The XRAY 303360 Graphite Composite Rear Upright is purpose made to boost traction and rear stability for on-track performance. Made from a precise graphite composite, the upright features a built-in 0 degree outboard toe-in to help maintain suspension geometry and improve cornering under load. It is aimed at racers who want dependable handling upgrades.
Its shape reduces unintended suspension movement so the car reacts more predictably in corners. You can fine tune roll centre using shims placed between the upright and the turnbuckle ball joint, making setup changes fast and repeatable for different surfaces.
Engineered for competition use, this rear upright helps limit chassis geometry shifts to keep the rear stable and increase cornering speed, a practical choice for racers and serious weekend tuners.
