#33318 from Club Racing Board · Rule change · TB 22-11 (2022-11 Fastrack)
In P1, GCR section 9.1.8.B.D.1, add the following:
"No aerodynamic devices (e.g. "skirts," body sides) may extend more than 1cm (0.394 inches) below a lower surface anywhere
on the car to the rear of the front axle. Seat bucket or other protrusions shall not circumvent this rule. Aerodynamic devices shall
be securely mounted on the entirely sprung part of the car and not be movable when the car is in motion. It is not permitted to
duct air through any part of the bodywork for the purpose of providing aerodynamic downforce on the car. This prohibition
includes openings above the front spoiler or splitter that allow air to pass through the front bodywork for the purpose of
providing aerodynamic downforce. Body panels intended to cover suspension components as viewed from the side and above
must not be shaped as an airfoil cross-section or create a pressure differential from the action of air flowing over the upper and
