Nordschleife Porsche 911(997) 4S PDK onboard
Nordschleife Dunlop Intensive Training/Trackday - 3/09/12 Car; Porsche 911(997) Carrera 4S PDK - Sport Chrono pack (RentRacecar.de) Instructor; Wolfgang Kaufmann Camera; GoPro HD Hero2 with Dogcamsport.co.uk external micro, spot metter mode on(to look clearly the exterior and that's why you see a little bit dark the interior), 960-60 HD quality. First laps for warm-up after some rest, it wasn't too fast as we are as a group, but enough to enjoy the ride, follow-up the instructor jointly with the rest of the group(look at the right mirror), after that he ask me to be the guide driver to show the rest and see my line few cars after me and look the rest also.(2nd lap and others, uploaded). I was the only foreign & non-german on the trackday, as for this needed to change between English-German on the instruction :D The odd sound from the micro it's due the location, attached to the copilot Alcantara seat cover(Recaro race backet) and the friction with it cause this sound, sorry for that.
