Abstract
A trailing rear suspension for a motor vehicle having a twist beam axle coupled at its ends to a pair of trailing arms wherein the twist beam axle raises the shear center of the central portion of its cross-beam above the wheel center of the vehicle. The raising of the shear center is achieved by rotating the cross-beam to orient one leg of its cross-section to be aligned with the top of the trailing arms.
