Street Legal: The 2008 Dodge Viper SRT10 ACR

The all-new, 600-horsepower, 2008 Dodge Viper SRT10 ACR (American Club Racer) is the latest addition to Chrysler LLC’s Street and Racing Technology (SRT) family that is engineered to dominate the race track. The Viper SRT10, which just made an appearance at the 2007 LA Auto Show, gives superb performance for under $100,000,


The 2008 Viper is specifically modified and tuned for track performance. The ACR suspension includes coil-over racing dampers from KW suspensions that are adjustable for damping and ride height. The shocks are two-way adjustable without removing the wheels–a time saver on the track–and they include a large range for compression and rebound. The KW dampers and forks are machined from solid aluminum billet, feature spherical bearing mounts, and are optimized to minimize wieght and maximize performance.

Lightweight forged aluminum Sidewinder wheels are optimized by using Finite Element Analysis to achieve a lower rotating unsprung mass. Finished in gloss black paint,they wear Michelin Pilot Sport Cup DOT-approved (street legal) race tires, providing enhanced grip on the track. StopTech two-piece, slotted, lightweight rotors combine with the Viper SRT10s Brembo calibers to reduce rotating inertia and unsprung mass, improve brake cooling, and significantly reduce fade even under extreme conditions.


The powertrain is the heart and soul of the Viper SRT10 ACR. The new 8.4-liter aluminum V-10 engine produces 600-horsepower and 560 lb-ft of torque with Computer Numerically Controlled (CNC)-shaped combustion chambers, large valves and Variable Valve Timing (VVT). The Viper SRT10 ACR also sports the latest evolution of the Tremec T56 six-speed manual transmission (TR6060) and power is transmitted to the rear wheels via a GKN ViscoLok speed-sensing limited-slip differential
