It is a great "in between" bar.
The rate at the stiffest setting, is stiffer than any other sway bar available....but it is not quite as stiff as a true "Anti Roll Bar" that is designed for straight line use.
My thoughts are, why not just grab the XSB005 that we design for straight line? It is streetable and does not need to be disconnected to be used on the street. It is a little more expensive, but so worth the difference in cost.
