Generally on our car, when you add shims under the suspension blocks it raises the roll center. This will give more initial grip, but less through the rest of the corner.

When you take shims out, it lowers the roll center. This makes the car feel very smooth initially, but it will have more grip through the middle and exit of the corner.
