ARP studs and extended aluminum lug nuts?
I am about to install a new set of SKF wheel bearings, and I thought it might be worthwhile to go with ARP wheel studs. Then, because the ARP studs are longer than stock, I thought I'm going to need to get some extended and/or open ended lug nuts. So I cam across these:

Anyone have any experience? I know the weight savings isn't that much, but why not, esp since I'm going to have to get another set of lug nuts anyway. Plus they're black, so that might look nice on my black anodized CCW's.

These seem to be okay. I put anti-seize on the threads. Keep the threads clean, or they kind of bind up.

Those 949 ones look like they're the way to go, my buddy uses them and they work well. They are aluminum, so I'd expect to use a slightly lower torque spec than what's called for in the manual, but then again they have way more thread engagement, especially with the extended ARP studs. But then, if I use anti seize, that lowers the torque spec too. Any ideas what torque spec I should use if I'm using extended Al lug nuts with anti seize? This website http://www.futek.com/boltcalc.aspx?mode=metric indicates that for a "dry" stud with a k-factor of 0.2, recommended torque is 80 lb-ft and maximum torque is 106 lb-ft. When using moly anti-seize with a k-factor of 0.11, recommended torque settings decrease to 44 lb-ft, with a maximum torque of 59 lb-ft. Sounds a little low to me... maybe anti-seize isn't the way to go on the wheel lugs?

As pointed out by Steve I have been using the 949 Racing lug nuts for three seasons now. Like the steel ones I replace them annually just to prevent problems with thread fatigue. I have never had thread problems with the aluminum ones, but I have with the traditional steel acorn nuts.
I torque 90 ft lbs and a couple of times per year I will lightly spritz the ARPs with silicon spray. It all works great for me and I change wheels as much as anybody I would presume.
