I use second gear to start in wintry conditions, gives less tire spin when you take off. I can tell you from experience the Crossfire is better in ice and snow than a 300z or a Corvette but all three are not winter weather cars. My only other suggestion is keep your speed way down if you have to drive in bad weather. I'm lucky, I usually keep mine in the garage until they clear the roads. I can walk most places, including work if I have to.
