I need to swap out my wheel studs for some longer ones to accomodate some wheels and spacers that I will be mounting for autocross. I am prepared to purchace the ARP wheel studs (100-7708) which are 2.5" long. The stocks are only 1" long. I only need about another half inch of thread for the replacements.

The ARP studs look like they are for a variety of GM vehicles, but doesn't list the applications. I was wondering if anyone knows if I could swap to different GM studs from a different car, that may be long enough?

Maybe you could go down to Discount Auto and look through their wheel stud bin in the back. Regardless, be prepared to kiss your wheel bearings goodbye.
