Ok, well i have a 07 redfire GT mustang, and i have Bullitt motorsports 20x8.5 and 20x10 deep dish wheels. But i want a more muscular look, so i am thinking of doing the same rims but doing them in 18's and the same staggard style. If i can keep these rims and just get springs to adjust stance, what other stuff can i get to adjust the stance. I have the Eibach pro-kit in right now. here is a pic...
