Fits 1990-1993 Miata. These brace tabs, once welded to the rear subframe, will allow the factory subframe to floor brace from 1994 and later Miatas to be installed on the 1990-1993 Miatas. The earlier cars did not have a mounting point for the braces. Welding these pieces to the subframe and the floor provides the mounting points. Legal for Spec Miata. Can also be used on any 1990-1993 Miata for street use or any race class that allows it.
This is the same item offered by Mazda Competition Parts for many many years.
Also order part number NA75-56-3AY from Mazda, which is the Brace itself. Description on the brace kit is incorrect and shows 'L' Floor Reinf. This kit is actually all three tubular bars that make up a "U" shaped brace. In addition, 6 bolts will bee needed. You can source these yourself, or order the Mazda part number 9979-61-225 (QTY 6)

Fitment was very precise. Just what i needed to fit 97 brace to my 93 miata. Steel is thick and very easy to weld. Shown with washers but i did come with my order. Other then that very happy with the parts.
