If you weigh 150 lbs and stand on a 150 lbs coil spring it will collapse 1". If you put a 4"x4" on top of the spring, you stand on the spring again, and the spring will still only collapse 1". The spring rate did not change. Only difference is you are standing 4" higher. . . . . Now, the way a car rolls and leans to one side in a corner is called roll. That happens when the center of gravity of the car acts as a lever arm on the roll center geometry of the cars suspension. The heigher the center of gravity, the longer the lever arm, and thus the more car roll.
