Just mounted the Super Sports on my Porsche 911 turbo (997 PDK). Driven them about 400km since now. No idea about wear and wet handling yet, but the first impression, coming from the Bridgestone RE050's, is that I have much less tyre-noice than before (for which the 911 has been criticised as a Gran turismo car). The tires feel softer than before, so now it actually makes sense to put the PASM dampers to sport mode when on the Autobahn.
The tyre do seem to have some more tendency to understeer on turn in than the Potenzas, but this should/can be fixed by staying more on the gas during the turn. The SuperSports seem to offer sinilar levels of grip compared to the RE050's, but I have not been able to take the car to the track to test more yet.
But the tires are much more comfortable than the Bridgestones in terms of noise and feel. And in high speeds (been over 300kph on the Autobahn) are still very agile and stable.
So far very happy, as most of the driving I do is Autobahn.
Best regards from Stuttgart
