Product Description

Brembo 09.C988.21 is a premium rear rotor set engineered for the latest Porsche Cayenne and Cayenne Coupe platforms (9YA/9YB) equipped with iron rear brakes. The UV-coated hat and edges provide long-lasting corrosion protection and a clean appearance behind the wheels, while high-carbon cast iron and precision balancing help minimize noise and vibration.

With OE-equivalent geometry and vented construction, these rotors install directly without modification and deliver consistent pedal feel and thermal stability during repeated stops. They are designed specifically for vehicles with the 330x26 mm rear iron brake package and are not compatible with PSCB or PCCB systems. Verify your rotor size and PR code prior to purchase for a perfect fit.
