Tighten Up the Drivetrain and Clean Up Every Shift
If your WRX still has the factory transmission mount, there is more movement in the drivetrain than you might realize. Under acceleration, cornering, and hard shifts, that flex translates into a softer, less precise feel. The STI Group N Transmission Mount is designed to fix exactly that.
Built by Subaru with motorsport intent, this upgraded mount reduces drivetrain movement and sharpens overall response. The result is a more direct connection between your inputs and what the car actually does, especially when pushing it harder.
The Group N transmission mount uses a higher durometer rubber compound compared to the standard mount, allowing it to better control movement without sacrificing long term reliability.
This added stiffness helps stabilize the transmission under load, improving power delivery and giving you a more consistent and confident shift feel. Whether you are accelerating hard, cornering aggressively, or running through gears at higher RPM, the difference is noticeable. It installs just like the factory unit, making it an easy upgrade that works with both lightly modified and fully built setups.
