This special rotor is designed for the 2002-2007 WRX that has been retrofitted with STi Brembo rear calipers. The outside is the diameter of the WRX STi 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 DBA Street-series rotors are heat-treated and feature DBA’s 6×6 “Wiper Slot” or “T-Slot” design.
Photo is representative; the rotors you get will look a little different in the center hat design.
Set of two brake rotors.
