Jeff,

I think the other thing to keep in mind is that the money cars/clubs are the cars that are hurt the most by CMP design. The bigger and faster the cars, the harder they are on brakes and the more they need time off the brakes to cool them down.
CMP just doesn't allow for that. The attendance for some car clubs that cater to bigger/faster cars like Corvettes, Ferraris, Porsches, Mustangs has been dropping off because of that.

A look at the high rock course design shows they will not have those kinds of problems.

Barber Motorsports Park is also making very similar changes to its configuration right now for the same reasons and that they are trying to keep Grand Am happy and attract the IRL.
