I turn spring force and damping all the way down and use separated axis for the pedals.. i use the steering lock suitable for whatever car i'm driving. for the Historic GT cars, i use 900 degrees and the recommended realfeel settings included. Most of the time, the cars will come w/ reccommended realfeel settings. The historix mod comes with rfactor ffb setting as well.
here;s an example of a realfeel setting. if you get lots of oscilations, turn the maxforceatsteeringrack up. if you get weak ffb, it is my understanding turning it down will increase ffb? or you can just bump it up somewhere else.
