For those of you who have installed front upper control arms (of any brand), is it normal for the car to feel a little "squirrely" compared to stock control arms?

I also had a replacement Nismo suspension installed at the same time and the car feels pretty crazy at times. Mostly when I'm turning. Straight ahead feels fine.

Trying to ease my paranoia and figured you all could help.
