 * The Yokohama Independents' Trophy uses a similar system to the Drivers’ Championship, however awards bonus points for fastest laps and race one pole positions (unlike the main series). It also awards three bonus points per position, if an independent driver finishes within the overall top eight, e.g. if a driver was to finish sixth overall, he would receive nine bonus points. Double points are awarded at Macau

All the teams taking part in any of the rounds of the 2009 FIA World Touring Car Championship were eligible to score points for the Yokohama Teams' Trophy. Points were awarded to the two best classified cars of each team, providing they were driven by Independent drivers. All other cars of that same team were considered invisible as far as scoring points was concerned.
