Lyfe Motorsports builds some of the world's fastest vehicles that compete in time attack, Pike's Peak, among other forms of motorsports. With that being said, they know a few things about aerodynamics, and on this page, you are looking at the Lyfe Motorsports Diffuser.

This rear diffuser has been designed to increase the venturi effect to create a higher vacuum between the bottom of your car and the road at a high rate of speed. This improves the aerodynamics, downforce, as well as the stability. This is especially beneficial for those of you who participate in high-performance driving events such as weekend track days, or auto-x or any other event where speed will be reached.

This diffuser is made from quality steel materials and has been powder-coated in a nice satin black finish for extra protection against corrosion. This is a 3-piece diffuser that will come provided with all of the required hardware, and brackets to make it ready for the installation.
