It is more a choice between a kit that provides the best look per dollar and a kit that provides...

    A spoiler is intended to control the way the air streaming over the car is affecting the rear of the vehicle. Spoilers cause drag, and actually slow the car down or make it unstable, if not properly designed. A correctly designed spoiler can counteract the lifting forces that most cars experience when speeds get high, and keep the car on the road.

    High quality carbon fiber. Fits good and looks good. Installation is pretty straightforward. Need some bolts and nuts to complete the installation. Otherwise, it was perfect.
