New motor mounts?

Anyone buy and install those new stiffer motor mounts in their car yet? Any feedback or thoughts? I worry that the lack of movement in the strut will transfer vibration from the engine into the cabin, or put stress on the axels that might cause premature wear. Motor mounts are suppose to flex. I understand the theory. Porsche is working on a fluid motor mount that is regulated by throttle and power demand to do the same thing. I wish it weren't so expensive either. $130 is a bit much.

The stock motor mount is designed to support the engine and transfer as little vibration as possible to the passenger cabin. Because of this, when you step on the gas pedal... what happens? The first thing you feel, before the car really even starts to move, is you feel the rear end of the car sink. That's because when the torque is applied to the wheels, the front motor mount allows the motor to move quite a bit. So instead of all (or a lot of) the torque going to the wheels... a fair deal of it is wasted on the motor's ability to move around. If you limit the motor's ability to move, you decrease the power lost due to it moving. As it's been said several times in the thread jwight linked to.... it's been known about by people who build hot rods and such for years.

A simple motor mounts ain't any good. It's just a trick to lighten your wallet.
