Heh... Have you seen my old thread?

The 2 SPEC products that I had in my bellhousing BOTH failed, at different times. The one of the springs on the friction disk fell out at an auto-x event after crossing the line, I went from full boost (about 10 PSI at the time) to 0% throttle in a fraction of a second, near redline, while leaving it in gear. Maybe that had something to do with it, I'm not sure. The dislodged spring made it impossible for me to disengage the clutch, I was lucky a friend of mine had AAA which I used to get a free tow home. When I replaced the broken disk with a new ClutchMasters friction disk the pressure plate broke less than a week after I got it back together. Some people don't have any problems with SPEC stuff, but I think it's garbage.
