As also noted in the Toyota illustration from Japan, brakes ducts are increasingly serving a role as aero devices. At Suzuka, Williams introduced this solution, featuring a mini-wing (red arrow) with two vertical endplates to increase front downforce.
Brakes ducts are increasingly being used as aero devices, as you can see from this outside fin (red arrow) attached to the inner section of the front duct on the TF109. This was seen at the last round in Singapore and retained for Japan.
In the season's later races almost all the 2009 cars are receiving minor aero updates in areas where the rules leave a loophole open. One such device seen in Japan is this new fin, shaped like two shark's teeth, on the sides of the Force India's cockpit, designed to redirect the airflow towards the...
Visible changes to the Brawn are hard to spot in Japan. This middle fin (red arrow) was part of the aero package introduced in Singapore to increase downforce and improve the quality of the airflow around the central section of the car.
