Actually, Spa flaunts both those rules, and the grandfather clause is evident in a certain German circuit that still sees plenty of action despite having a 20.83km lap and a 2.86km "straight".
There are a number of very high end 'club" circuits in the US that flaunt the recommended maximum lap length. Miller motorsports Park has a full lap of 7.242km. Genoa Motorsports Park is to have a full lap length of 9.43km. The combined circuit at New Orleans Motorsports Park will be 8.046km. Coyote Wells Race Resort in Southern California (east of San Diego) is to have a 9.817km Grand Prix Circuit. And as Miller has shown, these tracks are being built to a standard that the ALMS, and even Indy Cars could, in theory, run on them.
Sorry to hi-jack things, but I thought this deserved to be pointed out.
Carry on with the challenge.
