The Brembo Rear GT big brake kit for 2011–2018 Cayenne Turbo applications combines four-piston cast calipers with 380×28 mm two-piece rotors to upgrade rear braking. Finished in red with drilled rotors, the kit is specified as a rear direct-fit option, offering enhanced rotor ventilation and a more robust rear braking assembly compared with many factory components.
