One compulsory pit stop. No pit window. Tyre change permitted but no refuelling.
Normal standing start.
For this round, we're going to try a rolling start, as per the incidents thread.
Rolling start. Full opening lap, as close to 120 kph as possible, leader calls "Go!" on teamspeak somewhere between the white line across the track near the back of the start boxes, and the start line. No overtaking (no overlapping) before the start line i.e. stay behind the rear bumper of the car in front of you.
Redress. If you're in a first lap accident with a pack behind you, you must clear the track safely and not rejoin until all fast-moving cars have passed and you can do so safely.
Special Spa Rule. Single file through Eau Rouge at all times! The car on the left approaching Eau Rouge has right of way; an overlapping car on the right has to drop back. If you think you are going to end up being two abreast in Eau Rouge, the car on the right has to drop back.
