BMW M4 vs Porsche 911 997 GT3 Nurburgring

The Porsche GT3 driver was one of the best I had opportunity to race during Green Hell Days from 05-08 May 2016. It’s nice to see GT3 used close to maximum levels. You can see an advantage over M4 few times. Start from about 3:35. M4 is stock beside pads and exhaust.
