Ultra Racing Rear Upper Brace - 2 Point • RU2-407

Ultra Racing 2-point rear upper chassis brace for Mazda MX-5 MK1 / NA and MK2 / MK2.5 / NB models listed in the compatibility table.

The Ultra Racing RU2-407 is a rear upper bar / rear upper brace designed as an aftermarket chassis reinforcement upgrade for first- and second-generation Mazda MX-5 models.

Mounted across the rear upper body structure, this two-point brace links the left and right rear upper mounting areas to help reduce unwanted flex through the chassis.
