If you manually disconnect the sway bar, or put in a disconnect, it allows the wheels to articulate better, and independently. You WILL get more body lean in corners, but I haven't found this to be too much of a problem. I haven't had a sway-bar now for about 2 years, and I don't miss it.
I gave my sway-bar, with the cool Rotational-Dynamics Prototype disconnect welded into it, to Heather, for somebody in Idaho, I think.
