Williams FW27 - front wing 19 August 2005
Changes to the front end for Turkey, notably the wing. A double flap (left twin arrow) replaces the previous single one. This provides more downforce, but with only a minimal drag increase, as the flap angle remains low. The endplates are also revised. They are now inclined outwards at the base (bottom-right arrow), similar to McLaren's, and the side fin (top-right arrow) is longer and thinner.
