i know i asked a similar question not to long ago about the possible cause of my car sitting 1/4 - 1/2" lower on the back right side. You cannot notice by eye. My car has stock struts, had tein springs was autocrossed on them a bit and now has GTworx. Just recently started noticing that sometimes when the rear hits a hole you will hear a bottoming out clunk sound not all the time but pretty much 70% of the time unless the bump is smooth and its the right side clunking. Now when I have passengers or a passenger in the car the car feels sluggish and wants to go right when the passengers get out the car feels relieved. But the bumping sound will still occur sometimes. When i push down the car it returns back up does not stick down. Struts not leaking. im confused
