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.
