Overview

This kit sandwiches the rear sub-frame outriggers, eliminating some of the stock bushing's squishiness. These bushings are stiffer than stock but are not the extreme race version, offering a balance for daily driving.
Show original supplier description
These urethane bushings, with a 95A durometer, are designed to sandwich the rear sub-frame outriggers, effectively reducing unwanted movement and improving drivetrain responsiveness. While stiffer than the factory bushings, this 'soft' version is intended to provide a noticeable improvement in drivetrain stability without introducing excessive noise, vibration, and harshness (NVH) for daily driving. However, users should be aware that a slight increase in NVH may be experienced as a trade-off for enhanced performance. This bushing kit is specifically designed to fit the Subaru WRX models from 2002-2007 and the Subaru STI models from 2004-2007. Installation involves replacing the stock differential bushings to achieve a more solid feel and connection.
