If you've noticed, none of the aftermarket spoilers, especially the ones that are being offered by high end "tuners" incorporate the solid/flat section as the oem one does. I don't pretend to be an expert when it comes to aerodynamics, however, I suspect that there's a benefit to a spoiler that's designed to create downforce by allowing air to pass over, under and through it . Take for example the spoiler designs on Carrera GT, 997 GT 2 and 3 vehicles, not to mention most F1 cars . All of them follow a similar design principle .
