The Brembo rear GT big brake kit for 2011–2018 Porsche Cayenne Turbo models combines four-piston cast calipers with 380x28mm two-piece rotors. This version uses drilled rotors and a black finish, offering improved rotor serviceability and visible upgraded hardware. It’s specified as a direct-fit rear brake upgrade that replaces OE rear components with larger rotors and multi-piston calipers.
