10. Vintage Spirit Rule- From time to time we may allow cars to compete with minor infractions, but will be approved on a car by car basis by UMVRS. It is likely additional weight will be added to these cars. No car deemed dominant and not fitting the rules will be allowed.
Gentlemen’s Rule: The Gentlemen’s rule is intended to spread the fun around. It is a carryover from previous clubs but modified to fit UMVRS. We are asking feature winners to refrain from dominating the series. So, if you win a feature, we ask that you refrain from winning the next heat and feature race that you are in. Additionally, from time to time we get competitors cherry picking our biggest events such as Milwaukee and Oktoberfest. Past year's winners of either of those events can compete, but can finish no better than 4th position. This goes for both the driver and car. Additionally, if we make it to Daytona or Talladega , these tracks fall into the same rule as Milwaukee and Oktoberfest.
A) First Lap: Promoters have talked to us about the first lap. We want all cars to stay in formation until exiting corner 2 of the first lap. Promoters do not like to see 4 lanes of traffic going into turn 1 at the drop of the green flag due to the wide variety of speeds in vintage cars. That means door handle to door handle on the opening lap of all our races at the drop of the green. That means increase speed to near racing levels but no passing until exiting turn 2. Thank you for helping us with this.
