The I-55 Track Challenge is a 4 race series between the historic Mid-State Raceway in Springfield, Illinois and the brand new Gateway Kartplex in St. Louis, Missouri. The series class structure features a mix of both 4 and 2-cycle classes for all age groups. The series will provide an opportunity for kart races to explore different tracks in their area and will challenge them with bigger fields and new competitors. All four races are schedule on existing club race dates to ensure that racers have the maximum amount of competition at each event.
Because all 4 Track Challenge races are schedule in conjunction with club races by their host track, each class will adopt the weight rules (and LO206 carb slide rules) that the host track requires. This helps ensure great, close racing between the host club racers and Track Challenge competitors.
