The Beatrush Aluminum Underpanel improves your vehicles performance through three important aspects:

Handling - Underbody air turbulence is significantly reduced, thus producing a more stable ride at higher speeds. This also increases down force by creating a high velocity low pressure zone between the panel and road (less pressure underneath to push the car up).
Engine Temperature - Thanks to the low pressure zone heat is drawn out of the engine bay, thus reducing overall engine temps. Likewise, when the vehicle is in motion airflow through the engine bay is streamlined out into the high velocity airflow underneath.
Engine Protection - For competition or street use the underpanel prevents debris from entering the engine bay (aluminum > cheap plastic)

Highly Recommended Beatrush Product

If you're like me that lost their stock underplastic pieces and need to replace it. I highly recommend getting this piece instead. Much cheaper than the plastic oem pieces and way better with added security and aerodynamics. Amazingly my air temperatures have dropped and car feels more stable. Highly recommended mod.
