Hey dude sorry to bother you but I have been using your guide for the Porshe Expansion Pack in Forza 4 and have struck a snag. For the achievement pieces of flare you say to use the Nurburgring Nordschleife Full Track but For some reason I don't have it. Instead I have the Nordschleife track which is 20km instead of the 12km track you use in the video. Is there something I need to do first to unlock this track? Any help would be much appreciated.
