Went to a PCA time trial yesterday. Got a good number of time trial runs in. on my last session I noticed shifting into fourth was a bit notchy. Then later I had trouble even getting it into 4th, once I even ground the gears pretty good.
Then after my last run I pulled off to run down the road for a cool down and I heard some strange noises as I was down shifting into 2nd while having trouble w/ the shift. When I stopped and tried to go into first it wouldn't go into gear, it wasn't disengaging the clutch. 2nd wasn't much better. I could turn the car off and put it in 1st, put the clutch in, and then start it. Trying to slip the clutch made a horrible noise and the car had very little power. After much trial and tribulation I finally limped it home. 200 mile trip pulling my tire trailer from mineral wells to austin. good thing I learned clutchless shifting in my a friends POS Aspire. After this I am seriously looking into getting a tow vehicle. I was quoted $450+ tow esimates!
Anyway, the sheet metal center section of the spring hub disc hand torn. I think some debris also got between the disc and pressureplate/flywheel causing disengagement problems

flywheel & pressure plate both quite a bit of heat spotting. 30K miles of hard auto-x and some time trials and lapping sessions thrown in.

Anyone know the minimum spec thickness for an LT1 flywheel after resurfacing?

Sorry to hear about your bad luck. I dunno what the min thickness is for it, but I know stock is around 1.828". Just take it to a shop and if they say its to thin then get another one. Given the milage and the use that its going to go though I would probably just get another one just to make sure its the proper thickness and you don't run into clutch slipage. This could also be someones way of telling you to park the z28 for awhile and race the yeller beast. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif)
