Two qualifying sessions will set the grid for a pair of 60-minute qualifying races – the first on Friday, the second on Saturday – which in turn decide how drivers will line up for a 60-minute main race on Saturday afternoon. When the chequered flag falls, the winning drivers and their country will be crowned as champions.
Support events are GT4 International Cup (similar 3-race format) and Peter Auto's Classics race.
I don't see any mention of streaming.
