The Brembo rear GT big brake kit for 2001–2004 Porsche 996 C4S applications features four-piston cast calipers and 380x28mm two-piece rotors. This Type1 slotted rotor version in silver is supplied as a direct-fit rear upgrade, replacing OE rear hardware with larger rotors and multi-piston calipers to support better heat dispersion and easier rotor replacement while keeping a silver finish.
