Does handling improve with wheel spacers?

Edumucate me. What does this mean?

Basically, roll center is the point at which the suspension moves about. Think of it like the center of wheel, it's the point where there is no displacement, only rotation. The center of gravity works on the roll center to lean the car through a turn.
