Re: 15\" rim on a d60?
We've used Stockton Wheel's 15" with 3" of backspacing steels on a GM D60 with minor SANDING of the caliper. This is with a power wheel, not by hand, but total removal was less than 1/8" Pretty easy to do. I've seen wheels that took some major material removal to fit and I don't like that idea, breaking a caliper would be bad.
no experience with anything else
