Any word on the front tires?
I might take the plunge this weekend and order a set, and check the back spacing a couple different ways. If it turns out they won't fit the Camaro, I'll put them on another car here.
Incidentally I was searching around and found that Weld Wheels measures the backspacing just how I originally described. Video here, fast forward to 3 minutes and skip the mumbo jumbo.

Has me thinking.....how is American Racing doing it? Because Weld is doing it from the very back lip of the wheel, like I mentioned earlier. I believe that is the standardized way. Measuring from the bead set gives me the confidence that the wheel is the same as a 15x7 rally (~3.75" from the bead), but what are they doing?
