Mustang rims don't pose too big of a problem using them on our cars if you're not lowered. If I recall, their rims typically have a 35 offset when ours more commonly use 45, so they stick out a little but not enough to ruin looks. I'm almost set on having a set of 17" Bullit rims with new center caps (don't want a horsey). I'd prefer 18" but haven't seen anything other than the 17" Ford offerings.
