Good point Jeff. The thing is, I was looking for a way to reduce the shifter movement without increasing the transmission of the engine vibrations. A 40% increase in motor mount stiffness would no doubt add at least 40% more vibration into the chassis.
That's why I was glad these mounts showed up. Since they sit on the outboard ends of the tranny mount, they can increase stiffness without a noticeable increase in vibration. So far I'd say these things have hit the nail on the head.
