Shopper Award

The front bumper undertray is an exact replica of the original NSX-R plastic undertray. The undertray installs under the front bumper and lip spoiler, this tray is designed by Honda for the NSX-R. The purpose is to contain any air flow passage between the bottom of the car to the mouth of the front bumper openings. Reducing the turbulence by channeling air flow through will increase the airflow underneath the car. This will create a greater lower pressure area and enhance the downforce available without creating parasitic drag.

This product can be used by itself without the battery with optional brackets (not included). This product uses the factory lip spoiler mounting, if you have an aftermarket bumper, it will likely not be compatible with this product.
