Brembo 03-07 Cayenne/S/Turbo Rr GT BBK 4Pis Cast 380x28 2pc Rotor Slotted Type3-Silver

This is the Brembo Rear GT Big Brake Kit for your 2003-2007 Porsche Cayenne, Cayenne S, or Cayenne Turbo. If you're looking to significantly improve your braking performance, especially for spirited driving or towing, this kit is a solid choice. It replaces your factory rear brake setup with larger, more capable components designed to handle increased heat and stress.

At the heart of this kit are the 380x28mm two-piece rotors. The larger diameter helps dissipate heat more effectively, reducing the chance of brake fade during hard use. The two-piece design, with a cast iron friction ring bolted to an aluminum hat, helps manage thermal expansion and reduces overall weight compared to a solid one-piece rotor. These rotors feature Brembo's Type 3 slotting pattern, which is known for its effectiveness in clearing out dust and gas that can build up between the pad and rotor surface, ensuring consistent stopping power. The calipers are a 4-piston cast aluminum design, providing increased clamping force over the stock calipers for improved braking response.

This kit is designed as a direct fit for the specified Cayenne models, meaning it bolts on without requiring extensive modifications. You'll want to ensure you have the correct tools and follow the manufacturer's installation instructions carefully. Because this is a significant upgrade, it's a good idea to check the manufacturer's recommendations for any other supporting components or brake fluid that would best complement this high-performance brake system.
