I think we have now reached the end of highering the front wing, as we are at a point where the nose must be made higher and higher to keep above the wing anyway.
However, suppose we don't do that... what would we have then? I think that at the moment (eg Toyota TF105) space between front wing and nose are so small that it is unlikely to be very good for the aerodynamics.
Thinking about it, I came to the idea of reverting back to the beginning of the nineties. Lets get in mind the Williams of 92, low nose cutting the front wing in the middle. Does anyone think it would be worth finding out if such a configuration could be realised with a high nose. I mean sure you would need a rather low high nose, but if you would higher the FW at the MP4-19 you'd have what I am talking about.
Just my mind taking me away... what do you think?
