04-07 and 08+ STI Brembo Caliper Differences.

Front:
Pretty much identical other than color and what is printed on the caliper.
- 04-07 is gold and says Brembo
- 08+ is black and says STI
- Both black and gold calipers will directly bolt up to ALMOST ALL front Subarus without modifications.

Rear:
Very different in terms of geometry of the calipers and offsets and mounting locations. As well as the colors.
- 04-07 is gold, has pistons that are 36mm in diameter, reads Brembo on the side.
- 08+ is black, has pistons that are 40mm in diameter, reads STI on the side.
- 04-07 calipers will fit on ALMOST all rear Subaru cars, older cars require our V1.1 Bracket, newer cars require our V2.0 bracket.
- 08+ calipers WILL NOT fit on the rear of older cars, they WILL fit on the newer cars WITHOUT modifications.
