The D1 Racing Xtreme FRX400 clutch kit utilizes an extreme clamp load pressure plate paired with a 6-puck spung-hub clutch disc. This is an excellent solution for high horsepower vehicles looking for a quick clutch engagement and hard launch--perfect for drag racing and hard track use. The ceramic material is lightweight and has, on average, a coefficient of friction 28% higher than that of organic discs. The Xtreme pressure plate has a higher clamp load than our Performance series, resulting in even higher torque capacity. We recommend a 1000–KM break–in period.
