Following in the footsteps of Shelby and Galpin Auto Sports, Steeda has revealed a new widebody kit that can be fitted to the Mustang GT, Boss 302 and Shelby GT500. The package includes front and rear fenders that add six and seven inches respectively to the Stang's width to make room for 22-inch alloys, as well as a redesigned front fascia, a unique rear decklid and shaved door handles with electronic door opening mechanism. Without revealing how, Steeda claims it has also boosted power of the Shelby GT500 from 662 to 725 horsepower.
