Overview

These polyurethane bushings offer more precise and consistent handling with less deflection compared to rubber. Upgrading to these bushings will provide a noticeable improvement in your Miata's handling.

Show original supplier description

Worn-out OEM rubber suspension bushings can lead to a sloppy feel in your vehicle. Unlike rubber, polyurethane offers less deflection and no pre-loading, resulting in a significant improvement in your Miata's responsiveness and overall driving feel. Prothane provides the necessary grease for installation and backs this kit with a lifetime guarantee, ensuring confidence in your suspension upgrade. It is important to note the specific fitment for this kit. It is designed for all 1990-2005 Mazda Miata models. However, the sway bar bushings are specifically for the 1990-1997 end links and are not compatible with later 1999-2005 end links. The front sway bar bushings are intended for a 19mm front sway bar and will not fit the 20mm R package bar. The rear sway bar bushings are designed to fit a 12mm rear sway bar.
