What Larry said...if you roam the pits you’ll note Stock Eliminator is about the only class you’ll even see many 1/2 inch studs. My car has a good 9 inch setup but surprisingly was built using the smaller studs, and after breaking two studs it was hard to even find some last weekend (thanks to Mike McMahan, the Valdosta r/u, for the loaners). Moser sells the whole 5/8 stud kit for $80 so is by far the way to go. Losing a rear slick is never a pretty picture.
