Nick is correct about the spring pads. The correct thickness of the pads are:
The amount the car will be raised is about double of the pad thickness because of the placement of the spring on the control arm.
It is about half way between the inner pivot point and where the outer hub attach. Another way to raise it is to place a circular piece of material such as conveyor belting on top of the original spring pad. The belting comes in different thicknesses
and is super tough stuff.
