If I had not put the Tiens on I wouldn't even consider getting an alignment. The car was aligned by a dealer in Southern Cal 50K miles ago when they replaced the front lower ball joints. It drives straight and tire wear is perfect, the old tires that came with the car were wearing like the alignment was just fine.Only toe is adjustable on the front without buying adjustable suspension pieces. Only toe was out on mine so that was good.
Rear requires (3) sets of adjustable arms to get all the alignments done. There are (3) arms per side that need to be changed in the rear. (2) sets of what you have and (1) set with the ball joint end for camber adjust.
I just got back from the local Goodyear, talked with one of the owners and told him the whole story with the suspension mods, his response "no problem, the lowering springs adds some negative camber and they can get it back to factory specs". When I told him I really like how the car goes through the curves, he mentioned the added negative camber helps with that, but of course the tires won't have even wear. Other than the rear adjustable upper control arms that I'm installing, it is going to Goodyear next week for the alignment.
