Some Popular Slot Car Drag Racing Classes


The National sanctioning body for slot car drag racing, the Scale Drag Racing Association, or SDRA, currently lists almost 50 different Classes of heads-up competition. Included are dragsters, funny cars, sedans, altereds, doorslammers, stockers, trucks, and even drag bikes! In addition, there are 7 Index Classes, which race against a predetermined e.t., rather than heads-up.

While by no means a complete guide to the cars and their Rules, the following chart may simplify how the Classes are broken down by type of car and motor used. See the SDRA Rules for more complete information on these Classes, as well as Race organization and conduct.
