Cusco Type OS (Oval Shaft) Rear Strut Bar For Nissan Skyline R33 GTR 233 541 A

Rear chassis flex steals precision and traction from even the best-built R33 GT-R, especially when lowered or driven hard on track or street. Cusco’s Type OS Rear Strut Bar tackles this head-on by connecting the rear strut towers with a rigid oval aluminum shaft, dramatically increasing chassis stiffness for sharper handling, reduced body movement, and more consistent tire contact under load. The oval cross-section delivers superior strength-to-weight performance compared to round bars, making it a favorite among serious R33 GT-R owners.
CNC-formed from high-grade aluminum with a polished oval profile, this direct bolt-on bar strengthens the rear end without altering factory geometry or requiring modifications. The result is tighter rear-end response, enhanced stability during cornering and high-speed driving, and that solid, planted feel that transforms the driving experience on both road and circuit.
