APR Performance Carbon Fiber Rear Diffuser Dodge Viper SRT-10 Roadster 03-10

The Dodge Viper is one of the most iconic American made cars in recent history. The body lines and performance are both staggering. Just like every other car, gains can be seen with addons from the aftermarket world. APR has developed a functional rear diffuser for the Viper SRT10 Roadster.

Rear diffusers work by smoothing the air out and allowing other aerodynamic parts to function better. In essence, the rear diffuser can improve downforce on the car which is required to keep this high horsepower monster under control.
