Do you still have to have the wheel stud showing throught he lug nut on the front like you do on the back or can you use a closed ended shank on front? Thanks

I may be wrong but I thought the rule read"must have the thickness of the stud into the head of the lug nut
Correct.

Closed end lug nuts are fine as long as they're threaded on at least the thickness of the stud.

I run closed end lug nuts on my car.

I've never heard that before. Every car at the track here (not the street cars) must have open-end lug nuts, with apparently, the full thickness of the stud past the top of the nut.

my car will be a street/strip car but I am going with the open end just to be safe. I will be running slicks at the track and the car really will be more of a drag car anyway. thanks for the info guys

While the rule book does not specifically state open- or closed-end, the tech inspectors need to visually confirm the thread engagement spec, so if you are running a closed-end lug nut, the tech inspectors can fail you since the he/she cannot confirm the thread engagement. It's best to use open-end lug nuts.

Wrong.
With stock wheels it's not usually an issue-the problem is with an aftermarket wheel that is much thicker and you have very little thread going into the center section. They want to see how far the stud protrudes into the wheel, and as Vince mentioned, can and will boot you if they can't verify the facts.

if your using 7/16s front wheel studs they must protrude into the hex head portion of the lug 7/16s same with the rears. and yes most tech inspectors will boot you if you have closed ended lugnuts :yes:
