If the sway bar is in contact with the lca bracket, it MAY (not for sure) cause a certain amount of bind in your rear suspension. I would want to get a real data logger and four linear potentiometers on the axle to plot it's motion to confirm that it is not binding.
My bar has a very small gap between it and both the lca brackets and the watts link frame. That said, I can only use the soft and medium settings, otherwise the geometry will cause serious bind on both objects.
