R Theory NA/NB MX-5 Miata Front Splitter Mounts (1990-2005)

R Theory NA/NB MX-5 Miata Front Splitter Mounts (1990-2005)

This is for only our NA/NB Miata Mx5 Front Splitter Mounts. You can find the entire Front Splitter Kit by clicking here.

For years we have been making the most popular Rear Diffuser kits for Miatas, but we’ve always been missing a front downforce solution. After lots of trials and testing we’re proud to finally offer our NA/NB Miata Front Splitter mounts. The R Theory Front splitter mounts are chassis mounted and uses existing bolt holes in the chassis. So no drilling into the chassis is required making installation easy. The mounts are designed to withstand the large downward forces generated by the splitter, but also designed to flex if you accidentally crash your splitter into curbing or go off the track into the grass. This means a mishap will just bend the mounts instead of bending your chassis. With most mishaps you’ll be able to bend the mounts back into place so you don’t have to buy new mounts.

Purchasing the Splitter Mounts without the splitter blade is ideal for customers who want to make their own custom splitter, or for international customers who want to save on shipping.

The splitter mounts are height adjustable so the splitter will clear whatever front lip you are using. The mounts are CNC cut out of mild steel to ensure proper strength without adding too much weight. The mounts are powder coated matte black so they remain corrosion free and hidden behind your bumper.


1) Two of the mounts bolt to the factory Tow Hook mounts. They will not be compatible with the factory “baby teeth” tow hooks/tie downs, but the splitter mounts will be compatible with most aftermarket tow hooks. If you have any doubts about fitment with your tow hook, please email If you need Tow Hooks, we sell those too: Tow Hook/License Plate Mount

2) The kit does not come with splitter rods, but we can supply APR Performance Stainless Steel splitter rods as an add on.

3) You will NOT be required to drill into the frame of your Miata to install our Splitter mounts, it is a bolt on item.

Splitter rods are an add on extra.
