Nice comparison! Great to see a straight dog fight like that, especially side by side, so that you can see where the advantages were. BTW, most people use the three horn signal for starting a race...
I think something was up with the Z06 though. Was that a press vehicle? I have never heard anyone snatch 2nd repeatedly like Chris was doing. Maybe it was a tired example.
Anyway, it was good to see Porsche get a clear victory, after the GTR episode :-( I still don't believe that the GTR is faster around a proper circuit than the 997 GT3 is, especially if you were to run at least 5-10 laps. Consider this a challenge.
