There is disclosed a conversion for a clutch of a motor vehicle which uses a conventional Belleville spring to bias a pressure plate and clamp a clutch disc between the pressure plate and the flywheel of the vehicle. In this invention, the frictional linings of the conventional clutch are substituted by frictional linings which are preferably located at optimum geometric spacing, and which have from 30-70 percent less surface area for frictional engagement than that conventionally furnished with the clutch. The invention is particularly applicable to upgraded performance cars, e.g., the new line of SLP cars being introduced by some manufacturers.
