Williams FW30 - front sidepod winglets 23 June 2008

Following the recent Barcelona test, Williams used a heavily revised version of their sidepod winglets in France. They now closely resemble those on the BMW Sauber, thanks to a curved, vertical fin (inset) that connects them to the edge of the car's stepped bottom. This solution has two main benefits. Firstly, it reduces the negative effects of the car's vibration on the winglet, making it less prone to 'flicking' the airflow in non-optimal directions. Secondly, it splits the airflow in two, helping the winglet to better clean up the airflow directed towards the rear of the car.
