McLaren's low-drag front wing

McLaren and Midland were the only teams at Monza that were running 3 elements on their front wings. All other teams removed a plane to reduce the drag caused by that wing. Apparently though because of the good performance of Raikkonen, the wing seems to have worked well. The third flap was significantly reduced in size as there is a smaller need for downforce at the high speed Monza circuit. The image also shows the end plate of the wing which was stripped of all winglets. McLaren has traditionally kept that element simple, but it is hardly possible to make it even more simple than its incarnation at Monza.
