The Brembo front big brake kit for 2004–2017 Subaru WRX STI fitment pairs a 6‑piston billet caliper with 355×32mm two‑piece drilled rotors in a nickel finish. Designed for sustained aggressive driving, the multi‑piston calipers and drilled two‑piece rotors improve thermal management and pad bite, helping maintain consistent braking performance through repeated heavy use.
