Wheel stud tolerances question
Just got my new longer wheel studs for the 2001, (ARP100-7708) suposodly correct for all late Vettes and Camaros and others.
I noted some difference around the splined seating area as follows
New studs outer splines 12.9mm Old studs 12.6mm
New studs inner splines 12.54mm Old studs 12.42mm
Holes in hubs average around 12.35mm (difficult to read accurately)
Will these studs press in OK or will I need to ease the holes slightly? or do you think these tolerances are acceptable?
Thanks in advance
Mike.

My personal feeling is that there is nothing to worry about here. A press fit between a splined shaft and a hole is a totally different animal than a solid shaft and a hole. The splines will deform big time as they are pressed in. This allows the manufacturers a much wider tolerance on the hole. Measuring an old stud that's already deformed, you can expect it to be a little smaller than a new one. Besides, the difference is only about 11 thou at the worst. I would leave the holes alone and just press them in.

Thanks guys, my friends 50 ton press did not seem to care about tolerances, all studs successfully fitted and the car is back on the road, thanks for your comments
