The LRB Speed NA (89-97) Miata Undertray is CNC plasma cut from 0.080 (2mm) aluminum with an even brushed finish and it will stand up to all the road can throw at it!

Note: Current lead time is 3 weeks. We appreciate your understanding as these are made to order products.

The main undertrayreplaces 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 subframeand ithas 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 new 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!

Additional:Front Side Pieces: You will have to drill 2 holes in your bumper (1 on each side) for these to mount, everything else uses stock mounting points and requires no modification.
Main Undertray: Weve recently re-designed this undertray to use the bolt-together method which isused in our RX-8, NC Miata, and FB RX-7 undertrays. Its a more robust design which eliminates any rattles that may occur from aftermarket or worn-out engine mounts.
*The new added aero pieces (front sides and rear undertray) have been designed towork with both the older style slotted main undertray or the new bolt-together main undertray!*

-This Undertray was designed around the stock factory front bumper. If you have an aftermarket bumper you may need to make adjustments/modifications for our undertray to fit properly!

*While our undertrays will give you added protection over the stock plastic undertray, we cannot be responsible for damage that may occur to our aluminum trays on lowered vehicles.*

**Our undertray is engineered to be installed as depicted in the instructions. Please be sure to use ALL fasteners and mounting points and follow instructions carefully. Failure to use all mounting points may result in damage to the undertray or your car which we cannot be responsible for.**
