I'm not really worried about the traction aspect, as I intend to invest in good winter tires and wheels, and I think the car's winter handling will benefit from the 50/50 weight distribution.
However, I'm having second thoughts about driving mine in the winter, because of the low ground clearance, and possible lack of the car having been designed to be corrosion resistant. I don't recall seeing anything about galvanizing or coatings; I noticed some small brackets and under-frame bits on my car already have a splash of surface rust on them here and there.
I decided against additional rustproofing, 'cause it seems a car will start to rust out in an area the coating is inadeqate in anyway.
And damn, those oil coolers look vulnerable to rock spewing trucks and ice chunks!
