Hays street clutch discs are designed to provide clean, smooth engagement and provide a significant performance increase without sacrificing street ability. These discs feature organic friction material that is riveted to a Marcel backing, and a sprung center hub to absorb driveline torque, eliminating shock and vibration to ensure chatter-free engagement.One of the earliest clutch designs but still among the most popular, the Hays Borg & Beck Three Finger Street Clutches utilize 12 heavy-duty coil springs to exert maximum pressure on the disc. These pressure plates are assembled without roller assist to minimize pedal pressure at high RPM.
