I run draglites, same width on the front. I had to get the longest studs made in order to pass tech inspection at the track. With the spacer in there on stock studs, the lug nut hardly engages the stud. The stud barely makes it past the edge of the rim.

No offense, but you need to take some measurements if you haven't already. When I bolted my drag lites on and measured just how many threads were engaged, I wouldn't even drive it to the corner store until I got longer studs. BTW, drag lites use the same lug nuts.

I'm using closed ended lug nuts because they came with my wheels. I've heard that some race tracks require you to have open ended ones, but I haven't had any problems yet. Sorry, I don't have a part number.

Yep same here, but it isn't legal at the track. The stud must come out into the hex portion of the lug nut at least one full width of the stud itself. So basically on our cars it has to stick out past the rim about 1/2 to 3/4 of an inch, and they do check at some tracks. I had the tech guy take of the little plastic caps, and stick his pen down into the lug nut to show me how illegal it was.
