The hood was made of fiberglass to save weight and the Le Mans stripes added some style. A separate wide body conversion with the option of rear-only or full all-around wide body wheel arches was also available to spice up the exterior of the 2014 Shelby GT. Among other accessories, Shelby GT front fascia, carbon laminated hood louvers, billet upper grille with Ford running pony emblem and "Powered by Ford" badges on the sides completed the exterior package.
