Looking to get a set of drag rims for the rear of my Mach 1 but have a couple questions. Id like to run a 15" rim but not sure if I should go 8" wide or 10". I have 18x9 up front, would it be an issue running 8" in the rear? The reason for this is because an 8" would require minimal modifications to fit over the Mach 1 brakes where a 10" would require a little more but not an outrageous amount.
