CUSCO 429 311 B14 Sway bar rear for MAZDA Roadster RF (NDERC) ymm_49 Ratio with Standard: 1st Stage:The CUSCO Sway Bar Kit replaces the factory sway bars (if equipped) and uses the factory mounting locations. The CUSCO Sway Bar will dramatically reduce body roll since its stiffness is greater than the factory sway bar or if the vehicle is not equipped with one. The larger diameter and steel strength bar give the CUSCO Sway Bar more resistance against torsion, which helps keep the vehicle stabilized during cornering and reduces weight transfer.
