i do not see why a modern high tech approach to aerodynamics can't beat the old school spoiler stuff. and btw, what is really so special about the GT3RS aerodynamics, except porsche rhetorics? the front spoiler is GT3 100%, the wheel arch grills can be found already in my 458 italia and then there is the rear spoiler, no real diffuser of course. they lifted the rear to create a diffuser type effect, but that is makeshift and the main reason why the car looks awkward. all in all, it is a 991 body-kit with add-ons.

on the contrary ferrari works on aereo integrating it into the design and not as add-ons. you don't believe the 488 downforce numbers, fine, but be careful betting on it:::)))
