Agreed BUT its where you get your downforce from that's an issue. One complaint about more modern designs is that they generate a lot of downforce from the design of the undertray. This rapidly disappears if the ride height changes (hitting a bump would constitute a change in ride height 1). By contrast body mounted wings still generate a lot of downforce in such circumstances. The modern trend in fast exotics is to simplify the body contour and rely on the undertray venturis to provide a substantial part of the downforce at speed. This is often done with fairly flimsy surfaces and can lead to nasty incidents. A Ferrari 360 Challenge Stradale whose undertray has come lose at speed is not the sort of car you would like to be in, in such circumstances. The F40 had a reasonable compromise between wing generated down force and downforce generated from a well constructed but not overly elaborate undertray.
