Shop brake parts for the Subaru WRX STI 2004–2007 (GD chassis). The GD STI runs the EJ257 2.5L turbocharged flat-four and came standard with factory Brembo brakes — four-piston fixed calipers on 12.7 in front discs and two-piston fixed calipers on 12.3 in rear discs. You will find brake pads, rotors, calipers, big brake kits, stainless lines here — every part in this collection is fitment-tagged for the 2004–2007 WRX STI, so check your year and trim against the product fitment notes before ordering.
What brake parts fit my Subaru WRX STI 2004–2007 (GD chassis)?
Every brake part in this collection is fitment-tagged for the GD-chassis WRX STI (2004–2007) with the EJ257. The factory Brembo system was standard across the run, but trim still matters: the 2007 STI Limited used black Brembo calipers, so match parts to the Brembo setup your car has and confirm fitment on the product page before ordering.
Do I need Brembo-specific pads and rotors for my GD STI?
Yes — the STI came with a factory Brembo system, four-piston fixed front calipers on 12.7 in discs and two-piston fixed rear calipers on 12.3 in discs, so pads and rotors must be made for that caliper and disc combination rather than for a base WRX setup. Black calipers on a 2007 car mark it as a Limited; the colour is a trim identifier, so still order by the Brembo system and your model year.
