Brembo 03-07 Cayenne/S/Turbo Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Drilled-Silver

This Brembo GT Big Brake Kit for the rear of your 2003-2007 Porsche Cayenne, Cayenne S, or Cayenne Turbo gives you a significant upgrade in stopping power. You'll receive a complete kit designed to replace your factory rear braking system with a more robust setup. This includes a pair of Brembo's 4-piston GT calipers, which are cast from aluminum for a good balance of strength and weight, along with a pair of 380x28mm two-piece rotors. These rotors are drilled to help with heat dissipation and are silver in color, complementing the calipers. This kit is engineered to provide a substantial improvement in braking performance, especially under demanding conditions.

The calipers in this kit are Brembo's well-known GT series, featuring a 4-piston design. This larger piston area allows for more even pressure distribution across the brake pad, leading to more consistent and powerful braking. The two-piece rotor construction is a notable feature; the cast iron friction ring is attached to an aluminum hat. This design helps to reduce unsprung weight and allows the rotor to expand and contract more freely with heat, which can help prevent warping and cracking over time. The 380x28mm size offers a larger surface area for heat absorption and a longer lever arm for increased braking torque. The drilled pattern on the rotors helps to vent gases and heat away from the pad surface, maintaining better performance during repeated hard stops.

Installing a Big Brake Kit like this is a significant undertaking, and it's recommended to have a qualified mechanic perform the installation to ensure everything is set up correctly. This kit is designed to be a direct replacement for the rear braking system on the specified Cayenne models, but it's always a good idea to consult the included installation instructions for any specific details or requirements. With Brembo's reputation for high-performance braking components, this kit is a solid option for Cayenne owners looking to enhance their vehicle's stopping capability for spirited driving or towing.
