BMW M3 GTS & M3 DEVOTEC Nürburgring Nodschleife 02.08.2015

Doing my best to follow my friend Dimitri in his war machine on the Nordschleife on the 02.08.2015 Dimitri is the founder and owner of DEVOTEC in France : http://www.devotec-nurb.com Impossible for me to stay in contact with it's 500hp crazy machine, made of real racing parts and on Pirelli Trofeo R tires, but he was kind enough to wait for me two times. I'm running on Yokohama Ad08R, need to upgrade for next season ^^ (exhaust sound, GoPro Hero 4 not perfectly set...)
