The Brembo GT big brake kit for 2004–2017 WRX STI applications pairs a six-piston cast caliper with a 355x32 mm two-piece drilled rotor as a front upgrade. Finished in red, this kit replaces factory front hardware with drilled two-piece rotors and high-capacity calipers to deliver firmer pedal feedback and a rotor construction suited to frequent high-load braking in performance driving scenarios.
