I am using these, for in game settings it's essentially default SC Pro profile (not Alex's) with Steering Rack Factor dialed down to 30 from default 55 and Understeer to 25 from 30.
Not sure if it's any different from last posted settings, but here it goes.
For FFB gain adjust "FFB Strength" in game settings, first one from the top on the first image. And of course per car FFB multiplier when driving, recommend to map wheel buttons for that.
