Game on.

Wind tunnel testing measures downforce - which is what you are looking for on your car if you want to take corners faster. If the wing has not been tested in a wind tunnel there is no PROOF that the wing is not going to do crazy things like cause 'upforce' instead... which would decrease your cars ability to take corners at speed.

Downforce with a wing is going to be a consistent variable. It is not going to magically cause more downforce as soon as you start turning your car.

Downforce is going to slow you down on the straight but it will allow you to go faster in the corners. So in effect wind tunnel testing has EVERYTHING to do with measuring how fast you can take a corner... whether you want to laugh at my comment or not.

On the other hand the wing in question could also cause far too much downforce. In which case you are going to be slower not only on the straights but also in the corners.

The design of a wing has to be tested for it to prove that it has balance. Not too much downforce but enough to keep you faster in the twisties - and faster overall on the circuit.

Placebo could have the same effect. The only reliable evidence of effectiveness is with raw measured data.

Yes, we can see that this wing looks like it might be effective - but many factors could make the wing detrimental too. How stable is it on the car.. does it vibrate at high speed? How would you tell by looks alone?

Agreed - I think it looks great.

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.
I agree once again... I think it looks great but unless something has been tested for effectiveness there is nothing you can say to convince me that it is going to be effective.

You're more than welcome to your own opinion though. Just as I am welcome to mine (that proof is needed to show a performance benefit).
