Subaru WRX (GD/GG, 2002-2007): Brakes mods
STI Brembo brake swap Reported
Community and vendor sources describe front Brembos bolting to the WRX with the right rotors, and rears needing an adapter bracket on 2002-05 cars plus a parking-brake solution. Grassroots notes WRX rotors get hard use on track.
Caveats: Brakes are safety-critical. All claims here are community-reported, not manufacturer-verified, and one source disagrees on difficulty. Follow a vendor's kit documentation.
Parts: 2004-2007 STI front Brembo calipers, 2004-2007 STI rear Brembo calipers, DBA 2657 rear adapter rotor
