When the F duct appeared on the McLaren in Bahrain I mentioned it to our engineer at G4. It's on the list of to do's but the problem is not many MINIs out there have a functioning wing. MINI, even the 2006 GP car, hides its wing too much to do any good.
With a functional downforce device clearly in the windstream, as we are moving toward producing, "dumping" the downforce with an F duct would be possible. The question is, how many people would switch out their MINI wing?
I've watched F1 closely, especially in Barcelona where you could see Fernando operating the F Duct on his Ferrari immediately after exiting a turn. We could do that too!
I think this is a good discussion point, so let's keep the ideas flowing.
