Wheel Gamma 1.3 (makes the virtual wheel turrn more progessive on higher angles while still beeing able to make small adjustments around the center), Filter and Speed sensitive Steering 0%. Not really wheel related but what also helps the imersion is to decrease the FOV (i have mine at 45 - 50°, but that is for a 19" screen) and get the Monitor as close as possible behind the wheel. Might take some time to adjust to the new settings but when u are stuck with that wheel its well worth it, and better than a gamepad in any case.
