Phazer mods

Just purchased a couple of 2007 Phazers and was wondering what are the best mods or adjustments for them to make them work the best in deeper snow. I am looking for information to help them float over the snow better, run smoother, accelerate better, etc. Not looking for put a turbo on it as the answer, I know that is the best answer, but I don't want to do that right now, just cheap easy stuff. (If there is such a thing.) Thanks for any input.

Thanks for that information. I think that would be the best bang for the buck if I can find them at a good price.
