Outside of a complete suspension mod from coils to bushings, new headers, brakes, wheels, and exhaust, the powertrain on this 2015 Mustang GT is pretty much stock. So it's a nice surprise when the Pony proves a lot quicker than one would expect, not to mention displays its superb handling on tight, shifty mountain passes like it does in this video. It may be a track-build at heart, but it's still a Mustang, and Mustangs ride free.
