Hardened mounts have long been a valuable asset to any engine rebuild or form of chassis tuning.

Aimed primarily for track and circuit users our modified mount is based around the already improved STI version but with the addition of further material. This makes the RCM mount the firmest available without utilizing a solid mount and so helps limit transmission vibration from traveling into the body shell whilst still dramatically reducing gearbox movement, (particularly under acceleration, braking and hard cornering).

When combined with STI's Hardened engine mounts, flex and twist in the engine will also be less, improving the overall driving experience and helping engine power transfer into the drive train more efficiently.

This mount is a direct replacement part meaning no modification is required.

• Utilizes the hardened Group-N STI transmission mount.

• Additional Polyurethane pockets are molded into the mount to further improve stiffness.


• Improved Stiffness over the STI Hardened transmission mount.

• Maximum reduction in gearbox movement under acceleration, heavy cornering and braking.

• Improved driving response.

• Helps to channel power from the engine into the drive train more efficiently.

• Although the hardest mount available vibrations into the body shell are still reduced thanks to its rubber compound.

• Excellent compromise over maximum stiffness and comfort.

Fits the following models fitted with a five speed transmission: 


• All Subaru Impreza's from 1992-2011 (including non turbo, limited editions and JDM models).

• All Subaru Forester's from 1996-2012 (including non turbo, limited editions and JDM models).

• All Subaru Legacy's from 1992-2009 (including non turbo, limited editions and JDM models).
