Mazda Miata NB (99-05) Aluminum Undertray

The LRB Speed NB (’98-’05) Miata Undertray is CNC laser cut from 0.080″ (2mm) aluminum and it will stand up to all the road can throw at it!

The main undertray replaces the stock plastic Miata piece that is typically missing or damaged on most cars. It stretches from the front bumper skin mounting bracket to the subframe and it has uprights that attach to the frame rails. Not only does it look great, it also adds rigidity and support to the front bumper, as well as smoothing air flow underneath the car.

The front side pieces follow the curve of the front bumper and further spread the smoothed flat surface of the undertray!  As a bonus, bumper rigidity is even further improved.

The rear aero undertray stretches from the front of the subframe to the rear of the subframe beneath the oil pan for added protection and smoother airflow.

All mounting fasteners are included, in addition to installation instructions. If you have any further questions please write us! Thanks!
