The front bumper tray is constructed of handlaid fiberglass. The tray is finished in a dark gel coating so that it can be painted if the owner wishes to do so. The Downforce under tray and battery tray work in conjunction to completely seal up the front under paneling of the car to reduce turbulence and channel a smoother passage of air. The purpose is to contain any airflow passage between the bottom of the car to the mouth of the front bumper openings. This will create a greater lower pressure area and enhance the downforce available without creating parasitic drag.
