@mouse: I think that's actually a problem with the latest physics update. Eau Rouge should be easily flat in the FW31.
Just adjusting the high gear might make 6th -> 7th a bit of a sluggish shift. Adjusting the overall ratio (final drive?) to be a bit longer would probably be an OK solution, though. Might make the lower gears a little more sluggish than is ideal, but oh well.
I think having high-downforce at every track is probably a good idea, though. We'll need all the help we can get to stay on track ;)
