XRAY 303351 Composite Right Rear Upright - Track Tuned Rear Component  [XR-303351]

Lock in tighter lines with the XRAY 303351 upright

The XRAY 303351 Composite Right Rear Upright is engineered to refine rear-end behaviour for cleaner lines through corners. Providing 1 degree of outboard toe-in, it helps the chassis resist roll and keeps suspension geometry intact during hard laps or knocks. The medium stiffness suits rubber-tyre configurations while remaining functional with foam tyres as well.

Performance and adjustment features

This upright includes two roll centre options so you can fine tune balance and weight transfer for different tracks. Fitting 5x10 ball bearings keeps rotating mass low and improves turn-in precision. The design gives reliable performance across both rubber and foam tyre setups.

Installation and pairing advice

Use this part in combination with the left rear upright 303361 to ensure a balanced rear end. Match it with the suggested rear components and tune toe and roll centre to suit your tyre choice and driving approach, whether you run rubber or foam tyres.
