What is the main benefit of using polyurethane bushings over rubber?

Polyurethane bushings are generally more durable and offer more consistent performance than rubber. They are less prone to deflection under load, which can lead to improved handling and steering response, and they resist degradation from oils and extreme temperatures better.

Does this kit include everything needed to replace the outer rear lower control arm bushings?

This kit is specifically for the outer Hyme joint replacement in the knuckle for the rear lower control arm. It contains the necessary SuperPro polyurethane bushings for that specific location. Always refer to the manufacturer's instructions for a complete list of included components and any additional hardware that may be required for installation.

How does this kit affect ride comfort?

While designed to improve handling and performance, SuperPro also focuses on ride comfort and cabin isolation. The engineering-grade polyurethane aims to provide a noticeable improvement in handling without making the ride overly harsh for daily driving.

Product Details

When you're looking to tighten up the rear end of your performance car, worn control arm bushings are often the first place to start. These bushings are critical for connecting your suspension components, and when they're shot, you get sloppy steering, uneven tire wear, and a general lack of responsiveness. This SuperPro Hyme Joint Replacement Bushing Kit is designed to replace those worn-out rubber bushings in the outer rear lower control arm, specifically where it connects to the knuckle.

SuperPro has been developing suspension components for decades, and this kit is made with their proprietary, engineering-grade polyurethane. This material is a solid alternative to rubber, offering better durability and more consistent performance, especially under demanding conditions like those found on a track or with grippier tires. It's built to withstand extreme temperatures, oils, and water, and it's designed to provide a noticeable improvement in your vehicle's handling and performance without sacrificing too much ride comfort. These are designed, engineered, and manufactured in Australia.

This kit fits a wide range of popular performance vehicles, including models like the 2015 Subaru WRX, 2013 Scion FR-S, and 2013 Subaru BRZ. If you're rebuilding your suspension or just looking to restore that tight, connected feel, this SuperPro kit is a well-built option.
