I just saw this thread. It's been 5 years since I've done CMP but I'm signed up for 5/12 in between your rounds of competition.
A friend is in it so I gave him my tips. One note for sure. Turn 11, the kink. Don't lift in the turn. If the back gets light, you spin. Lift or brake before the turn, and then light power thru it. You can see one of my E39 M5 videos here:

CMP June at the bottom is the better one.
