November 2022 Rules Clarification for Suspension Covers
#33615 from Michael Devins · Rule change · TB 23-01 (2023-01 Fastrack)
In P1, GCR section 9.1.8.B.D.1, effective 3/1/23, change as follows:
"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 lower surfaces of thepanel. Upper and lower panel surfaces must be symmetrical (mirror images) across a straight line connecting the center of the
leading edge with the center of the trailing edge. Leading and trailing edges may be rounded. Panel angle front to rear and side
to side is unrestricted, but it is not permitted to angle the body panels for the purpose of providing aerodynamic downforce on
the car."
