Lug nut rule
Does anyone know what kind of rules the NHRA has on lug nuts? I've only raced with stock wheels and no one has ever said anything about them, but now I'm going to be racing the pickup this weekend and don't want to get turned away because of them.
Right now the studs don't extend quite all the way through the nut. It seems (from memory) that there either has to be a min of 1 thread showing, or thread engagement equivalent to the size of the stud (1/2" in my case). But I can't remember.
Thanks
