Yes, I would like to know much more about effects with such additions and how people come up with the design. I would vote for purpose over looks but who knows, I own an old LP400s that has the "factory wing", all it does is rip your shirt when you walk to close to the car. Doesn't do anything for performance.
I am in touch with the pit lane and the GT lost full flatshift early on ...so had to go back to manual , also had a puncture....still hanging in there and flying the GT flag...
