When you're at the limit of the tyres and you press the gas, the wheel turns like 15 degrees by itself, and it's there just by looks, you don't even feel that in FFB, and there isn't an option to disable it. It's just really confusing to drive on two wheels like this, because you require very precise steering, and with this movement you don't know if the car is going to flip or go down. This might be annoying but it can't be that hard to remove this right?

Seems like torque steer and just how wheels work with caster value. An axle will always attempt to straighten itself, hence why stunt drivers give minimal throttle input variation.

I think the issue is that it seems to be only visual and you can't feel it in FFB, as Luan_Racer wrote.
