Ferrari F2007 - front wheel inner fins 13 April 2007
This is an element of the Ferrari you'd only ever notice if you were up close to it when stationary. It is an inclined, partially curved fin (yellow arrow) near the inner front wheel. It helps improve the quality of airflow passing through the front suspension elements, as well as generating a small increase in downforce. Most importantly, however, it raises the efficiency of the bargeboards by reducing the vortices generated by the suspension's pushrod link and upper wishbone close to the front wheel. A small detail perhaps, but one that helps optimise the overall efficiency of the car.
