Sidebar: What makes it an ACR?
Aerodynamics: The Viper ACR's aero modifications include a two-piece carbon-fiber front splitter, twin carbon-fiber dive planes, and a seven-position carbon-fiber rear wing. The front splitter resides mostly under the car; it's supported by stainless-steel cables and features a removable center section that provides roughly one-third of the available front downforce. Chrysler claims that maximum downforce at speed is ten times that of a standard Viper, or roughly 1000 pounds. It also states that the ACR's aero add-ons produce a favorable seven pounds of downforce for every pound of drag they create.
Chassis: The ACR's spring rates are double that of the base Viper. Ride height is adjustable, and adjustable KW shocks are fitted. Forged aluminum wheels cover Brembo calipers and StopTech rotors. Wider front tires-the rears are already the widest that Michelin makes-are standard, as is an enlarged front antiroll bar.
Trim: The ACR is available in five colors with a dizzying array of striping options (including a color-matched steering wheel band). The optional Hard Core package saves forty extra pounds by losing the radio, trunk carpeting, tire inflator, and underhood mat. It also includes a USB-compatible lap timer with its own beacon.
