Hello all. Most notably at highway speeds, when the car goes over a bump or imperfection in the road, the car feels "loose". Even more so if it's in a turn. Imagine a car without anti sway bars and it's that kind of feeling. Your head and body moves left and right as the suspension settles. Don't know of another way to describe. it's been at the SC twice and both times they recognize the problem. First time they played with bushings and blamed it on my 21" turbines being powder coated so they sanded the insides. Shockingly, this did nothing. 2nd time, they replaced the rear shocks and performed some "adjustments". It seems maybe a little better but still not there. It literally makes me nauseous on longer drives! Lowering the suspension to lowest setting helps but probably because there is less travel in suspension so it seems firmer. Added bonus, the car now pulls strongly to the right but service records do not show any work performed to front of car. I have an appointment next week to bring it back but any suggestions? TIA
