Replace those "puny" stock wheel studs with these "super-strength" oversized wheel studs. Overall length is 3" and 1-3/4"thread length.
This particular wheel stud is perfect for the front discs on your circle track GM car. Most sanctioning bodies require 5/8 studs for racing, and these are more than adequate. Hammer out your old wimpy studs, use Speedway's oversize stud drill bit to enlarge the hole, then install these. TIP: You may need to grind a bit off the head of these studs for them to fit perfectly in your rotor. Test fit it first by installing the stud backwards in the recess to make sure it seats properly. TIP: You don't need a press to install these! Install the stud loosely in the rotor, then use an old 5/8 lug nut and your impact wrench to pull them into place, nice and square!
