Do I need to buy a bumpsteer kit or Steeda X2 balljoints if I am lowering my car between 1" and 1-1/2"? I hear the balljoints lower the control arm about 1/2"; if this is true, wouldn't that lower the front-end an additional 1/2"? I have BBK specific rate lowering springs which I will be getting poly. spring isolators, so I think I will be a little more than 1" lower. Opinions on what I should need to do this the right way???
