But it has almost no run off, room for error, or guard rails on even the steep drop offs. I have been there 9 times, around 50 total runs.

I was chasing M3s and M6s, and they were chasing me. My in car video is good but a friends video, chasing me in his e92 M3 is even better at showing how flat the X5 corners and how well it exits them. He needed to wind out the short straights, and brake deeply to catch me into the next turn many times.

Regarding under steer, just learn to be a bit slower in and power thru the corners. Even full DSC on, I could rotate the X5 a bit with the throttle from mid corner thru corner exit.
