FWIW...I've run my car w/ the same 1/2"-20 wheel studs for 13 years and never had a failure. The first 3 years were running mid 10s at 3700 lbs and then 10+ years of mid 9 sec passes at 3800 lbs.
I did finally upgrade to 5/8" studs last year after the car dipped into the 8s on nitrous. All the 1/2" studs are still straight. I think they are ARP but not sure...whatever Moser uses.
