Track-day junkies can finally get their hands on a street-legal racing version of the Viper to drive to the course�because railering is just so unccool. The Viper SRT10 ACR�s prodigiously powerful 600-hp engine remains unchanged from the standard, but the suspension is hardened up to improve the Viper�s already impeccable racetrack manners.
StopTech provides lightweight, two-piece vented rotors for sustained racetrack braking performance. The exterior package includes hinged front splitters, an adjustable rear wing and a sporty hood stripe. New wheels, featuring track-ready Michelin Sport Pilot tires, trim a good 40 pounds from the Viper. The Hard Core package replaces most of the upholstery in the interior with carbon fiber and substitutes a lap timer for the radio, saving 40 more pounds. Dodge says the ACR will be available late next spring for under $100,000�but not very far under, we�re guessing. �Mike Allen
