Organic disc Newly developed asbestos-free friction is used. High thermal resistance and high burst resistance characteristics. No steel is required, which can cause high rpm blockage and/or synchro damage. Superior in shift operations and half-engagement feel, this clutch disc is recommended for any sporty/performance use. Clutch cover These clutch covers are designed to achieve a clamping load of approx. 40% higher than the original part allowing a greater torque transmission capacity. Ductile material is used for all pressure plates and high burst resistance can be achieved in all temperature ranges
