The all-new XB4 human body features high-downforce areas (including front window and top roof movement stations) for appropriate air flow, and side downforce areas and top main rib for higher stability. The high-performance, low-profile aerodynamic body had been designed by XRAY to perfectly fit the XB4 and work with many track conditions. The body is manufactured out of high-quality premium Lexan material.
For very-high-traction track conditions, an optional ultra-lightweight human body can be acquired which will reduce steadily the roll regarding the automobile and enhance rotation of this automobile in corners.
