The SRT^® Viper GT3-R is the direct descendent of the high performance GTS-R GTE class racer campaigned by SRT Motorsports in the 2013 24 Hours of Le Mans and the American Le Mans Series. Virtually all of the technology developed by the Chrysler Group for the factory GTS-Rs for engine, chassis, suspension, electronics and aerodynamics is infused into every Viper GT3-R. All of it. It’s your chance to get the knowledge of a factory race program in a 200 mph* striped package. The SRT Viper GT3-R builds upon the success of the GTS-R. The chassis has been equipped with a highly efficient aerodynamic package to optimize handling. Further racing enhancements include an Xtrac six-speed sequential transmission with paddle shifters, six-piston front brake calipers with four-piston rears, lightweight wheels and a multi-disc race clutch to help extract maximum performance from the V-10 engine.
