if i go ahead and do this, what does it do to my alignment?
Your camber will become affected mainly. The toe will also, but not as significantly as the camber. The lower you go, the more you put the wheels in negative camber. Lifting will put the wheels into positive camber. When the control arms are moved up and down, this also changes the angle of the tie rods, although it is very minimal. And when that happens, the distance between the centerlink and steering knuckle changes, affecting the toe. If you don't have a problem with abnormal tire wear now, you will afterwards if you don't get it re-aligned.
