The Cusco 18 mm rear sway bar for ZZW30 MR-S applications tightens rear roll control to reduce body lean and improve cornering response. By increasing rear stiffness it helps stabilize the chassis through mid-corner transitions and supports a more neutral handling balance. Suitable when matching a firmer front setup or when seeking crisper turn-in and improved overall handling feel.
