advantyper,.. yep. I think you found it exactly. Thanx mucho.
The "idea" that because this wing has not been "wind tunnel tested",.. thus making it ineffective, is one of the most laughable comments I have ever heard at CC. Wind tunnel testing does NOTHING to make a wing better or worse. It just adds a small amount of more data to the pool of information as to its relative effectiveness.
Since a sports car's cornering dynamics can not be duplicated in an actual wind tunnel, I would rate actual track testing and handling compassions as much more relevant to a rear wing's overall effectiveness. Anyone with some basic ideas of sports cars, and down force aerodynamics, can easily see that this wing has all of the necessary characteristics to provide some small but significant down force stability to a sports car, especially while the car is cornering at hi speeds. It is in no way a large or radical wing by Porsche standards. And it has the most balanced and best proportioned appearance of any wing that I have ever seen on a Cayman S. The construction quality seemed excellent. And the wing's curves and subtle brake light bar follow the Cayman's design lines perfectly.
Personally I use a slightly larger wing on my CS for track use,.. and all people have different opinions, but I must say, this is the best looking rear wing I have ever seen for a Cayman S and it looks completely OEM.
