Did you ever go through tech and they stick a pen or something in your lugs? What are they doing? They are checking for proper stud length. They will 1st take a measurement to determine width of the threaded hole by holding their thumbnail to mark the pen or whatever of the width. Then they should stick it in the hole, if the pen bottoms out before the thumbnail touches nut , You pass! If the pen lets the thumbnail touch before bottoming out , it's time for longer studs.Tip; When buying new studs, don't get the Bellbottom grabbers, ya know when you walk by they reachout and grab pants leg, most speed shops carry longer studs , but they are usually the real long ones. Just order the length you need, because anything longer than what you need is overkill! I've told racers they need longer studs and the following week they come back with 6" studs in front. When asked why, I alway got the same answer "thats all they had at the speed shop"....Safety 1st....

A discussion of lugs and nuts just isn't the same if half-inch stud isn't even mentioned.......

It's true, when talking about studs to short, it goes without mentioning,

The safest (from a hardware and inspection standpoint) is for the stud to exit the end of the lug nut by some small amount. This removes any doubt and does not put you at the mercy of an over zealous inspector. Or am I the only one who ever saw that happen?

I think its supposed to be "out" by the same length as its diameter. In other words, if you have 1/2" studs, they must protrude 1/2" past the lug nut.
I may be mistaken. Chance favors the prepared mind. |

Wrong! If we are talking NHRA racing.. This test tells the inspector that the lugs protrude through the wheel the distance of the width of the lug stud. An NHRA mininum... Anything beyond that is totally up to the racer. See picture on pg.211, sect. 5.2, NHRA Bible 2003 and quote it to that over zealous (if you can find one) tech inspector.

Only one overzealuos tech I've ever run into was at E-town. They call him robo-tech!
I've never had anyone even look at my studs, but its good to know what the deal is. Especially when most folks are still running C-clips.  Chance favors the prepared mind. |

What are the rules on the studs/nuts of the front wheels, particularly if running 9.99 or quicker? Should I get longer studs that protrude through the open nuts like my rears do?

OK - With a street/strip 4 sp. car using slicks, running in the 12's is it ok to just use stock length studs and nuts with vette Rally rims? I'm also running C-clip eliminators. If I use DOT Drag Radials is this even an issue?

I don't know legally if it's OK. My guess is that tech won't give you a hard time, HOWEVER, I wouldn't run that combination as the four speed will hit the tires, and consequently the studs, extra hard. Could be scary.

Stock length studs are fine as long as they protrude through the rim at least the width of the stud. 6567 don't see an issue here. Unless you can prove to me that same size aftermarket high $ studs are better than stock. "I'm running stock till I break em". If you have to have aftermarket long studs, don't get them too long, this may be more of a hassle than help!..Havn't seen a 12" deep socket yet...

Thanks Tikiklub. The problem is that my street rims (Torque Thrust II's) use a closed nut. I could've probably found lug nuts that would have worked with longer studs and the mags but got lazy and went with stock length studs. The guy that I had do my rear end work is an old drag racer and he knew my intended use so I trust the quality of stud he used.
Bruce - I hear you and have thought about that - a lot! I'm hoping the few times I go to the track will make my odds better. (famous last words) http://home.earthlink.net/~uptons1/

Tech tip; When running closed lug nuts you can pull one off ea. rim and drive to tech for inspection, If they miss the fact that you don't have all your lugnuts, they are not going to check stud length. If they do catch missing nuts, pull them out of your pocket and say, I took them off for inspection. This burns em up, but its their fault. If we don't keep our race cars up to snuff, nobody else will....Safety 1st...

Ahem,
I go by coarse stud/nut engagement of 3-full thread turns...fine stud/nut engagement of 6 full thread turns...that's all you need for full fastner capability. Seems, if that is good enough for Mil-hardware, then having evidence of rear axle stud protruding even just a half-turn above the axle nut ought to be proof of holding capacity. My rear axle fastners (5 or 8 of them) are always... Half-Inch Studs

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
