In short, I have been second guessing myself and needed a little reassurance that this indeed is not for everyone, but is hardly a bad thing. Getting more launch to the rear wheels is just a bonus.

The motor and trans are one unit- solidly connected to each other. Solid motor mounts AND a solid trans mount will cause the engine/trans unit to become a stressed member of the chassis- the trans case is not up to the task. By using a urethane trans mount the trans is no longer a stressed member, now the mount will absorb chassis twist- an amount which is significant.
