I wouldn't do it, personally. The wheels being almost flush with the edge of the wheel well looks much better than tucked in underneath. Take a look at the rear end for example of this. Stock, the 94-98 Mustangs should have had a little longer axle in the rear so the wheels weren't so tucked in, IMO. Also, tucking the wheels in more may cause you to have to run rack limiters since you'd probably run into issues with tires rubbing at full-lock, or close to it. I think our cars could use a little more turning radius anyway, although I can get it to turn a little tighter by side-stepping the clutch if I'm really concerned about it
