Anti-Roll Bar Stiffness - U-Bar For calculating the stiffness of a typical U-style anti-roll bar. For balancing the force acting on the anti-roll bar mounting point is then calculated according to the chosen motion ratio for the anti-roll bar. The anti-roll bar is an important element of the suspension since it allows the designer to control the roll stiffness of the vehicle independently from the bump stiffness.
