yeah dude....drop that puppy down to like 25 on snow covered roads. it's my winter pressure as soon as snow hits.
as far as sway bar...i've not been sway bar'd since the superlift almost 3 years ago, so that's a non-issue as far as snow driving. I've not experienced anything adverse effects.
EDIT: something to also consider....condition of that front shaft after the superlift install. mine only lasted 4k, while others last 30k, and yet some last 10miles. If it's clicked into 4 or even just in 2, it'll take a poop. so that might be a cause to your issues too.
