I had new front control arms and the alignment pins removed at the same time along with the ECS install kit.

I'm not concerned about the harshness because I expected that based on everything I've read. My concern is that the rear of the car feels very loose and if I hit a bump it seems to sway left to right. Is this an install issue or is something causing this?
Get M3 subframe bushings in the rear & M3 differential bushings

In the front, get m3 control arms & new tie rods.
