You don't really need camber bolts to adjust the camber of your wheels. A good alignment shop can slot the holes in the struts where the wheel hub mounts on to allow some adjustment of the camber. When the bolts are tightened, the camber is set.
I had to have that done on my 96 Accent after an accident changed the camber on one side, and never had any problems after that.
It all depends on how extreme you want to go. It looks like the $80 Eibach kit includes new end links and stuff for the lower control arms.
