centerforce clutch

I had a problem with my Centerforce Dual Friction pressure plate too, years ago. I had one in a 70 Mustang that would run in the 10's and one day I cranked into it real good and collapsed the pressure plate. I had bought it from Summit and called them up. They said they hadn't ever gotten any feedback about a Centerforce Dual Friction pressure plate doing that. Like you, it had been in the car a while and it wasn't the installation. I got another set and didn't have that happen again. My only call was to Summit, maybe I should of researched it further.
