Guys, just in case you are interested: I asked Porsche for the drag coefficient of the Gt3 and Gts They kindly replied and I found the answer somehow surprising:

Luftwiderstand "Cw-Wert" der angefragten Derivate:
GT3: 0,34 
GT3 Touring: 0,35 
GTS Modelle: 0,32-0,31

I wonder why the Touring, who shape wise is mostly the same as the Gts would have the highest value? Even higher than the Gt3 with fixed spoiler?

I imagine that these measurements are taken without extended spoilers. If they were taken with the spoilers raised then maybe it could be that the Touring one stands steeper in the wind. But what do I know… II have not read any comments in the presentation or interviews with AP in this regard. 

Any thoughts on this?
