I raced there in my XR2 back in May - great track.

Watch out for the kerbs and some of the ruts next to them, I wouldn't take the entry kerb at Clervaux, and at the chicane just clip the right kerb but take as much of the left hand one as you want.

The dangerous ruts I was warned off are on the exit of the chicane on the inside of the circuit, and also at the Sunny In / Sunny Out corners.
