To me was more actual (in track use context) total camber i could net. As in, if i could or couldn't get front camber to -3 w/o resorting to install camberplates or not.
BTW, you still have option of powerflex bushings. Imho they might be safer possible issues wise. Those eccentric LCA bushings go in rearward joint, that, if i get it right, mostly moves in just one axis, unlike front LCA bushing, where eg. eccentric whiteline bushings for some fail.
