Sounds noble, but doesn't seem to bear up against a check: A quick search leads to 3 cars' times listed running on UHP tires either: 997 Turbo, 997 GT3 and Audi R8. Out of these 4 cars (incl. M3) only on the M3 and the GT3 UHP tires are OEM spec.

Edit: Found two more Hockenheim times performed on UHP tires: 1:15,4 for the Audi RS4 aswell as the 1:11,8 for the Gallardo. All these times have to be removed then, don't they?
