l am thinking Black whit chrome lip FR500 is 18 x9 on the front and 18x10 Dip dish on the rear or same set up color on the bullit 17x9 on the front and 17 x 10.5 deep dish on the rear. which would look better?
i already have the stock 17x8 bullit that came with it.

Hey, if you can put Bullits on your car, do it (of course you can, it is a mustang!)

bullitts are always great looking, especially if you get them polished or chromed 18in.+

fr500 is look good with that color scheme also, but l really like bullitts the most out of any wheel on a mustang really.

l say get the deep dish bullitts all they way around, 9 is in front and 10 is in back. That gives it such a mean stance. If you do the 17x10.5, then the tire just does not look tall enough.

if your GT has been lowered consider 19'' Foose wheels (all chrome or
black/chrome):
