Reflecting the nostalgic look of early stock car racing, these cars are 5/8 scale replicas of 1928 to 1948 American vintage coupes, sedans and pickups. The all-metal bodies are scaled to 73" wheel base and 40" height and are powered by four-cycle motorcycle engines with up to 1250cc displacement.
Please note that the following are "common sense" type rules.
Our objective is to keep this class as competitive and affordable as possible and minimize rule changes.
Do not attempt to build a Dwarf Car without first contacting the Okanagan Dwarf Car Club. If you are contemplating a technical undertaking that is not directly addressed in these rules, please contact an executive member or tech comittee member to make sure it is legal and will be allowed. For more information please contact one of the directors.

OUR MISSION
The Auto Race Car Club Dedicated to Family Fun and Sportsmanship.
Our mission is to conduct safe, honest, and clean automobile racing worthy of public confidence and support. Race nights are truly family affairs, spouses and kids get involved. In the "Dwarf Pit" there are fellow racers from all walks of life, with a variety of skills. Our organization’s strongest asset is that we all work together to put as many cars on the track as possible to make an exciting and safe race. We want fans to have fun as we are, so they will return. Our attitude is if you have a bad tire, "here, use my spare”. After the races we enjoy having the young fans with their Mom’s and Dad’s visit the "Dwarf Pit" and ask all the questions we used to ask. Let us assure you, there are no losers when we race.
We have fun and it shows!
