My car is great in the snow. I have the benefit of running 16's on dedicated snows in the winter. My suspension isn't all that stiff and the Koni inserts are great on the street.
My alignment is kinda lame this year since my camber bolts are seized, but I've never had an issue running around -2 front and/or rear all year long. Kevin M. was saying the rear probably has enough neg. camber (about -2.2 IIRC) to negatively effect traction, but the front is only at about -1.2 right now.
I've always left my sways at full stiff, but I just softened them up almost as soft as they go accept on the passenger side, it was coming into contact with a lateral link so I went one hole up from full soft and I think it clears now...I should really check to make sure I haven't bent anything yet. I can't even tell that there's a difference but I haven't gotten it sideways or anything.
I had one scare on I80 driving in like 8" of snow last year. I was driving 40mph when I should have been driving 30 and my snows were 3 winters old. The back end came around on me out of the blue and I had to fight hard to keep from losing it. The ass was swinging back and forth like a pendulum and I just kept overcorrecting. After what seemed like an eternity, I finally saved it.
But the car is awesome in the snow as long as I don't have worn snows...and I'm hoping softening the sways will make it even better. I might even remove them completely if I anticipate driving over the pass in a snow storm.
