All of the general modification rules of Sport and Tuner Categories are allowed in Max.

Max Category vehicles may only be driven, stopped and steered through the wheels and tires. When the word “unrestricted” is used in these rules, it is under the assumption that the modifications and controls are within this parameter.

Max Category vehicles are likely to be street-driven cars, and SCCA does not encourage or condone the breaking of laws governing pollution control systems or the alteration of street-driven vehicles contrary to state and federal laws regarding their use. It continues to be the responsibility of the individual to comply with such state and federal laws.
