This is my setup
In the global device settings (control panel) I'm using 110, 100, 110 and centering spring set to game preference
In the game, everything on 100.
In the profiler, game profile f1 2015, brake pedal sensitivity is on 55%, throttle pedal 50,
I like the feel trough the wheel. For the car settings and engineer menus i use game pad mapped with xpadder (arrow keys)
