Go to your PLR file.
Programfiles -> Rfactor -> Userdata -> your name and then the PLR file and change Mult1 and 2 to zero.
Cockpit Vibration Mult1="1.00000" // Primary vibration multiplier affects eyepoint position (base magnitude is in VEH or cockpit file)
Cockpit Vibration Freq1="31.00000" // Primary rate of vibration affects eyepoint position (higher framerates allow higher rates)
Cockpit Vibration Mult2="1.00000" // Secondary vibration multiplier affects eyepoint orientation (base magnitude is in VEH or cockpit file)
Cockpit Vibration Freq2="37.00000" // Secondary rate of vibration affects eyepoint orientation
