This will be my 4th winter driving a Crossfire, I do have all season Cont. on it. My first fire an '04 had Mich. tires on it, but with last years 100 inches of snow, I am thinking that it will be parked for the winter very soon, not going to do that again. I was told by my auto tech to drive it in the "S" mode for the winter?! What would be the best mode to have it in?
