Anything that does NOT have a FWD offset.
The new 05+ Mustang rims won't fit is what Jeremi was telling me. So...find rims that were on (or are on) any mustang year 1994 to 2006-07ish and you're set.
How many beers did you have when I have had supposedly said that ?
You cannot put all 05+ wheels into one category and expect them all to fit, or not for that matter. Stick to solid specs.
Mike, why 36mm ? Because it is
... but only for a 9" wide wheel.
max backspace in the front 6.5" for an 18" wheel, little less for a 17".
max backspace in the rear 7.5" for an 18" and larger wheel, less for a 17" due to sway bar interference.
How far they will stick out is a matter of preference. 3.5" of front space is somewhat flush with the body lines. Anything more starts to look odd, anything less looks too narrow. All IMO, and IME.
