you move it left and right by, raising the outer or lowering the inner upper a arm mt.

steve smiths computer program is the only way to go.. its sooooo easy its scary..

the program tells you everything bump steer, roll center, caster camber curves etc. all by just measuring all your stuff at ride ht and putting it in, then you can make the changes on the computer and see exactly what you need to do.

basically one inch up or down on either side moves the roll center on my car about 8 inches to one side or the other.

my exact program is front suspension geometry pro.
