I know the 99-04 Mustangs had more outward wheel offset than the 05-09. [about an inch]
What about the pre-99 cars. Additional offset or about the same as 99-04?

From the 2008 FRPP catalog, it doesn't seem to vary by year quite like that. Some wheels listed for 99-04 are +30, others for 94-04 are more like +22. "R" wheels for the Fox seem to list +15.


You're probably going to be best off to measure clearances to the strut and do a little math on your own - and as a general note the overall width of a wheel is 1" wider than the advertised width, so a wheel listed at 8" wide with zero offset would have a backspacing of about 4.5" instead of the 4" that you might first think.
