NHRA rules state that your wheel stud needs to stick out from the wheel as far as it's diameter... so a 12mm stud needs to stick out 12mm from the surface of the wheel. I run 12mm 3" pressed-in wheel studs on my car... front I took the rotors off and beat the studs in with a big hammer. Rear I "pressed" them in using a lug nut and a huge breaker bar
