Claim: The Williams FW30 front wing could not be altered in order to provide better airflow over the rear of the car.
Evidence: The design of the front wing bridge was tweaked slightly from the 2008 Turkish Grand Prix onward. The bridge element gained two small airflow "fences" that allowed the Williams aerodynamic team to extend the depth of the wing profile. This resulted in an increase in the aerodynamic downforce generated by the wing, without a concomitant increase in drag.
