Lower Control Arm Reinforcement Flange :: 99-05

On the 1999 Miata application, Mazda made a change to the end link attachment bracket on the front lower control arms. The 1990-97 Miata was produced with a "U" shaped end link attachment brackets, while the later Miatas were produced with a single-sided "L" shaped end link attachment bracket.

Racing Beat's observations have led them to believe that this "L" shaped design may not be strong enough to handle the demands of a stronger aftermarket sway bar. Racing Beat STRONGLY recommended the addition of these Lower Control Arm Reinforcement Flanges. This modification will convert the "L" shaped bracket into a "U" shaped bracket, and while this modification requires some minor welding. After completion of this modification, the stock end links can no longer be used. Frankly, we have yet to hear of a single example of the OEM setup breaking, but that is Racing Beat's recommendation and having one break could easily result in a very serious loss of control of the vehicle.
