Imagine twisting a dumbbell back and forth in your hand versus a ball of equivalent weight. Interestingly, a dumbbell has a 50-50 weight distribution, it just has a high polar moment of inertia.

To my point: The affect of the force of any mass will increase with the square of the distance from the car's center of gravity. So the affect of weight savings as you move toward the ends of the car are much more significant than near the car's mid-point.

Therefore, the weight savings from CCBs will decrease the force required of the tires turning the car.
Your statement is true, however I seriously doubt that 3.6lb per corner can be felt from that perspective. The benefit of CCB on the total polar moment of inertia of the car is there, but negligible IMO.
