What makes polyurethane bushings better than rubber?

Polyurethane is a denser material that offers more resistance to deflection than rubber. This means less unwanted movement in your suspension for improved handling. It also tends to be more resistant to degradation from oils and extreme temperatures.

Will these bushings make my ride uncomfortable?

SuperPro designs their polyurethane bushings to retain OEM levels of noise and harshness isolation. While they improve performance, they aim to keep ride comfort a priority, so you shouldn't experience a harsher ride.

What is included in this kit?

This kit includes the necessary SuperPro polyurethane bushings for the rear upper inner control arm application on your Mazda RX-8.

Product Details

Control arm bushings are key to how your Mazda RX-8 handles. They connect suspension parts and allow for smooth movement. When these wear out, you might notice slower steering response, a general sloppiness in the drive, and uneven tire wear. SuperPro's engineering-grade polyurethane bushings are made to replace those worn-out rubber ones, offering a more durable and responsive pivot point for your rear suspension.

Developed over decades of testing in tough Australian conditions, these bushings are built to last. The proprietary polyurethane formula resists damage from extreme temperatures, oils, and common automotive fluids, meaning they hold up better than stock rubber. While they improve your RX-8's handling and performance, SuperPro also focuses on maintaining a comfortable ride, keeping noise and harshness isolation close to OEM levels.

This kit is designed to be a direct replacement for your factory bushings, helping to restore precise steering feel and reduce unwanted suspension movement.
