My "new" '74 Duster- or why I need a project like a hole in the head
As awesome as that is...I have to admit that aluminum hubs for street use scare me.
Originally I had the same kind of thought. But honestly aluminum hubs and even aluminum steering knuckles are really common on modern cars. And those are cast aluminum hubs and knuckles, not billet.
So I put them right there in the same category as aluminum wheels, they get an occasional inspection. But as long as the studs aren't loose there really shouldn't be any issues. They're basically just copies of the factory hubs less the rotor, so should anything ever arise with them I can just have the rotors turned off of a factory set to replace them.
The Viper calipers on AR Engineering brackets with 12" B-body rotors WILL clear a 15" wheel.

You mean the 11.75" B/R body rotors. Yes, that's been known since the second go around with the Green Brick. That kit was for the later 73+ drum spindles and uses the Gen II Viper calipers.
I think we're all talking about the 13" Viper kit, which uses the 73+ disk spindles and the Get III Viper calipers. And which definitely won't fit on anything smaller than a 17" rim, and probably not a lot of 17" rims either. I think it would be safe to say the 13" Viper kit will probably work with most 18" wheels, and some 17" wheels, but probably not "all" in either diameter.
