A few years ago, I put in a used 2900 RPS clutch. 6 puck clutch with a combination of the copper pads and normal organic pads. The previous owner had problems with it slipping so he sent it back and they resurfaced the flywheel and gave him a brand new clutch disk. I put it in my car at this point and drove it for a few years with no problems. I never launched it or beat on it, and most of the miles it saw were highway and track miles. All of ab sudden it started slipping while I was leaving a stoplight on my way to work last summer. I pulled the entire assembly thinking the same thing happened again this time to me, and the flywheel didn't measure way out of tolerance, but since I didn't want to deal with it I just bought an XTD stage 4 to throw in. I finally got around to putting in the XTD and I'm having the same slipping problem. This clutch has a 6 puck unsprung disk, all copper pads. It drives fine when not under load but as soon as I give it more gas, RPMs start to climb.
I checked the slave cylinder to make sure I could push the piston in by hand and I could, so that's not holding it up. The clutch fork is also a little loose (has play showing the springs aren't being held up on the clutch). The pedal adjustment seems fine and it engages about where it always has and there is free play at the top of the pedal travel.
What the heck am I missing here? Is it possible something else in the drive train is broken or something and it doesn't have any noise or other indication? The car also drives fine at speed as long as I'm not trying to accelerate.
Any suggestions?
