part# 42656S-10.

The 2017+ 86/BRZ with the Performance Package has the correct rear rotors for this kit as well but are difficult to find as of writing this.

This information has been confirmed with RR-Racing

Do you happen to know the front/rear caliper model numbers? My right rear caliper is sticking and I need to replace it. Terribly uneven pad wear and a ton of brake dust on that side. I'd like to confirm the piston sizes and rotor thicknesses.


I also have the front Stage II and the rear Sport Performance. They're all black with Wilwood text - I'm assuming that's Wilwood's Bristol Matte Black w/ white logo, though I'd rather have it in their Gloss Black w/ white logo.

Hey there. It it were me, I would attempt to get the calipers rebuilt. But here is the info I have in my notes.

Front: Willwood Forged Superlite radial 6r calipers - 1.25" rotor width (90% sure of the rotor width)

Rear: Willwood powerlite radial mount calipers - I assume the rotor width is .86 and have no idea on the piston area.

I hope this helps a little but that is all I got. The RRRacing guys are pretty good at answering their emails. I had a 30 min phone conversation with them a few months ago.

Looks like the replacement rear Centric rotors (2017+ BRZ with Brembo) are now available on Rockauto. $54 bucks each.

They are Wilwoods.

I didn't realize it was a plate. I thought it was just painted like the wilwood is.

I didn't realize it was a plate either. I will have to take a look.

[maregt]

It's a plate glued on the caliper, behind the plate there is the wilwood logo
