Wheel studs snapping at HPDE

Hey all, I have a 95 M3 that I run pretty hard at DE's, and have been running into issues with wheel studs on my left front wheel snapping, basically just sheering off in half. I run clockwise tracks, so left front sees the most stress. I use CCW track wheels, and run a 12mm spacer on the fronts. I also run full race tires so the car is seeing high g. Last June this happened the first time, I got back in from a session and noted a missing lug nut when I went to recheck torques, and noted the broken stud. Wrote it off to my tire installer over torquing the nut. One snapped again yesterday after I carefully torqued them all to 80 lb-ft. It's a little unsettling knowing the car is snapping them when all 5 are installed and occasionally ending up with only 4! The studs are 75mm in length, and came from reputable reseller (one of big two). They don't appear to be strong enough to handle track use. In any case I need to call the reseller today and find resolution.



Anyone else experienced this?
