The starting grid for the first race of the season is based on your laptime during the registration. People with faster lap times will be at the front, people with slower laptimes at the back.
For all other races (2 to 8), the starting grid is based on multiple factors: Drivers in D1 will be ordered from least current championship points in front to most current championship points in the back. (Fast drivers start last, to make the race more challenging)
Drivers of all other divisions will be divided into three groups: At the front of the starting grid are those who remained in their division, ordered by least to most current championship points. Behind this group are the drivers who got relegated to this slower division (again from least to most current championship points). And at the back of the starting grid are those who got promoted to this faster division (again from least to most current championship points).
