Its between the Peugeot 308 and the Audi lms, I have been trying to see which one has a better feel, I dont like the other cars very much ,cant get them down
For these cars my "setup" for every track is to set the rear ARB as low as possible, set the brake bias closer to the centre, and... that's it. Perhaps drop some rear wing if there are long straights but often I don't even bother with that. Works for me.
But if you really want someone else's setup, you'll need to say what car you're using. This is one class where we generally end up with a pretty varied grid.
