How DARE you disagree with me!?!?! lol
Understand what you're saying mate, and maybe I should clarify a bit.
We have done aero testing to a degree, lipstick cameras, kevlar tape, that kind of thing.
And yes, much reading of publications such as the one you mention and magnification of race car photographs has gone into what the 34 has. Therefore, what we have now is a pretty good effort considering the technology readily available to us, and the budget. We have one or two other things we've wanted to do but just ran out of time (think long rear diffuser and side skirt modifications) , and the undertray I think is a very good design.
What is harder to do than the easy to see topside stuff is the underbody fine tuning.
If you were here you would have seen how standard the Cyber Evo appeared topside, but from what Tarzan told us, all the fancy stuff is underneath, NOT easily done on a sedan type car. Heck, looking undrneath it gave me nothing, I couldn't see past the F1 ground effect style side skirt carbon sheeting that was blocking the view of the fancy stuff going on!
