IAG Street Series Engine Mounts 75A 2002-2007 WRX / 2004-2021 STI / 2004-2008 Forester XT

The IAG Street Series Engine Mounts are engineered for spirited street driving and occasional track use, offering a substantial upgrade over stock Subaru mounts. Designed to reduce engine movement, they provide a more connected feel to the drivetrain and improved throttle response for high-performance street driving.

Featuring 75A durometer bushings—5–7% stiffer than Subaru Group N mounts—these mounts strike the perfect balance between performance and comfort, handling mild power upgrades while minimizing NVH (Noise, Vibration, Harshness). The kit includes eight bushings, cold-rolled gold zinc-plated steel brackets, gold zinc-plated pins, precision-machined 6061 billet aluminum anodized carriers, and all necessary mounting hardware.

A key feature of the Street Series mounts is their interchangeable bushing design. Start with the included 75A bushings and upgrade to 90A Competition or solid metal Race Bushings (sold separately) as performance demands increase—without replacing the entire mount assembly.

Installation is straightforward for those with mechanical experience. With a lift, installation takes about 30 minutes, though it can also be completed without a lift with extra time and patience. These mounts require OEM engine mounting plates. Existing plates can be reused, or replacements can be sourced with Subaru Part Numbers 41031VA000 and 41031VA010 (sold separately).
