I ran an american power train clutch. It was a Kevlar single disc. It was a POS and they did not do anything regarding warranty. After 200 miles. The pedal was so hard I could not even drive it in traffic.

I replaced it with an Mcleod RST twin disc and had an issue with it slipping after 1500 miles. I sent it back for warranty and they said something was wrong with the disc. They warrantied the clutch and I upgraded to the RXT. Works great now. A little clutch chatter, but it holds great. 4100lbs car with 600hp 650 torque.

The Twin disc are expensive, have you looked at the Centerforce dual friction?
