Agree with Brainofjjj. CMP can be very hard on brakes. When my E92 was new, 1500 miles, with stock everything, I ran out of brakes in two laps. The track is small, thus very little for time for brakes to cool. And spot on re overnight accommodations. No place near the track, so plan of staying in or near Camden, or another location.
You may wish to check on Motorsports Reg site. Somewhere on Youtube I posted a vid of my day at CMP. I will see if I can find a link.
