XRAY 303364 Composite Rear Upright - Hard 1-Hole (Race Ready)  [XR-303364]

Precision Handling with XRAY 303364 Composite Rear Upright

The XRAY 303364 Composite Rear Upright offers precise control for drivers tackling high-grip layouts. The built-in 0 deg outboard toe keeps alignment steady under load, while the one-hole configuration favours tighter, more confident cornering on flowing circuits.

Hard Composite for Foam-Tire Performance

Fabricated from hard composite labelled "H", this upright is ideal for foam-tire competition but remains compatible with rubber tyres for club or practice runs. Low unsprung weight and the included 5x10x4 bearings reduce friction and promote consistent suspension movement.

Simple Shim-Based Roll Centre Tuning

Roll centre can be tuned quickly by adding shims between the upright and the turnbuckle ball. This lets you tweak the car's balance to suit varying track grip and driving preference without complex setups.
