dont know if this helps but my settings with my old wheel thrustmaster forcefeedback was.
Digital steering rate 10%
digital throttle rate 10%
digital brake rate 50% maybe you must go lower with this setting???
clutch 20%
Speed sensitivity 50%
under controller 1 settings was
X 50%
RX 50%
Y 70%
RY 70%
Z 70%
RZ 70%
Deadzone all at 1%
forcefeedback settings is up to you what you prefer. I got effects to full and strenght to 15%
now I am just wondering what settings the rest of you racers have.
