For those who haven't been lucky enough yet to drive there, it's the hardest track I can possibly think of to be doing this. Narrow, bumpy, big changes in grip and camber and lots of things to hit.
Even if I was much better at this than I currently am, I still wouldn't be doing it there in an E9x. Total respect for our forum fellow!
