Doing some TT laps I decided to put the wheel less strength, but when I open Global Device Setting and change the Overall Effects Strengths seems not changing.
I remember that when I was where the pic shows below, the wheel has not locks, u can do the 900°, now I can do 278° like I have it for for the race.
From reading your post, I think you need to go to this page in the profiler to adjust the wheel strength. its the specific Game device settings where you can make adjustments just for F1 2011. Remember to tick the "Allow game to adjust setting" box.
Don't copy these setting though as they are for Race07
