It's a race car when you say it's a race car. They'll only throw you out once. I am not clear about drag radials and wheel studs. I'm pretty sure if you have racing slicks that the studs must show 2 threads through the nut. Also if these are racing drag radials I would recommend treating them like slicks. Axle studs and lug nuts are relatively inexpensive. If, according to tech, these radials are treated like slicks, you won't be able to run a Street or Sportsman class. Hope this helps a little.
