The Brembo Big Brake Kit for 2008–2014 Subaru WRX and 2015–2021 WRX applications is a front GTS upgrade that pairs cast six-piston calipers with 355×32 mm two-piece drilled rotors finished in black. The drilled two-piece rotors and six-piston calipers improve heat dissipation and offer a firmer, more consistent pedal feel than stock brakes to reduce fade during aggressive driving while remaining intended for direct front replacement.
