It's always a good idea to get an alignment after changing suspension parts. Unless you have SPL, in which case ain't nothing moving unless you want it to

Rule of thumb. Anytime you change suspension pieces that effect alignment. You should get an alignment.

Get an alignment from a reputable shop or Nissan dealership service department you trust as soon as possible before you get unwanted wear on your tires.

Yes; when you dial negative camber, will move the toe in the negative direction...positive camber = more positive toe
When performing alignment; always make adjustments at the rear first

Thanks this was the specifics I was looking for. My alignment guy is out for a couple of weeks so I'll hold off on doing the arm with the other parts I'm currently installing.

Well damn, removing and replacing the OE strut/spring assy. with 1,500 mile old 2019 units netted 1/4" greater ride height so gotta check the dang alignment anyway now. I assume 10 years of the front end weight sitting on the springs resulted in 1/4" sag.

I'd wager it was from the rubber spring seats compressing over time.
