Speedwing R-Wing™ is the thing. Its unique aerodynamic design not only adds down force to enhance traction and handling, but it also minimizes turbulence, smoothing the air as it flows over the car for better road control. Speedwing™ installs quickly with built-in aluminum threaded fasteners and stainless steel installation hardware and adjustable threaded rods. Speedwing™ is available for 1979 to 2001 models. It is similar to the Cobra R wing style. Can be ordered in 9" street height or 11" race height (custom heights from 4.5" to 12" are available at an additional charge). 7% sales tax is added for Florida orders.
