Ferrari 248 F1 - barge board revisions 22 April 2006
Part of the revised aero package for Imola. Though the boards themselves look little different, the changes are in the cross sections of the winglets attached to them. The lower winglet has been slightly enlarged to better manage airflow passing under the car. The upper one is also slightly bigger, helping to split the airflow passing close to the sidepods. This cuts the vortices around the sidepod entrance, allowing more air to enter, hence improving the car's cooling capabilities.
