Ford GT500 owners can drop their car off in Vegas at Shelby's mod center where it will receive a host of visual & performance mods to make it even more powerful & exclusive than when it left the factory floor. Exterior mods include a carbon fiber lower front fascia splitter & mirror covers, a lighter aluminum hood with grille inserts, "Shelby" lettering on the rear deck, those cool sequential taillamps, front & rear brake ducts, special Anniversary striping for the convertible models, & those sharp 20-inch American Racing Shelby Razor wheels in black. The 40th Anniversary package also improves the GT500's performance with the addition of a Shelby Signature Borla exhaust that allows the Mustang's motor to exhale with less impedance. While Shelby didn't go so far as addressing the GT500's biggest fault, it's weight, it has added a more capable Eibach coilover suspension that's adjustable for street or strip, as well as larger anti-roll bars.
