Lee Products high-flow solenoid valve
Active front wings were a feature on F1 cars for the 2010 season but have been banned for the 2011 season, to be replaced by the active rear wing. Drivers are able to control the rear wing once they have been behind another driver for a set amount of time, thereby reducing drag on the straight and allowing greater opportunity for overtaking.
A pinion gear at the pivot, with a rack gear mounted on a rod, driven by a solenoid. This would allow the solenoid to be located lower on the wing endplates, lowering CoG.
