Ferrari 248 F1 - rear wing endplates 10 March 2006
Part of Ferrari's revised aero package for Bahrain. The endplates previously sported large slits in their upper section. Now they have small ones in their lower section instead, complete with small, upward-curving fins. The function is similar to before - to reduce turbulence generated by the rear wheels, by helping the boundary layer of airflow passing between the wing and the endplate to detach more quickly, hence cutting drag.
