Formula 600 stands as a premier open wheel road racing class governed by the Sports Car Club of America and the Midwestern Council of Sports Car Clubs. Originally introduced in the early 1980s as Formula 440, the category transitioned through decades as Formula 500 before officially adopting its current name in 2023.
The class is characterized by a closely regulated technical ruleset designed to maintain competitive racing at a relatively low cost. Rather than traditional springs and dampers, many of these open-wheel machines utilize elastomeric suspension mediums contained in cylindrical canisters, putting a heavy premium on driver skill and precise car set-up.
