If you run slicks or drag radials the rearend will not last nearly as long as if you just use street tires. What are you planning on using?
If your car is an automatic, a good converter will be more beneficial than a gear change and you can keep the stock gears for better MPGs.

You're playing with fire either way, but an auto will last longer. I blew up a couple of 10 bolts with my six speed, but switched to an auto and ran several low 10 sec passes lifting the wheels before it broke again. The time in my sig was on a 10 bolt.

i think you will be alright for a while. i think people dont give them enough credit. sure they are a little weak, but they arent going to break just like that. you probably are getting close to pushing the full potential of it though. i say rip on ir for a while.

All the auto Guys say they are fine, its because they are auto, we M6 guys go through 10 bolts every oil change.

Mine has been fine on DRs with plenty of beating on. I have seen them tear up pretty easy when they have high mileage. I think that fresh rebuilds with new bearing sets helps the 10 bolt's longevity.
