Formula 500

Formula 500 (F500) is a Sports Car Club of America (SCCA) and Midwestern Council of Sports Car Clubs (MCSCC) open wheel road racing class. Formula 500 was originally introduced in the early 1980s as Formula 440 (F440), and is a closely regulated class. Several chassis manufacturers produce different designs to a tight dimensional ruleset. Engines are specified by the ruleset, and builders are not allowed to modify engine internals. Instead of traditional dampers and springs, F500 cars utilize a very simple elastomeric spring medium contained in a cylindrical canister. The rules state the elastomer must be 2" in diameter by 1" in thickness, but the design and implementation of the elastomeric springs (commonly called "pucks" by the competitors) is wide open.Additionally, each chassis manufa
