Ohhh yeah sorry I was talking about the ears on the wing not the nose.
And about the horns on the side of the Mclaren's airbox, i also thought it was strange that they produced downforce even though they had no angle of attack, but according to some technical articles they do....
The McLaren "transformer" horns straighten out the airflow and make it less turbulent and screwed up by the time it gets to the rear wing. It helps the rear wing work better.
Concerning the lack of front winglets on the McLarens. From what I understand... the Mclarens are the only cars that use a triple element front wings. And a triple element front wing creates more downforce than the double elements of other teams. But, apparently there is a trade off.
As I've heard it explained, a triple element front wing is vulnerable to wake/turbulence of cars in front of them. More so, I understand, than a double element front wing. So, teams that have only double element front wings seem to be the teams that use the additional front winglets. I did some quick checking and I believe this is correct?
Edit: Just read your question 3. I think the answer would be a combination of Sawtooth-spike's explaination and the fact that any drag created would be washed out by the whole system (the car). What I mean is: it is probably analagous to holding your finger out in a hurricane. Your finger probably won't be the cause of your being blown away. Now, if there were a thousand screws, then that would be a different story.
