Changed(general mechanic) with Bilstein Comfort struts and bjs and steering shock too.300e still floats when changing lane fast or cornering like a boat.
Mechanic said tie rods and sway bars are okay.He did not want to change control arm bushings as they are okay,he said and changing them may end up causing me 2 new arms if the the bolts are badly rusted.
Asked another mechanic(benz mechanic)and he said the springs are not the culprit unless broken usually and changing them most l ikely will not improve the situation.he said it's the struts.

So is it a characteristic of the Bilstein Comfort struts that make the car drives like a Buick(steering vague and car bouncesfloats)or it's really the springs.The bounce test does not work in such a heavy car.
thanks in advance for any advice.
