IAG Street Series Engine Mounts for 2002-07 Subaru WRX, 04-21 STI, 04-08 FXT

Designed to fit 2002-2007 WRX, 2004-2021 STI, and 2004-2008 FXT Subaru models, the IAG Street Series Engine Mounts are tailored for spirited street driving and occasional track use. These mounts provide a substantial upgrade over Subaru OEM mounts by significantly reducing engine movement and delivering a more connected feel to the drivetrain. With 75A durometer bushings that are 5-7% stiffer than Subaru’s Group N mounts, they enhance throttle response and ensure a more direct power transfer—ideal for high-performance street driving.

A standout feature of IAG’s Engine Mounts is their interchangeable design, letting you adjust the bushing stiffness as your performance needs evolve. The Street Series Mounts start with 75A durometer bushings, but you can replace these with stiffer 90A Competition Bushings or our solid metal Race Bushings. (Sold Separately). Instead of replacing the entire mount assemblies, you can simply purchase one of our bushing kits and change your mounts to street or competition level performance.

Included in the Street Series kit are eight 75A durometer bushings that provide a layer of extra stability over the factory Subaru components. The 75A bushings are ideal for daily drivers or vehicles with mild power upgrades, as they provide sufficient stiffness to handle intense driving sessions, while keeping the NVH (Noise Vibration Harshness) to a minimum. The IAG Street Series Engine Mounts also feature cold rolled gold zinc plated steel brackets, gold zinc plated pins, precision machined aircraft grade 6061 billet aluminum anodized carriers, and mounting hardware kit.

The IAG Street Series Engine Mounts are designed for easy installation. Those with solid mechanical skills can have them installed in about 30 minutes if using a lift; however, you can also complete the installation without a lift with a bit more time and patience. These engine mounts require the use of the OEM engine mounting plates. For the 2002-2007 WRX, 2004-2021 STI and 2004-2008 Forester XT, you can simply reuse your OEM engine mounting plates. If you do not have them, or they are rusted away you will need 1 of each of the following Subaru Part Numbers: 41031VA000, 41031VA010 for installation (Sold Separately).
