Dan,

People with performance cars have used urethane for years. It just wasn't a viable option because of the OEM application for our mounts.

Urethane can be purchased in 3 hardnesses for this type of job. The 80 that I used is typical of a urethane mount you would buy from the various companies for high performance street use. You can get about 96 shore for racing applications. And you can buy a urethane that is roughly the same as the OEM rubber.

No doubt these will transmit more vibration into the cockpit. I would expect much less engine movement.

I will purchase a urethane trans mount from Summit or others to go with the engine mounts.
