Ferrari F10 - revised front wing

For the first time this season, Ferrari have introduced a double-flap solution on their front wing at Silverstone to increase downforce. The previous, single-flap solution can be seen in the top drawing and the new version in the bottom drawing. Of particular interest is the more sophisticated shape of the profiles, which rise up in the middle section of the wing (see red arrows in bottom drawing).

Performing Tyre changes in 3 seconds

As the cars completed all the testing that is allowed, the crew on track and at the factory have been practicing pitstops without refuelling the car. While previously the tyre changers were not the critical path of a pitstop procedure due to the longer refuelling time, they certainly will be now.
Williams have stated a 3.5s stop will be "decent", but rumours from Red Bull claims pitstops of under 3 seconds. To optimise this process, most of the experienced teams have designed special wheel nuts that can unlock the wheel safety fastener and the wheel at one time. Ferrari did it by adding two clips on each side of the nut.
