This is my first E-class and I could not find much info available about people whom have done this upgrade, except this small thread here. That thread is many years old and I did not want to necro that one, so I started a new one. I was very surprised to find so little suspension talk, not just here, but anywhere about the W212. It is a very nice chassis, but the glaring flaw to me is the very soft stock suspension. I get that most owners of this car are a little older and likely more comfort oriented, but the stock shock absorbers/struts are way to soft. They are okay at interstate cruising, but anything with a less than smooth surface and the stock set up is quickly overwhelmed. Even little bumps that my wife's 2010 C350 eats for lunch, upset the car to a shocking degree. When contrasted to my stock, 2023 BMW 330e, it is a downright pillowy mess. Before anyone asks, my shocks are not worn- I only have 35k miles now and they felt exactly the same when I bought the car with 25k miles. Most of my driving is done in urban Los Angeles and I am an aggressive driver.

I am on my 28th vehicle and I have had Bilsteins on numerous cars, they have never let me down. So this past week I ordered Bilstein B6 all around. TLDR: Night and day difference. Big bumps, small bumps, washboard, dips, driveways, you name it, huge improvement. Now it basically rides about 95% as firm as my 330e, about 50% of people might say the 330e ride is too firm. Which brings me to this: If you are the type who values comfort above all else, I would go with the B4's that are quite a bit more forgiving. However, if you are like me and place a priority on ride composure and controlled handling, then you will be happy with the B6's. These shocks have fixed the most glaring flaw on my E350.

Air up your tires; ;those wheels will take a bigger beating with the weight of the car bearing down on every pothole.

The '85 300D was riding on a cloud and had the (lack of) handling to go with it.
The '05 E320CDI was nice n tight.
I found my '13 E350 to be sporty enough.
Moving into my ML350 showed me just how stiff the E suspension is. The ML clearly ain't no sports car.

I am on B6 but at the REAR only.
I started with B4 all around.
I would not want B6 on my front for my road. Thus I tried B6 at the rear first to feel how it is. https://mbworld.org/forums/e-class-w...gine-data.html

My wheel is 18" only, standard size, not 19" or insane 20".
