The Brembo GTS front big brake kit covering 2002–2021 Subaru WRX models features cast six-piston calipers with 350 x 34 mm two-piece slotted Type 3 rotors in black. Designed as a broad upgrade across multiple model years, the larger diameter and slotted rotor face improve cooling and pad bite under heavy use. Two-piece rotors help control thermal expansion and simplify ring or hat replacement during maintenance.
