This is a CNC laser cut under tray for the NC Miata (’06-’15) made by LRB Speed. The tray is made of 0.080″ aluminum sheet metal with an even brushed finish and will stand up to all the road can throw at it!

This tray replaces the stock plastic NC undertray that is typically missing or damaged on most cars. Not only does it look great, it also adds rigidity and support to the front bumper.

This setup uses all existing mounting points on the car (no modification to your car is required*). There is also a drain hole to drain the radiator without removing the undertray or uprights.

All hardware as well as installation instructions included!

You are able to purchase the whole kit, or either the undertray or uprights by themselves! If you have any questions feel free to contact us! 


  • Our 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!
  • If you purchase the undertray only you will need to drill 2 holes in the plastic uprights, but there are still no modifications to the vehicle itself. 
  • 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.

PLEASE NOTE: Every product is custom made to order, not a product sitting on a shelf. As such, each order takes some processing time (usually 3 weeks) to produce, package and ship. If there are any questions we have on your design (most of the time there isn’t, but we do get some combinations that are tough to see), we will send an email to you about your order.
