I'm presently using the ARP 2.5" studs (metric) on my front hubs to mount my front skinnies (Centerline Warriors). I have to use a 1/4" spacer to clear my caliper and would like to have a longer stud. Anybody know of a metric stud that fits our hubs that's longer?

 

I picked up some 2 3/4' at PEP boys last year.

 

GM Performance Parts and Lingenfelter sell 2.67" 12mm studs with the correct knurl. I run them on the front, with Weld Pro-Stars and a 5/16" spacer. They will just barely pass tech (12mm of thread engagement in the hex portion of the lug). These studs are actually more than 3" long, but the last 1/2 inch is not threaded, to help you fit the wheel over the lugs. But they stick out of the end of the lugs, to the tech guys accept them, even though if you stuck a mic down in the opening, the threads would just barely make it.

 

Thanks for the input guys. I guess the other option would be to switch to a SAE diameter & thread, like a 1/2 stud...has anybody done this and would a stud with the correct knurl size?

 

That, metric to SAE with the same knurl size, I couldn't find but I was doing the run around town looking because I thought everyone would have longer studs. yeah right
