Think of it this way, the bars allow your cars suspension to travel up and down freely (as long as both wheels move at the same time in the same direction) they just restrict your cars tendency to lean.
So if your right tire hits a bump, the opposing tire on the same axle will likely move a small amount in the same direction (up in the event of a bump, down for a dip)
I see your point though, however we're just talking about putting an SS/SC swaybar on, they have that bar and are only an inch or so lower. So I doubt that it will affect a drivers habits for the worse.
