For the non Europeans :
- Hockenheim : GP track with perfect surface
- Nordschleife : well, you should now that
- 2,0 bar ~ 29 psi
- 2,2 bar ~ 32 psi
- 2,5 bar ~ 36 psi

(german original) "Statt des für Hockenheim empfohlenen Warmluftdrucks von 2,2 bar rundum wird für die Nordschleife ein Luftdruck von 2,5 bar warm an der Vorderachse und 2,0 bar warm an der Hinterachse empfohlen."

This information is from BMW test drivers for the factory installed Michelin Pilot Super Sport, I think you want get any better source of information.
Thank you.
So just to be clear, I should set the front to 36 psi and rear to 29 warm - correct?
If you are running the Nordschleife

Otherwise it recommends 32 all around for other tracks
