08+ STI rear Brembo caliper and rotor question
Finally getting around to changing the rear calipers out for Brembo ones to match the fronts (CTSV Brembo Kit). I know that 08+ STI rear calipers are a direct bolt on to the BRZ hub, but I wanted to explore options for the rear rotors. I've seen a couple threads where STI rotors are redrilled to 5x100, but would the OEM performance package rear rotors from 17+ cars be a viable option or are they too small? Thanks for any input.

From a quick search I believe the standard rear rotor is 290mm and the PP rear rotor is 316mm. No idea how that would fit in your application.

The centric part number you want is: 125.47043, this is the PP specific rotor, with the correct bolt circle: 5x100
The one TwinFTW listed is for 5x114. Another option is from DBA rotors, the part number is: DBA 42656-10, these are dual drilled though.

Carid and Rock Auto are the only places I could fine these PP rotors without paying an arm and a leg for the oem ones
