Promoter's Option

The Promoter's Option was introduced to TM Master Cup events for the 2013 season. The Promoter's Option allows the promoter of the race to arbitrarily add a maximum of eight cars to the entry list for that particular race. The cars that are eligible for the Promoter's Option include third cars fielded by full-time teams, local teams, or Independent's Trophy teams (though, if an Independent uses a Promoter's Option entry, it will not count as one of their Independent's Trophy runs). This rule was added to allow local drivers into the race, in order to drum up local support, as well as popular part-time drivers, and teams that are not budgeted to run the Independent's Trophy schedule or missed the pre-season entry deadline. The Promoter's Option rule does not apply to Special Events (Karjala, Indy, Decatur).

At the 2013 Round of Ohio, Dale Roswell became the first Promoter's Option driver to start on the pole, and Darren Cardel became the first to win a race.

At the beginning of the 2014 season, only three Promoter's Option entries were available in each race, due to the increased number of teams on the full-time grid. This number was later increased to five after Velocity Motorsports did not appear for the European tour.
