I am getting feeling that I am on a right track chasing down that bump steer bouncy wheel.
Seems like it’s mostly from Steering Rack effect, which is defaulted to 55% for some reason while R3E site recommends to keep it at 30% if not lower.
The steering rack setting is a bit of a mysterious one, it is very dependent on the car you drive, what kind of effect it has. On the newer physics, it will have the intended effect of making the FFB feel more as if it is really coming through the steering geometry, rather than directly from the tires, often making the steering go a bit lighter when turning more. However, it has some very odd effects with FWD and AWD cars on high % settings. This is why we decided to keep it at 30%, to get most of the benefits, but without the negatives. I would not recommend going over 50% with this to avoid those side-effects.
30% seems to make wheel heavier in turns you may want to adjust Steering Force Intensity and makes that bounce less pronounced as wheel stays more “loaded” in that condition versus losing resistance and abruptly gaining it back. You can go even lower, there are some trade offs, increased resistance and what seems like more scrub from tires.
