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.

Anybody have a nav system installed. Did you get the dealer to do it? Did you do it yourself. Which model is the best one? Any suggestions would be greatly appreciated.
