Xray introduce this ultra-lightweight version of the XB4 Gamma 4D body, designed especially for low traction conditions. Lower weight reduces the roll of the car and improves corner speed, while the profile of the body improves the stability and increases downforce towards the rear of the car to help generate more traction for the car. The high-performance, low-profile aerodynamic body for XB4D is designed by Xray to perfectly fit the car and work especially in low traction conditions. Specially designed to maximise rear down force to increase traction the front was designed to give optimal steering. The sides of the body and cockpit are as flat as possible to allow air to flow around the body for improved side stability. On the top of roof are two integrated flow channels for proper airflow. Made from high-quality premium Lexan material.
