I have the greedspeed mount on my tiptronic 1.8T. If improperly adjusted the vibration can be noticeable, and cold weather intensifies the affects. For me, driving is more enjoyable since the engine moves less now, and I am not as worried about breaking a side engine mount(broke one before), or the CAT. Mine also vibrated a lot more when I was running iridium sparkplugs, but smoothed back when I switched back to the stock Bosch plugs.
