Ferrari introduced a number of subtle changes in Singapore to further optimize the F2008 package. One was to the winglets placed on the inner face of the front brake drums, just behind the air inlet. The previous, smaller version, with their slightly upward-curving profile, was replaced with this revised design featuring a completely flat profile and almost twice the cross-sectional area. The new winglets modify the airflow passing close to the inner side of the front wheels in such a way that it can then be better diverted into the radiator inlets by the winglets further back on the car, directly in front of the sidepods.
