NSX/ Motor Mounts Hardening Plates

Simple solution to harden your motor mounts, creating more efficient power transfer to the chassis of your NSX. These are also a simple tool for repair of cracked or broken NSX motor mounts.

These plates align the inner spacer with the outer body of the motor mount, assuring the correct orientation of the engine when the hardened mount is installed in your NSX. Once the plates are installed you can use the filler of your choice to 'harden' the mount and maintain the orientation, the plates support the filler to make a stronger bond and allow the largest amount of fill possible because of the conic shape.

Once the mount is set, most customers leave the plates in place but they can be removed if a softer mount is desired. We use 60 durometer castable Urethane in the shop to make the hardened mounts we offer for exchange, you can use any product you choose as long as it is oil and heat resistant. Sold in pairs, enough to do either the front motor mount OR the rear transmission mount(manual or automatic).

We only offer hardening kits for the lower NSX motor mounts because these are the most effective counteracting the forces of the motor without adding undue vibration through the chassis.
