In view of the disqualification by the FIA of both the cars of theBMW WilliamsF1 Team in the Canadian Grand Prix  here is a statement from Sam Michael, Technical Director:

"The front brake ducts of Ralf and Juan Pablo's car are not in accordance with the regulations. It was a mistake and it was unintentional.

There was no performance gain and no gain for brake cooling because the inlet area was not bigger. However the duct is not in compliance with the technical regulations, therefore we accept the FIA decision."
