You mentioned different IFS widths. How wide will yours be hub to hub? Also, what size wheel and tire do you expect to fit in there? I am looking at a kit with a choice of 57 or 59 inches and think I want to go with the 59 inch width.
Good question! The CE website just says that their kit widens the track 2" over the original Mustang II. Various websites put the MII track at 56" so I'm gonna guess the CE kit puts it at about 58". Wheels and tires are still up in the air right now; I'm waiting for money to somehow materialize. Right now I have old camaro rims on there as rollers. Ideally I'm looking at 17x8 or so.
