SRT unveiled the Viper GT3-R at Le Mans this week. This competition-only package is eligible to compete in FIA GT3, United SportsCar Racing GT Daytona, Pirelli World Challenge GT, NARRA and SCCA/NASA and can be yours for just $459,000. Which is chump change when you consider the fact that the engine, chassis, suspension, electronics and aerodynamics are practically right out of the GTS-R GTE class car in the 2013 24 Hours of Le Mans and the American Le Mans Series. The GT3-R is powered by the Viper V-10 race engine, which puts out 680-horsepower and 640-lb.-ft. of torque, and gears are shifted with a Xtrac 6-speed paddle shift. SRT is taking orders now for a late 2013 delivery.
