I was wondering if anyone has any suggestions on what backspace to use, this is on a 90 mustang. I already searched the forums and found nothing. I plan on going with the bulletts from American Muscle that has a 5.72 b.s. and a 30 mm offset up front. Also does any of you fox body owners have 17 by 8's up front with coilovers? If so whats your brake setup and how much b.s. do you have?
