I can't thank the guys at SPEC enough for rebuilding my clutch disc. The store where I had bought it from miss advertised it as a sprung hub, when in reality it was a rigid design. Took only about a week to get my disc back. Shipping it back to the store for a refund would have sucked. Here's a picture of the old and new clutch disc.
Instead of flexing, the plastic clip on the release bearing just sheared off when I put it in the clutch fork. Not sure if this was a defect, but the plastic seemed much more brittle than on the old one. I didn't want to take any chances on such a cheap part, so I called Downtown Porsche to pick up a replacement. The guy on the phone told me it would be $260 PLUS TAX! WTF?!?! The whole clutch kit cost me $620... At this point I decided that I'd rather keep my money. The old bearing was in pretty good condition, so I swapped out the plastic sleeve from that one. Not an ideal solution, but hopefully it will do. I did check the sleeve ID for wear and it was the same as the new one.
The tolerance on the SPEC splines seem to be much tighter than the OEM disc. Putting the transmission on was nearly impossible this time; we struggled for a couple of hours to get it on by hand. At first I thought we weren't getting it into the pilot bearing, but then I realised it was just the friction of the clutch disc splines (yes we did lube everything prior). Once we got some spline engagement, we put a few transmission bolts on and slowly tightened them diagonally. Each time I checked the gap using a vernier caliper to make sure the transmission was going in level.
