The IAG Race Series Solid Engine Mount Bushing Set is made specifically for IAG Subaru EJ Engine Mounts, and is compatible with Subaru EJ series engines for the 2002-2007 WRX, 2004-2021 STI, and 2004-2008 Forester XT. These solid steel bushings leave no room for lurching or movement. This means the available torque at the crank will directly transfer to the drive train, enabling a large amount of power to be transferred to the wheels. The IAG Race Series Solid Engine Mount Bushing Set provides solid stability for high-powered builds.

The IAG Race Series Solid Engine Mount Bushings are constructed from solid steel, providing a solid foundation for your high-powered EJ Subaru engine. Whether you’re looking for performance gains at the track, the dragstrip or for autocross, these solid mounts are engineered to meet the demands of competitive driving. Due to the steel-on-steel design of the bushings, an increase in NVH (Noise, Vibration, Harshness) in the cabin is to be expected, as is typical with solid racing mounts.

If you prefer a softer feel, IAG's 75A durometer street bushings are firmer than stock but more forgiving than our 90A bushings. The 90A bushings are 30% stiffer than the Subaru GROUP N bushings, providing improved support that is ideal for everyday street use and occasional competition events. For high-powered race applications, the IAG Race Series Solid Engine Mount Bushings are designed to provide uncompromising stability and support for the most demanding driving scenarios.
