Ultra-lightweight form of the XB4 Gamma 4D human anatomy is designed specifically for low traction conditions. Reduced weight reduces the roll for the vehicle and improves corner speed. The profile associated with the body improves the stability and increases downforce towards the trunk of automobile to greatly help generate more traction for the vehicle. The high-performance, low-profile aerodynamic human body for XB4D is made by XRAY to completely fit the vehicle and work especially in low traction conditions. Specifically designed to maximize backside down force to boost traction. Front side had been made to provide optimal steering. The edges of body and cockpit are as flat as possible to permit air to flow across the body for improved part stability. On top of roof are a couple of built-in movement channels for appropriate airflow. Created from top-notch premium Lexan material. Fits XB4
