The LRB Speed NB (’98-’05) Miata Undertray is CNC plasma 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 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!
Standard NB Main Undertray: We’ve recently re-designed this undertray to use the bolt-together method which is used in our RX-8, NA Miata, NC Miata, and FB RX-7 undertrays. It’s 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 to work with both the older style slotted main undertray or the new bolt-together main undertray!*
*All products are made to order in house by Landon and Rebecca, so we currently have a 15 business day (3 week) build time for standard Priority Mail orders. This is the worst case scenario and we usually ship out between 5-10 business days (1-2 weeks) after an order has been placed. If you need to receive your order sooner, please either check out with Priority Mail Express shipping or write to us prior to placing your order to see if we are able to rush it out and meet your deadline! Thanks for understanding! 🙂 *
**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.**
