Are these ARP studs (#100-7708) longer than the factory GM Camaro/Firebird studs?

The ARP's are more expensive and have to be ordered, where as the stock Camaro studs are in stock and only $1.19 a piece.

ARP says their stud is 2.5" measuring from the back of the hub to the end of the threads. Just wondering if anyone knows if stock Camaro studs are this same size or at least longer than the stock RX-7's? I am fitting some different wheels onto my RX and need some longer studs so I can fit a spacer.

I called ARP and they had no way to tell. Thanks

I just called a local Murrays/Oreillys store and had them measure their Dorman brand wheels stud which is a stock replacement for a 01 Camaro 5.7l and he said just the threads measure 3" long and from tip of thread to where the stud would hit the hub is 4" long. So it seems like the Dorman stud is actually longer than the ARP? Does that sound right?

The part number he gave me was 98498

there are two camaro studs from ARP- 2.5" and 3.25"
chances are the front and rear studs are different legnths, and the Dorman guy may have only measured one of them.

on my fc i used the 2.5 inch studs up front with a 10mm spacer and 50mm extended lugs. They worked great.
