I disconnected mine once to see what it felt like on corners. Could hardly tell the difference on curves and corners, even taken at pretty aggressive speeds. Then I turned the wheel hard one way and immediately turned hard the other way, as you sometimes have to do to take evasive action in traffic. It rolled real bad on the second turn of the wheel. I reconneted it. For my truck and my style driving (pretty aggressive and lots of highway miles most of the year) I want it connected. It is fine unconnedted if all is normal, but if I ever have to take evasive action at high speed, I definately want it connected.
