Yep, custom fit exactly to our hubs... 20 thousandths clearance around the center bore to allow for your studs to be off a bit (and those are cut to 13mm instead of the 12mm they actually are... but that is only like a 40 thou difference in itself) and the overall hub diameter is matched exactly. The only thing I have not 100% confirmed is if the fit is as perfect on an MSP because of the different rotors, but the info I have indicates there shouldn't be any difference. If someone has one and gets these and isn't happy no questions asked on the return!
I have some 1/8", 1/4" and 1/16" coming, and can add some additional if needed. They just took the order today, and they will run it sometime next week, so I'm sure I can get more added if you guys need some over the weekend...
I'm working on the leadtimes on the ARP studs right now... I can get them but the lead might be like 2 weeks which sucks, so I might start having to stock some of them.
The lugs I'm trying to get are small diameter M12x1.5 60 degree conical seat lugs. They actually have some in "extra deep" that may allow you to keep a closed end over the bolts. But I'm also looking at the open end ones... roughly looksl ike a set of 20 will run around 25 or hopefully less.
