You mentioned better handling. Don't you get more torque to the chassis with the rigid mounting? I would think you would get a rotational effect on the chassis...i.e, more "plant" on the right side at the expense of more "lift" on the left (driver's side). Please explain and educate me!
Thanks,

The old mounts were polyurethane with enough movement to allow my side pipes at exit from body point to touch under hard acceleration, quick shifts, hard left corners at the track under acceleration and such. With this imagine the engine of several hundred lbs swaying or suddenly moving about all of the time. The The momentum of that continues when the engine can't go any further. Reducing engine movement reduces swaying action.
Another way to achieve less movement would be to have a cross member from a strong and solid non-engine location to the engine. The import world does this all of the time with a rigid shock absorber. It keep the engine from making sudden movement and swaying. here's a search for one on a 3rd generation Rx-7. I had one on my Rx-7 years ago. They work very good and transfer very minimal amounts of vibration. If there would have been one of these for my Cobra I would have purchased it.
