The sprung ceramic range of kits have been developed for motorsport applications where a higher heat and torque capacity is required. These discs utilise a sprung hub that helps to reduce shock loading and are commonly used in track cars that retain the factory transmission.

At Xtreme Clutch, we strive to offer a variety of clutch options for each vehicle to ensure a clutch solution is available for every vehicle application. Whether you are modifying a road vehicle or building a race car from scratch, we have the clutch solution for you. Our upgrades are divided into different stages depending on the friction disc material and the number of friction discs.

Xtreme Performance upgrade kits are available with everything you need for a successful installation + accessories you may want to upgrade or replace while the gearbox is out of the vehicle.
