Racing Beat/Supermiata Sway Bar kit MX5 Miata 89-05

Racing Beat sway bar

90-05 Mazda MX5 Miata

Sway bar kit includes center pivot bushings and brackets for those bushings.

Racing Beat offers an optional "Brace Hardware" kit that consists of two aluminum blocks to reinforce the sway bar bushing brackets on your chassis. We recommend these bracket reinforcing blocks if the car will be used on track.

Which bars?    Note: these bar recommendations assume a ride height around 5" at the pinch welds or lower.
