No way, that is way too low and aggressive for the Nurburgring.
He's all the way down to -20mm all around but yet the springs and dampers are no where near that mark in order to match his ride height.
That pretty much allows no suspension travel and the car will be flying all over the track if you clip the apex. (I used to have a similar setup just to see how aggressive I could go)
Maybe it's just me, but I keep it at a more "conservative" tune which allows the suspension to do it's job.
With that tune for the '07 M3, he said he's at a 7:10, but I'm already at a 7:09 with my current setup.
