I was running the 04 down stock Bullitt mustang wheels on mine for about 2 years but I just picked up a set of 05 up Bullitts about a month ago. both worked out great but the 05 ups have about another 5/8" extra offset to get the wheel more inside the fender. I was planning on comming down another inch or so in the futer so thats why I made the switch to the newer wheel.
