If you watch any video today make it this. We all love an onboard video, but we rarely get the pleasure of a rear-facing camera. It’s usually the case that all the action happens out the front windscreen, but not in this case. This rear-mounted camera has managed to capture one of the most exciting battles you’re likely to see accompanied by an incredible soundtrack. The destination is the famous Watkins Glen circuit at the Finger Lakes Invitational, and the battle is between two Porsche 911 RSRs.
