Efficient rear wing works in conjunction with the X1 racing body. The rear of the body has flow channels which direct air directly onto the wing to generate rear traction and stabilize the car.

The wing is assembled via the rear wing mount system which features a graphite mount and aluminum stands. Using optional alu shims between the wing and the alu stands, the position of the wing can be easily adjusted for various track conditions. The height of the rear wing can be adjusted by changing the mounting position on the graphite plate.
