The XRAY 336180 Composite Rear Stiffener is a precision component made for older NT Series cars. Machined from durable composite material, it stiffens the rear section to improve high speed stability and helps keep vintage XRAY models track-ready.
This rear stiffener delivers a good balance of rigidity and low weight, reducing rear-end chassis flex to maintain sharper handling and more consistent responses. It is a sensible upgrade for racers and club drivers who want predictable behaviour through fast corners.
The part is made to slot into XRAY NT Series layouts with minimal fuss and only basic tools required. Tighten all mounting points to the correct torque and inspect the area for wear after heavy sessions to keep performance reliable.
