Ferrari will use an updated version of its F-duct in Friday practice at the Spanish Grand Prix before deciding whether to keep the concept on its car for the rest of the weekend.
Test driver Giancarlo Fisichella tried out the latest iteration of Ferrari's blown rear wing during an aerodynamic test at Vairano last week, and the team is happy enough to keep pushing on with its development.
As well as bringing on further aerodynamic updates, and the need to move the mirrors from the sidepods onto the side of the cockpit, Ferrari will also give Felipe Massa a new chassis for the Barcelona event.
