Not runnig a VW, but I can add that I'm a believer in stock clutch parts. The only part that might be problematic is the clutch lining coming off the disc. High RPM and a riveted lining will sometimes cause fractures at the rivet points. You can identify this fracture by the visible rivet holes in the lining particles left after disassembly.

A relatively cheap solution for this problem is to have it bonded to the disc by a clutch re-manufacturer. Bonding provides extensive contact area without stressing the specific contact points (rivet locations), and will last the life of the car, provided you don't slip the clutch constantly.

Just offering a new idea.

Good racing,

Bill
