The Viper ACR (American Club Racer) is a street-legal version of the all-new 2008 Viper coupe optimized for racing, with a functional aerodynamic body kit, special suspension tuning, lightweight wheels, tires and brake rotors that shave 40 lbs of weight, and an optional "Hard Core" kit that deletes the stereo and replaces other components to save a further 40 lbs.
