why longer studs for wheel lug nuts?

[12lives]

I've seen many cars, usually street/strip cars, that have long wheel studs. This prevents the use of the factory chrome acorn lug nuts. Why do you do this?

to be sure you have enough nut engagement so you don't shear off a stud while racing (i.e. wheel comes off car!). Most sanctioning bodies require the long studs and open nuts to prove there is enough thread engagement

NHRA/IHRA rules. Open long shank nuts work fine and IMHO look kewl. Also, rubber valve stems are not allowed at the track.

Also to show off the 1/2" Studs in the Aftermarket Axles!:grin:

Cool - never having raced I didn't know. So is there a HP limit or et limit? what do the F.A.S.T. cars do?

Bill, I think NHRA tracks mandate aftermarket axles @ 11.99 ET.

I'm sure the F.A.S.T. cars could use them, but they'd have to disguise them somehow. Don't know for sure if they do use them or not.:Do No:

Someone can correct me if I am wrong. My car does not go below
14.0 and rubber valve stems are OK.
The studs have to go into the lug nut something like a 1/2 inch
Thick aluminum wheels do not allow the stock studs to go into the nut enough. Longer studs are needed and open ones are easy to prove it. This all probably changes the faster you go.

Also, I believe that with longer studs, if the nuts loosened you buy some time before the whole wheel/tire exits....
