The Cusco 18 mm rear sway bar is made for CT9A Evo 7–9 applications to reduce body roll and sharpen cornering balance. It increases rear roll stiffness to help control squat and improve mid-corner stability, aiding predictable chassis behavior during aggressive driving. This direct application bar is a common choice when dialing in a firmer, more neutral handling balance for those Evo variants.
