I have the CC Iron man clutch in my car for the last two years. It is an ACT heavy duty PP with a 6 puck sintered Iron sprung disk. It has held my 500 hp, 470 tq easilly. The pedal feel is awsome, being just a little stiffer than stock and it engages nicely. It doesnt like to be slipped much, when you slip it, like going up a steep drive way you can hear that its an agressive clutch compound and probably making a mess of the flywheel. Recently I had to make a U turn on a wet road, so I did a half donut, right after I pushed the clutch in and it didnt dissengage.........ya great, it welded the disk to the flywheel. After a minuite of thinking, I shut the car off and restarted it and luckily that was enough to pop it loose again. It shifted a little rough for about an hour afterwards, but now "seems" to be fine. I will find out soon what happened and how badly the PP and flywheel are damaged when I pull it apart.
my 2 cents.
