is your car lowered by any chance? on earlier years, lowering will put it on the extreme negative edge of the spec range, and that can cause the kind of wear you describe; I assume it is the same on S550 cars
did they give you the alignment sheet with the readings? if so, is it on the extreme negative end of the range for camber?
I'm pretty sure the alignment specs are the same for all of the Mustangs regardless of engine; but the weight of the engine can affect the alignment
also do you have the super-soft summer only tires? if yes, they don't last long
