Lowering the roll center by lowering the suspension blocks let the car have more roll easier, This will generate more traction overall.

Because of the rigidity effect for the roll, suspension gives more pressure to each tire and it sometimes gives better traction no matter how the suspension works.

They both are just different ways or theory i think?
