Brembo 11-18 Cayenne/S/GTS Rear GT BBK 4 Piston Cast 380x28 2pc Rotor Slotted Type1-Red

The 380x28mm two-piece rotors in this Brembo GT Big Brake Kit are cast iron, chosen for their ability to handle heat and provide a solid foundation for braking performance. This kit is specifically for the rear of your 2011-2018 Porsche Cayenne, Cayenne S, or Cayenne GTS, and it brings a significant upgrade over the factory setup. The four-piston calipers are a key component, offering more clamping force and better pad distribution across the rotor surface compared to smaller, single-piston designs.

Brembo's GT Big Brake Kits are well-known for their ability to handle demanding driving conditions. The slotted rotor design helps to sweep away dust and gas that can build up between the pad and rotor, which helps maintain consistent braking performance, especially during repeated hard stops. The two-piece rotor construction allows for better thermal management, as the aluminum hat can dissipate heat more effectively than a solid, one-piece rotor. This also helps reduce rotational weight slightly compared to a full cast iron rotor of the same size.

When installing this kit, you're looking at a substantial improvement in your vehicle's stopping capability. The larger rotor surface area and the multi-piston caliper work together to shorten stopping distances and reduce brake fade. This kit is designed to be a direct replacement for the rear braking system, but it's always a good idea to consult the manufacturer's installation guide for specific details and torque specifications. You'll want to ensure you have the right tools and potentially a helper, as working on brake systems requires careful attention to detail.
