I have the ARP wheel studs, that are a good bit longer than stock (for spacers for slicks and such) and I need a longer/deeper wheel lock to protect my rims while daily driving. Anybody know where to find something like this?

any place that sells rims should have something for you. might take some trial and error unless someone else on here can give you specific information on what will fit properly

My rims came with gorilla locks -- and they don't have an end cap to them -- meaning -- the wheel stud could pass through the back if you wanted... try something like that.

Yes gorilla has the largest variety of lug nuts out of anyone, they have a catalog you can brose @ http://www.gorilla-auto.com/.

I have an idea if your really stuck and cant find something that fits. This might be a really strange idea.. but should work. since our cars are use 5 studs, why not just change 1 of the long studa back to stock length. This might be kinda weird looking, but you could get any lock then. And even if you put spavers on, 4 lugs should do you just fine.
Now, this is just an idea, if its not practical please dont flame. Its just an idea.

That would be a great idea, but wouldn't be NHRA legal, so if you wanted to run at a track, you probably wouldn't be able to creep past tech inspection.
Just something to consider.

ahh.. icic.. ok, Im not aware of those guidlines. I take back what I said then. :7

Open nut lug locks are the way to go. I'm only aware of gorilla carrying them.
