More food for thought...
Watch an offroad race vehicle (CORR trucks come to mind) and notice the body roll. Professional drivers mind you, but very controllable trucks regardless of surface. I know, they all run swaybars. The point is that swaybars, or more properly, antiroll bars, are used to tune chassis response. For example, I can tell you from experience you don't want to remove the frt. bar. and leave the rr. connected. This biases the roll resistance to the rr.. Simply put it unloads the inside rr. tire in a corner (enough to lift off the ground if you really crank on it) because while the frt. can roll easily the rr. can't. The result is oversteer or you backing it in to the wall. Just the opposite w/ the frt. connected and rr. gone. The rr. rolls easily, the frt. unloads the inside tire. However irresponsible, when I used to run mine this way, you could carry the left frt. tire off the ground all the way through a left turn from a stoplig,er, tree anytime you were accelerating. Less contact patch at the frt. = understeer. To say that it is unsafe to remove or modify the swaybar, is the same as saying it is unsafe to modify the suspension in any way. All parts; springs, shocks, control arms, tires, air pressure, etc, control the various suspension dynamics that effect the handling of any vehicle. This is why some experience little difference when they remove the bar IF they have stiff springs that are adding roll resistance. Just trying to make the point that everything has to be tuned as a whole.
