Meh. Didn't fell like a huge improvement from my previous settings. I'm using a G29. The wheel now feels dead when driving on a straight line, theres no feedback whatsoever from the road bumps, and theres no resistance to turn the wheel when the car is stopped. Also it feels extremely light when driving racecars, which I don't like. It was easier to tell where was the threshold of grip on road cars. But I preferred my old settings so I'll revert back.
Assetto corsa uses the correct degrees for each car, as long as the logitech panel and the ingame degrees are the same. So what you are using is hardware lock, what you'd need would be to activate the "softlock".
But the ac softlock is pretty bad sadly...
For some reason though, the force feedback gets amplified when using less rotation. So going from 900 to 450 will boost (and clip) the force feedback.
I would recommend that yoh just use this LUT like you do now and if the wheel shakes on straights, simply use numpad minus until the ffb is low enough to not shake anymore :)
Or you use 900 and activate the softlock.
Either in content manager or:
\Steam\steamapps\common\assettocorsa\system\cfg\assetto_corsa.ini
Then at the bottom- [SOFT_LOCK] ENABLED=1
