Actually I notice it more when driving at lower speed, over speed humps or roundabouts. It feels like the body is moving on top of the suspension and it takes that extra half a second to settle itself.
It seems to settle down at higher speeds. Haven't really push the car yet but hopefully when things opening up I will have more opportunity to do so.
Have you tried adjusting your tire pressure ?
What tires came with your E450 ?
I had the Michelins and haven't faced this issue on 19" wheels.
