STI ride height and suspension stiffness works Fine on snow, assuming you have on some snow tires. Northstar had a good parking lot (in terms of not needing ground clearance) and they plow their parking lots well.
I've gone through upwards 2+ feet of unplowed / untouched snow before in my car . (pretty much up to level with the hood) and didn't have any problems. well besides not seeing shit when you go over 15 mph .
