Is there an exact fit wheel stud that I can order from Jeg's or Summit? I have stock 26 spline axles (for now) with rear disc brakes. I'll need studs that are the same thread. I am using the stock GTA crosslace wheels with Mickey Thompson ET Streets. Any suggestions? Track rules require longer wheel studs for cars that run 11.99 and quicker.

 

There's nothing in the rulebook saying all cars must have longer studs. You only need longer studs if you use aftermarket rims that have a thick center section such as Weld Drag Lites.

The rules state that the stud must protrude into the hex portion of the nut at least the thickness of the stud.

Your 12mm studs must extend at least 12mm into the nut (not including the tapered part of the nut)

 

You'll need a lot more than that anyway to run in the 11's.

Minimum 5 point (everyone does the extra bar for a 6 point) roll bar. Single layer fire jacket. 5 point harness. If the tires are tubeless, they must have metal screw in valve stems. An SFI rated harmonic balancer. These are all the extras needed for your car to go into the 11's.

Aftermarket axles and a positive axle retention device (Ford 9", c-clip eliminators, rear disk brakes) are required at 10.99 but you should have them at 11.99 just to be safe.
