Looks like driver error to me, he runs the car without the rear spoiler and has less downforce on the rear wheels and is properly going on the dirtiest part of the road and turns the car in way to quickly, the car looses traction at the rear wheels due to a combination of dirty road and to little downforce. If he had driven the car in a straighter line and slowly sliding the car right just by a few degrees he would probably not loose it as he did....IMHO..
Not saying mistake were not made but turning in too quickly was not the cause, I have better video than the stuff you can find on the net and have slowed it down several times.. Thanks for your help though!
The first picture is a nano second before the back end does the wild thing..
