The following items were discussed and consensus was obtain by the Stakeholders in attendance.
To run for a points championship in any series, a substitute driver can only be utilize once in each series. Any driver using a substitute driver more than once in any series will not be able to run for a championship in that series. The NXS15 and GEN6 series no substitutions are allowed during the chase. You can still miss 2 races during the season in these 2 series and still qualify for the chase. So you can use a substitute driver for one race and miss one race and still be qualified for the Chases.
Any race with less than 8 drivers will have the race shortened to 25%
Any race with less than 4 drivers the race will be a rain out.
