Leawood, just GO and test a PDK, and just trying really driving it. You will be surprised about the extra speed you can get above what you can do with a manual. With quicker shifts you can break later, perfect shifts means you can change gear later and carry MORE speed through the turn, and the quicker shifts also means faster exit speed the other side. It was unreal. It does not act and perform like a regular auto or even the tip at all. The current gen PDK software is so good it really can read minds. 

Words cannot describe it, even normal road test won't even show the advantage, it only shows up when pushed, like when you really need the advantage. 

This manual vs pdk on the new GT3 is like the old air-cool vs water-cool debate, and about the case whether Porsche should have done the Cayenne. The choice has already been made for us and the outcome has also been decided, which is new will be better than old. We can either embrace it or stay behind. 

I only embrace the pdk because it is so much better than the manual, had we been talking about the Corvette, I would be 100% behind the manual, their automatic is just too ancient and bad.
