The rear window Vortex Generators were designed to swirl the air over the rear window, creating small vortices to keep the air tight over the back of the car. This vortex principle helps to direct more air to the rear wing, giving the car more down force and less drag. The concept of the Vortex Generators comes from the aircraft industry.

Included with the Vortex Generators are two fiberglass pieces that go over the front lower corners of the window, called window stays. The window stays keep the lower pressure air going over the rear window from lifting and spreading the window apart at speeds over 100mph. The Vortex Generators and Window Stays are both designed to improve driving at high speeds.
