EXEDY cerametallic clutches are designed to handle the abuse of high power modified engines. EXEDY cerametallic friction material can handle much more slippage than stock type disc assemblies. EXEDY cerametallic clutch discs feature spring center dampers to reduce the impact and shock loads placed on the drive train. This protects the transmission and the entire drive line system. All EXEDY clutch discs are equipped with thin cerametallic friction material (approximately half the thickness of a stock disc). Compared to other clutch discs with thicker friction materials, EXEDY's thinner layer of friction material reduces clutch disc inertia and improves transmission shift efforts and synchronizer durability. As with any cerametallic clutch system, some compromise of startup drivability should be expected as compared to a stock clutch (i.e. chatter on light throttle, low rpm startup). This characteristic is considered generally acceptable in modified performance cars.
