These special rotors are designed for the 2002-2007 WRX that has been retrofitted with STi Brembo rear calipers. The outside is the diameter of the WRX STi Brembo rotor. The inside is the diameter of the WRX parking brake mechanism.
Note that if you have a 2002-2005 WRX, you will also need a hardware kit to bolt up the rear STi calipers; find that whole kit (including these rotors) HERE.
These rotors will NOT fit the WRX STi. They will also NOT fit the WRX unless the car is using the STi Brembo rear calipers.
These KNS/DBA 4000-series rotors are heat-treated for durability, and are electro-coated black on the hub and edge for a smart appearance.
Set of two brake rotors.
Fits all 2002-2007 Subaru WRX and 1993-2001 GC with retrofitted rear Brembo brakes.
