You are definitely not upsetting any kind of status quo or impuning any vendor.
With regards to the springs I've seen quite a few things reported vary from vehicle to vehicle of the same year since I got mine in 22. Iirc many had negative camber in the front after lowering of course but oddly enough most all of the before and after pics didn't show much. I know pics wont always show. And then for the rears some people had noticeable negative camber and others didn't. All with the same springs. Those who had noticeable camber put on rear arms to correct the issue but didn't have anything like bolts used for the front. And the others didnt use any rear arms. But I think a few sheets I saw varied where some had -1 to -1.5 for the front. But again you could not tell it by looking at it. And reports from a number of them after 5k-10k miles showed no real uneven wear in the front or rear.
So for me it's kind of weird. I'm used to running a little negative camber from doing scca a bit and tracking on a local road course when I had Civic Si swapped out with a 2.0 motor from a prelude that was stroked to 2.2 running coilovers and bars and then a few years later a Focus hatch. Was all too familiar with tires getting eaten if I didn't correct the camber so I'm used to adjusting front and rear camber as needed. But that's where these various reports from others throw me off a bit. So I'm doing rear arms for sure and as I said I may get the bolts to be safe.
