Evolution Motorsports is proud to introduce our Clubsport big brake upgrade for the Cayenne TT / Turbo S / S. Our direct replacement upgrade replaces the OEM 355 mm brakes with 2 piece 380mm rotors, larger calipers / pads, hardware, sensors and larger dust shields. This is a must for Cayennes with higher than stock power upgrades. Braking is improved by more than 15%, which is a significant difference on a 6500-pound truck.
