I was wondering how many of you guys have either the engine mount inserts or rear/side motor mounts in the colder environments, aka during the winter time. I live in Vermont, and if you didn't know, it gets pretty cold up here. The MS3 is my DD, so I was wondering how harsh these upgrades make the car feel when the temps dip below 20 degrees. My buddy has an MP3 with really stiff mounts, and his felt like it was going to rattle apart when it got cold outside. Should I wait until the spring to upgrade?
