Western States Dwarf Car Association
2016 GENERAL RULEBOOK
With the nostalgic look of early stock cars, Dwarf Cars are 5/8 scaled copies of 1928 to 1948 vintage American coupes, sedans and trucks. They are powered by a motorcycle engine. The bodies are scaled down versions of full size cars.
If it doesnt say it in this rule book, you can't do it!
The following are "COMMON SENSE" type rules. Our objective is to minimize rule changes. Do not attempt to build a Dwarf Car without first contacting WSDCA for rule clarification. No exotic equipment, (meaning unusual or out of the ordinary). If a car is built that does not meet the Dwarf Car specifications, it will not be a Dwarf Car. Interpretations of or amendment to these rules may be made at anytime. The rules and/or regulations set forth herein are designed to provide for the orderly conduct of racing events and to establish minimum acceptable requirements for such events. These rules shall govern the conditions of all events, and by participating in these events, all licensees will be deemed to have complied with these rules. No express or implied warranty of safety shall result from publication of, or compliance with, these rules and/or regulations. They are intended as a guide for the conduct of the sport and are in no way a guarantee against injury or death to participants.

The WSDCA board of directors shall use the following guidelines for the imposition of penalties in the situations describes below, but may assess a greater or lesser penalty depending on the circumstances.

These are common sense type rule violations. They are designed to give Clubs an outline on how to deal with violations and categories those violations may fall under. We should keep in mind that it’s our goal as officials to promote and encourage the growth of our sport and to increase car count and not to use these violations as a method of singling out or disqualifying drivers from an event. All cars should be
teched prior to any event and all tech should be carried out by assigned personnel and should be between the driver/owner of the car in question and the tech person. Any tech issues not resolved should be brought up to the board of directors for clarification.
