sorry but I disagree. Yes the chassis will roll less with heavier oil for quick changes of direction of short duration, but only because the force lasts for a very short time so the car suspension can't respond quickly enough. For any corner of reasonable length though this is not true as there is still a force when the maximum roll angle is reached.
When the car reaches its maximum angle of roll the force must be entirely compensated for by the springs as the damper is not moving and therefore can't produce a force. The force a spring produces is proportional to the amount it has been compressed, so it must be compressed the same amount regardless of the damper settings. This means that the maximum angle the car reaches is independant of damper settings.
