The Competition Series Engine Mount Bushing Kit is made specifically for IAG Subaru EJ Engine Mounts, and is compatible with Subaru EJ series engines for the 2002-2014 WRX, 2004-2021 STI, 2005-2009 LGT, and 2004-2008 Forester XT. IAG's innovative engine mount design features the ability to swap bushings for street or track use, allowing you to adjust the bushing stiffness as your performance needs evolve. Instead of having to replace the entire mount assemblies, simply purchase one of our bushing kits to fine-tune your engine mount performance to either street-friendly or competition-ready levels.

Included in the Competition Series kit are eight 90A durometer bushings that are slightly stiffer than our 75A Street Series Bushings. These bushings deliver greater stability, while significantly reducing engine movement under heavy acceleration. Designed to enhance throttle response and facilitate a more direct power transfer, they are an excellent choice for high-performance high-powered racing applications. *Does not include pins. Pins are available separately or reuse your original pins.

If you prefer a softer feel, IAG's 75A durometer street bushings provide a middle ground—firmer than stock but more forgiving than our 90A bushings. Also available are the IAG solid steel bushings designed to meet the demands of high-powered race applications. For a softer feel than the 75A street bushings, we have our new 55A Comfort bushings. Due to the stiffness of the bushings, a slight increase in NVH (Noise, Vibration, Harshness) in the cabin is to be expected, as is typical with performance bushings.
