can't speak for others
I cant/won't speak for others but every SG rear car I've owned and/or had the pleasure to drive (many) were great in snow or less than tractionable surfaces BC of the SG diff, it really does makes a difference - but none were four spd cars so I would suppose that would add less than desirable element to the mix... still I'd rather have the SG than not in snow or "slickery" situations. As for the Show offs and 1/4 milers...... some of us are just gonna have some fun letting it all hang out every now and again.
