The XRAY 303360 Graphite Composite Rear Upright delivers improved traction and more consistent suspension geometry when pushed hard. Produced from a resilient graphite composite, the upright incorporates a 0 degree outboard toe-in to aid cornering speed and to help retain setup after impacts. It is suitable for drivers refining handling balance.
This upright helps prevent unintended suspension changes so the car stays responsive through corners and over curbs. Using shims between the upright and the turnbuckle ball joint enables you to change roll centre quickly, letting you adapt to varying track grip.
With a focus on minimising geometry shifts, this rear upright supports more stable rear traction and improved cornering performance, making it a practical upgrade for competitive and club-level racing.
