The motor mounts in my car are particularly bad. Depending on how exactly you launch from first gear (and second gear if you are running above stock boost) you will get sevear “wheel hop”. I replaced the front, rubber motor mount with a polyureuthene one made by the folks over at AWR. The install was easy and I noticed a difference as soon as I got into the car, the hop was eliminated. The only other way I could tell that it was even installed was the slight vibration in the dash at idle. I could not detect any other vibration at any other RPM levels other than idle. Even the idle vibration was slight.
