okay so after a few races with luke and 1/2 race with ankeet, i have the following findings: You dont need to be on friends list to invite ( theres no option to do so either ) The only car that you can grab from your own garage will be the current one you're using AND favorite You can join lobby while others are playing you can have up to 16 people you can set restirctions on tires/horsepower/which cars you are given a set of recommended stock cars aswell for the track you can only chat in lobby/during free run but it seems like voice comms work during the game. you can also specify the room number. choosing same car to race also probably most balanced if we're talking stock lol So what we'll need for race night in particular is to set a particular time/date and set up cars before hand.
