The XRAY 323357-G graphite rear upright is developed to fine tune the roll centre and reduce rear collapse through faster corners. Designed specifically for the XB2 2024 chassis, it delivers a blend of stiffness and low mass to help maintain traction. Graphite construction gives consistent feedback for setup tuning and race day adjustments.
Fitted with aluminium roll centre mounts, the upright permits several upper roll centre settings. By locating the upper roll centre close to the driveshaft joint axis, the design increases rear grip and stability. That flexibility helps when testing different tyre compounds or track conditions.
XRAY lists four rear upright materials: medium, hard, graphite, and aluminium. Each material alters the amount of compliance and response, enabling racers to match the upright to track grip and personal driving preference.
