The F2oo7 has been running a few new developments, but I can´t verify them with complete certainty for the time being.
For now, what do you guys think about the new winglets around the brake ducts But from the few pictures I have found of them, the angles aren´t very telling, I can´t come to a conclusion whether they are on the brake ducts, or surrounding them. Such as this pic below.
From what the photo comparison demonstrates, they went from the brake system enclosure to the brake duct.
End note: There is a huge difference in brake duct size from each car, although this might depend on the circuit from which the photo was taken at. Or whether they were running wheel covers on the 248F1 to aid in brake cooling or not.
