Hi all, my car has been making this noise from the rear whenever going over a bump, since two months ago. I can easily recreate it if I push the car down too. It also does this when I try to lift up the car by hand a little from the rear(weird!)

My fronts never does it. Some days It's completely quiet and is smooth as butter, some days its annoyingly loud like in the video.

Is this a shock related problem? For reference, this comes from both sides, and I do have koni strts installed. (they are buzzing since day 1.) I also have 24mm solid rear sway bar and a eibach pro kit lowering springs (that lowers about 1.2 inch).
