Energy Suspension Complete Poly Bush Kit for Mazda MX-5 NA NB


Energy Suspension Complete Poly Bush Kit for Mazda MX-5 NA NB

Rubber softens over time, reducing its ability to hold your suspension components firmly in place. This means that when your wheels hits the road, the once meticulously aligned suspension is able to flex, moving your geometry along with it. By replacing your tired rubber bushes with uprated polyurethane, your suspension keeps its alignment better, making your car handle more positively and predictably.

Moreover, the design of these bushings is more akin to a bearing, allowing the arm to move freely up and down while being solidly located within the arm. This allows the suspension to do its job rather than the control arm bush acting as a damper in motion. Highly recommended by BOFI Racing to ensure predictable, repeatable handling characteristics, giving you an even better feel in the hand than when the car was new.

Fitting Notes; Anti Roll Bar bushes are suitable for an NA and may be too small / large for NB.
