IAG Performance Billet Transmission Mount-Subaru WRX 2002-2020

Part Details:

The IAG Performance Street Series transmission mount is designed to reduce drivetrain movement during performance driving while maintaining street-friendly drivability. It replaces the factory mount with a stiffer, more stable assembly to improve drivetrain control under load.

The mount utilizes IAG Comp Series Black polyurethane bushings rated at 75A durometer, offering increased stiffness compared to Subaru Group N mounts. The mount body is CNC machined from solid billet aluminum, providing strength and durability while limiting unwanted flex.

A flush hardware design allows the mount to be installed without disassembly, simplifying installation and ensuring proper fitment. For drivers seeking additional stiffness, the mount can be tuned by upgrading to the optional IAG Competition Series Red 90A bushing kit.

Frequently Asked Questions (FAQ)

What improvement does this transmission mount provide?
The mount reduces drivetrain movement, helping improve shift consistency and overall drivetrain stability during aggressive driving.

How does the stiffness compare to Group N mounts?
The included 75A bushings are slightly stiffer than Subaru Group N mounts, offering improved control while remaining suitable for street use.

Can the mount stiffness be increased?
Yes. The mount can be upgraded with IAG Competition Series Red 90A bushings for increased stiffness and reduced movement.

Will this increase vibration?
Some increase in vibration and drivetrain feedback is normal due to the stiffer polyurethane bushings.

Is installation complicated?
No. The flush hardware design allows installation without disassembling the mount.
