Just FYI for teams - it's best to not be as regimented as the main championship due to the usually high turnover of the secondary championship and the drop-in drop-out style of the event. It should be a case of two people teaming up if they want to but I'd recommend against assigning all 14 drivers from each GT to have to make a specific team.
I think the teams in the 2ndary championship would just be for fun and the mcec atmosphere. At least that's how I'd feel about it when having 3 teammates instead of just driving allone. But I think this would only work if somebody agree's with doing a similar stream where he assigns the drivers by random. And I don't really dare tbh
