The all-new XB4 human body features high-downforce areas (including front screen and top roof motion channels) for appropriate air flow, and part downforce areas and top main rib for greater stability. The high-performance, low-profile aerodynamic human body was designed by XRAY to perfectly fit the XB4 and use many track conditions. The body is manufactured away from top-quality premium Lexan™ material.
For very-high-traction track conditions, an optional ultra-lightweight human body can be had that'll decrease the roll regarding the automobile and enhance rotation of this car in corners.
