In Settings > Control Settings > Wheel > Advanced:

Vibration Scale controls the vibration you feel when you lose traction. It's quite light as-is, but if you don't like the vibration, you can turn it off completely.

Force Feedback Scale is actually the Aligning Torque setting, the predominant force you feel in the wheel, not the overall strength of the force feedback. Setting this too high will make the wheel quite jerky, especially on dirt roads.

Center Spring Scale is the force pulling the wheel back to the center.

Wheel Damper Scale adds weight to the wheel.

Force Feedback Understeer controls how light the wheel gets when you enter understeer. It's recommended by the developers to not change this value.

Force Feedback Minimum Force is actually the Pneumatic Trail Align Torque setting. Raising this adds strength to the forces at the center point of the wheel, which is much needed on these wheels.
