Salt & Rust.

[Bushido]

try to find a place that does "Rust Check" undercoating.

it's a red oily lubricant undercoat that smells like cherries.

I had my S13 sprayed everywhere, even drilled holes in the door sills to coat the rockers and indie the fenders real good.

It made it through a canadian winter with no rust showing up more than two years afterward. The stuff works.

...and to the guy that said fwd is better than a 240 in the snow, you're nuts. I had a blast driving my s13 with summer tires in snow and ice.
