I think Turn 10 have done a great job in all releases delivered. But there are two things that I would like you take a look.
The kerbs of Nordschleife circuit are not real. Whe the car passes in the kerbs, specially becouse Nordschleife’s kerbs are hight, the behavior is not real.
Other point is the modeled track itself has som differences from the real. See this video: https://www.youtube.com/watch?v=39cMDUvGA4c
