That sounds close to ARP 100-7701. Can you use ARP 100-7713? It's another GM stud, but is M12x1.5, has an L1 of 3.25", and no nose (L3). That should give you the length you need. The problem is that the knurl is larger and slightly longer (which might not be an issue on a prepared car).

 

I'm guessing that the knurl diameter being 0.020 larger than the hubs would mean needing to modify the hub, and I'd rather not do that. I got in touch with ARP today and found out they have a 'special parts' department. I'm waiting on a call back, but at least initially, it sounds like making the 10 studs that I need doesn't sound like a huge deal.

 

mind posting some pix of your current set up? just out of curiousty

 

This is the best I've got easy access to:

 

thank you good sir! what a badass looking car.

 

Found some better pics, though these are with the long (1.5in) lug nuts instead of the short ones that are half the length. The short ones come even with the end of the stud.





... still waiting to hear from ARP, so I left another message.

 

If they cant make you custom studs i think that GM one you suggest might be your last option. might be a small enough of a discrepancy .020 you might be able to over come that with some heat and air assistance.

ive never heard of the 2 you suggested. i have always used ARP for studs specially in my other cars. either way best of luck hope you find a solution.

EDIT

http://www.cb7tuner.com/vbb/showthread.php?t=171207 a review of BWR studs. thats the only one i found aside from honda tech install lol.

 

ARP quoted me $600-700 for a custom set, so that option is out. I may re-drill a set of hubs and try the 100-7713's for the GM's.

 

I found some Blox Racing studs too, but I have no experience with them.

 

interested to see how this plays out. keep us updated.
