My first rection is that the spring that came out of the disc did the damage, but the question is why? Then I saw the last picture, and I'm wondering what the h*ll? Is there any marks on the flywheel from contact, or is that all from the spring? was there a problem where the pressure plate bolted to teh crank? or to the flywheel? When I pulled mine apart recently, I found that the fingers on the plate had been contacting the springs on the disc. I think I would have had a spring pop out if I had left it much longer, but it started slipping about 2 years/80/000km ago!
It was the 8v disc and 16v pressure plate clutch kit from TT. All new bolts and center plate for the push rod. I have a eurospec lightened flywheel.
Gasser flywheel, 16v PP, 8v clutch, should be golden. Brendan
