Vehicles are not judged based on time trials, running order or speed, but rather are given points based on four main criteria:
- Corner entry speed
- Angle (angle of over steer)
- Exit speed
- Adherence to the racing line
Usually a field of 32 cars qualifies for the race day. These 30 cars make 2 solo runs each. The top 16 cars are then chosen from these 32. The TOP 16 is when the tandem drifting competition begins.
The driver with the best technique wins the round and heads to the next round of top 8. This then leads to the top 4 and finally the winner!
