The gain you get on the straights is enormous, and once you know the corners well you'll be faster with a low wing and splitter setup.
Most of Nordschleife is cornering, its what 13 miles or something and 180 somet corners? Only a small part of it by comparison is long open straights and that equates to higher wing settings. The car will feel more planted thru the corners and the offset against slower speed is minimal at best. You may loose 5mph to 10mph maybe a tad more along the straights but you can possibly gain more with higher wings and a well balanced car in the corners over the entire lap.
Look at these images. One is of the BMW Sauber at Nordschleife...
and the other at Monza a low down force circuit which is predominantly straights...
The Sauber at Monza is running less wing angle both front and more so on the rear than the one at Nordshcliefe! It's exactly the same for a GT car.
Cornering is what is important at Norschleife becuase any one can drive fast in a straight line. The real key is getting the speed thru the corners!
