Glad I found this thread so I know I am not the only one. I have the S 75d, 19 tires, coil, 4k miles, and took delivery the last week in December. Totally different suspension coming from a Lexus. This last week I took it to the SC and they said the very tight suspension is a characteristic of the car. They pull the wheels and checked everything out. I have noticed as the weather has gotten nicer it is not as rough. The things that hit home for me on this thread was there a bad batch of suspension parts during the December/January timeframe and the occasional harmonic effect. I am in the process of adjusting the frunk/truck and lowering the tire pressure a little to see what improvement that provides.
