Whilst rudimentary changes had already been applied to Toro Rosso’s front-wing in Canada, enabling them to pass the new flap deflection test, further changes were made for Spielberg.
In the image above, the lower of the two front-wings is from Canada and features a straight leading edge to the endplate (marked in yellow), whilst the new front-wings endplate features a curvature, changing the way in which the flow moves and builds either side of it.
Owing to the higher downforce configuration required in Austria, the upper flaps (highlighted in green) have also been redesigned, with both of their chord lengths increased, whilst the vortex forming tips have also seen revision too.
