What is a performance clutch? What is a clutch kit? How does a performance clutch work? A performance clutch basically involves three changes over traditional organic clutches. This video features a Yonaka performance clutch kit. A performance clutch has a higher clamping force on the pressure plate (via the diaphragm spring). Performance clutches use different materials which can absorb less heat and that don't lose performance at higher temperatures. Finally, performance clutches use a "puck" design, 3 puck, 4 puck, 6 puck, which increase the pressure on the friction material, to prevent slip.
