Vintage Dwarf Car Rules

If it doesn’t 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 DRRWP 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.
