Thanks for following up!

Another example showing they fit. Looks great.

I got mine and they do indeed fit and look great. Clearance is about 3.0-3.25mm at the closest point on PP Brembos.

Nice rotors btw. Are those girodiscs?

Yep. Girodisc 2pc front and rear. They are incredibly light compared to stock. Between the wheels, tires, and brake discs I lost about 11lb of rotating mass per corner.

Nice setup! Love the Girodisc rotors! Do they make them in sizes for PP Brembos now or did they make you a custom set?

Ken at KNS brakes hooked me up. The rear rotors are from an STi application but they are dual drilled and work on the BRZ pp brembos. You do have to trim the metal backing plate of the outside pad to the contour of the pad face and the pad with the squeal tab must go on the inside. The front rotors are 6.0lb lighter per corner and the rear rotors are 5.3lb lighter per corner.

Can you share the part numbers for the rotors?
No customization was needed for the fronts?

Front giroA1-007
Rear giroA2-095

Fronts required no modifications

Awesome! Thanks for the info. This is on my list of planned mods.

I think this is the only matching front/rear 2-piece rotor setup available for the PP Brembos.

Can you clarify the pad mods? You had to create clearance for the pad backing plate to the rotor? (the parking brake "drum"?)

What is the rough cost - fronts are $800/pair? Rears are ?

Thanks.

$800 per pair. $1600 total.

I had to grind the steel plate to be flush with the pad material. This only has to be done on the outside pad (the one without squeal tab). The pad with the squeal tab goes on the inside and does not need to be trimmed.

Here is a pic of the procedure.
