A twist beam (22) for a rear suspension assembly (20) includes an outer beam part (24) and an inner beam part (26) each stamped from a sheet of steel or steel alloy. The beam parts (24, 26) both present an inverted U-shaped cross-section. The inner beam part (26) is disposed between side walls (56, 72) of the outer beam part (24), and the parts (24, 26) present an inverted U-shaped gap (28) therebetween. The inner beam part (26) includes a plurality of ribs (84) to modify the roll stiffness of the twist beam (22). Each part (24, 26) includes an outwardly flared section (62, 76) adjacent an outer side edge (58, 74). The parts (24, 26) are typically joined by spot welds (86) along the flared sections (62, 76).
