One of the components of your car that suffers silently with age is the rubber in the suspension bushings. Over time, they break down and allow more movement of the control arms. This makes your handling sloppy and makes the car feel old.
This Prothane polyurethane bushing set replaces just about every piece of rubber in the suspension. Poly bushings move differently than rubber ones, allowing less deflection and no pre-loading. This means more precise and consistent handling, with a slight increase in sharp impacts.
Includes new bushings for the control arms and differential mounts. It also includes new bushings for stock sway bars and end links.
Installation is not trivial - Mazda Miata Performance Projects runs through the process. Regular maintenance with fresh lubricant is required, which is why we prefer rubber bushings for anything with a license plate.
Bushings fit 1990-2005, although the sway bar bushings are for the 1990-97 end links. The front sway bar bushings fit a 19mm front bar, so please confirm the size of your bar if you are planning to use these.
The differential bushings can cause an increase in vibration in the car. Some people aren't bothered by this, some are.
