Ultra Racing Front Lower Brace - 4 Point • LA4-299

Ultra Racing 4-point front lower chassis brace for Mazda MX-5 MK1 / NA and MK2 / MK2.5 / NB models listed in the compatibility table.

The Ultra Racing LA4-299 is a front lower bar / front member brace designed as an aftermarket chassis reinforcement upgrade for first- and second-generation Mazda MX-5 models.

Mounted beneath the front of the vehicle, this four-point brace links key lower chassis and suspension mounting areas to help reduce unwanted flex through the front structure. Reinforcing these mounting points can help the suspension work more consistently under cornering, braking and changing road loads.

Reassemble and tighten all mounting hardware to the appropriate vehicle or manufacturer specification.
