Williams FW29 - rear wing endplates 13 May 2007

Like their rivals, Williams introduced a seriously revised aero package in Spain, including a new endplate design on the rear wing. These now look pretty similar to those on the McLaren in terms of profile and assembly. The curved front-lower edge (two lower arrows) is able to free the airflow passing close to the rear suspension's upper wishbones, hence reducing the turbulence and resulting drag in this area. At the top of the endplate, the three horizontal slits are still present, but are now more closely profiled, again similar to the MP4-22. The changes have helped to improve the FW29's already excellent aero efficiency and balance.
