IAG Race Series Solid Engine Mounts – Subaru Models (inc. 2002-2007 WRX / 2004+ STi)

IAG Race Series Solid Engine Mounts — 2002-2007 WRX / 2004+ STI

Zero-Compliance Engine Mounts for Race Vehicles
The IAG Race Series Solid Engine Mounts for 2002-2007 WRX and 2004+ STI eliminate all engine movement with a solid mount design. No bushing, no compliance — every drivetrain vibration transmits directly to the chassis. This is the specification for dedicated race vehicles where maximum engine rigidity is required and street NVH is not a concern.

DETAILS

• Series: Race — solid mount (zero compliance)
• Cold-rolled cadmium-plated steel brackets
• 6061 billet aluminum anodized carriers
• Completely eliminates engine movement
• NOT appropriate for street-driven vehicles — significant NVH increase
• Requires use of OEM engine mounting plates
• Sold as a pair
• Fits: 2002-2007 WRX / 2004+ STI

Solid Mount Application
Solid engine mounts are purpose-built for competition vehicles. The direct transmission of vibration to the chassis is acceptable in a stripped, caged race car and unacceptable in a street-driven vehicle. For dual-use builds, the 90A Competition spec is the more practical choice.

Maximum Rigidity
The solid mount provides the highest possible engine rigidity — no flex under any driving condition. In a race car, this translates to maximum power transfer precision and no unwanted engine movement during hard driving maneuvers.

Competition Vehicle Application
These mounts are used in IAG’s competition vehicles and by serious racers who need the absolute maximum in drivetrain control. If the build is a dedicated race car, this is the specification.

Why Choose IAG Performance

IAG Performance has been building Subaru-specific engine and drivetrain components since 2001, and in that time they have become the standard by which serious Subaru builds are measured. Based in Westminster, Maryland, IAG designs, machines, and assembles their products in-house using Haas CNC equipment and their own engineering team. Their catalog spans everything from short blocks and long blocks rated to 1150 BHP all the way down to the fuel system, oiling, and drivetrain hardware that keeps modified Subarus running reliably for years. Every IAG product exists because a problem needed a better solution than what was available — and the engineering shows.

The RallySport Take

The IAG Race Series solid engine mounts are for the race car, not the street car. If your 02-07 WRX or STI is a dedicated competition vehicle and NVH is not a concern, this is the mount spec. For everything else, 90A Competition gives you similar performance benefits with a liveable NVH level.
