Front Drag tires!????

Sounds like you're trying to go pretty low considering the 215/70 is tight. What style wheel are looking for? Something to match the rear wheels?

A 15x3.5 or 15x4 with a "VW" sized tire and something like a 1 3/4 or 1 7/8 backspace will clear just about anything. I've squeezed a 195/75 on a 4" wheel before, but I'm not sure it will clear with the setup you are looking at?
