I personally find that having lower wings gives you an insane advantage in Sao Paolo if you can corner your car properly. It's so easy on the straights like this

wings are way too low, to anyone experiencing difficulties i recommend 42-32

Not all of them are perfect, I haven't played the game in ages ^^ Also driving styles are different. Maybe tweak around a bit with the suspension or differential settings

Personally I don't like this setup but Pizza Driver has some good setups that I use. This one personallý wasn't to my liking! A bit to unstable at the rear sometimes.
