, have developed a thicker, stronger anti-roll bar for the S2 Elise/Exige to reduce body roll during hard cornering. Painted in Cusco blue and adjustable in 2 positions, these bars are a direct bolt-on unit. The OEM anti-roll bar measures 19mm in thickness, whereas the Cusco bar is 22mm, offering increased strength. Cusco anti-roll bars (also known as sway bars) are made using chrome molybdenum (chromoly), which is 33% lighter than an equivalent steel anti-roll bar.
