Max Category is a place for enthusiasts to maximize the street-worthy car of their dreams with minimal limits on engine, suspension and bodywork. Max Category vehicles must have all road-going equipment such as headlights, tail lights, blinkers and windshields/windscreens, if delivered with such. Other than specifically classed kit-cars which do not have headlights and such, Max Category vehicles must be able to be street driven.

Max Category is a restricted ruleset. If modifications are not specifically authorized in these Rules, it is not allowed. (If it doesn't say you can, you can’t.)
