Downforce

By Roger Meiners

Want the ACR look and aero performance for your GEN III and GEN IV Viper? Mopar® has the actual ACR carbon fiber Wing and other ACR bits and pieces waiting for you in their Performance Catalog—and online at www.mopar.com. These aero parts offer not only bold aesthetics, but functional benefits on the track. The “Race” kits include a variable geometry “fanged” front splitter, an adjustable rear wing sculpted by CFD (Computational Fluid Dynamics) and optimized front dive planes to maximize downforce (up to 1,000 lbs.) and provide increased levels of lateral grip. These new aerodynamic devices are formed in high-performance autoclaved carbon-fiber.

The splitter and dive planes feature a clear-coated carbon-fiber weave. The front splitter includes three removable rub strips that provide protection and wear resistance. It also includes a track extension that replaces the center splitter rub strip for closed-circuit events and reduces overall drag and increases front downforce nearly one-third. Two part numbers, P5155265 and P5155272 are for “Off-Road Use Only” and require a coilover kit (P5155234) to resist high downforce conditions at high speeds. Another two part numbers, P5155273 and P5155274 (for the Viper Roadster) have shorter wings for street use.
