The 10 bolt can last at the track if you load up the ring and pinion and bog it out of the hole, if you sidestep it from any rpm over 2000 and hook, its a goner. The pinion isn't supported from the rear like 9" and deflects from the ring gear in high HP applications, causing chipped teeth. I put about 200 passes with 1.79-1.9 second 60s on the stock 10 bolt, albeit with bias plys and 3200lbs race weight. Just don't sidestep it, don't let 1 tire go through the waterbox and the other stay dry, and just avoid any situation where both tires are not on equal traction surfaces, like 1 in the sand crap on the edge of the road and the other on dry pavement, or 1 tire on the line in the road.
My stock replacement clutch came from my buddy at a GM dealer for their price of $320 no markup. My buddy got the autozone one with only 4 springs and it held fine on his stock full weight car. Had I known how cheap a competition clutch stage 2.5 was, I would have bought that, but I was in a rush and this was 9 years ago. If you search you can find the CC 2.5 for $265 shipped brand new.
