2WD to 4WD -> What setup?

[Rogier]

I've searched a bit and was looking for some specs that I can give the mechanic that is doing the conversion from 2WD to 4WD for me. I didn't find a good answer so I'm posting here in the suspension area. My question is the following:

What are the detailed undercarriage setup specs that a 4x4 should have if I want to have the same driving experience as I had with the 2wd? Terrain capabilities are not important, the 4x4 is for use in snowy conditions.

Any good post-links or opinions are highly appreciated.
