INDIANAPOLIS – The USAC Silver Crown Champ Car Series has announced two rules updates in regards to car construction and body regulations.
Section 203.E of the Silver Crown rule book, which states that “all cars must have an aluminum guard behind the driver extending from the front of the step in the tail tank to the floor pan, and this guard must extend the full inner width of the frame,” has been removed.
Meanwhile, section 203.K of the rule book has been revised and now states that “side panels covering the sides of the engine may not extend vertically any higher than a horizontal plane with the dash. Side panels cannot extend above any part of downtubes and must be the same height on right side and left side.”
These changes have been issued with immediate effect for the 2020 season.
