And if much downforce is added, then at 200+ MPH, there would be a lot more load on the suspension and that'd have to be re-engineered also. Right? BTW what is the stock spring rates on the the GT?
I agree with not fooling with the manufacturers engineering, look at how many GT's have been ruined by altering boost, tuning, tire size, tire manufacturer, wheel size, wheel manufacturer. Some have actually changed spark plug heat range and gap. I guess we're lucky Ford hasn't come and taken away our cars. Car enthusiasts have proven over the years they are incapable of modifying cars, just look at all the damage Shelby has done. Imagine putting such a big engine in such a little car, insanity.
