I don't own a GEN but i have heard of people wrapping foil around the head to keep the heat in when the weather is cold... i can see it working great but its best to check the temps after a while in case things get to hot!... or you could just put it around until the engine gets warm?

i have also heard that suspension arms become brittle in cold weather so if your planing on hitting allot of things will great mass then your car () you can boil the arms (the cars not yours *lol*) in water the night before, which "ment" stops them braking

Have fun [8D]
