I think this may be the next special edition Mustang. They did a Bullitt and Mach 1 already. FRPP already has a 5.0 4v motor so how hard will it be to stuff it in there and put an IRS and in there. I think they would use IRS in a Boss Mustang since those cars were known on the road coarse. Mach 1 was more of a drag racer's car.
