A few months ago I installed a set of YSR coilovers on my 2004 E55 and at first i loved it, car felt planted and nice, but then quickly came to the realization that the car drives like absolute kaka. Now this could be due to the rear subframe bushings needing to be replaced who knows. I am just not at the age anymore for a rough ride especially after 5 motorcycle accidents and a few broken bones.
I may be selling the coilovers, I will update here if I do but will be replacing the rear subframe bushings first and seeing how it drives then and go from there.
They for sure ride firmer than stock. You also have to find that perfect balance of spring rate control with the damper settings. To much and it will ride horrible with little give over bumps.

I like the firmness, I just don't like the bouncy rear slapping all over the place. I cant seem to find the right balance either I've spent HOURS trying to find the right spot. I have the air suspension parts ready, I could always return them but I guess I will see once I have the time to change the rear subframe bushings

If your rear subframe is truly sloppy, fixing that will make a big difference. Im sure you are also aware that these rear subframe mounting points can break at the frame and you might not see it until disassembly. Not saying this will fix shock performance, but it will remove a large variable for you to get the shocks reacting properly since the shocks are moving in directions they are not meant to.
What brand coil overs? I scored a set of BC coil overs from the junkyard but have been hesitant because there's things I like about the air suspension that I don't want to lose.

they’re YSR coilovers direct bolt on no need to replace rear lower control arm. They just pop right in
What bottoms out?
The tire bottoms on the wheel well?
The body completely hit the rest of the suspension ??....which would be insane if it was !
I am honestly not sure but with my previous experience with suspension, I believe it is the tires bottoming out on the wheel wells but the rear shocks absorbers may be too soft .................. could also be the random crap i have in the trunk
So, what are the spring rates on the rear suspension? How do those spring rates compare to others? Did the seller provide that information to you?
Suspension engineering is complicated. Learned this years ago on NA Miatas. I don't even want to think about E55s as they have almost twice the mass plus the five-link suspension in the rear and multiple control arms in the front.
If you have the spring rates you could compare them to what SICAMG has on his car.
Would like to see you resolve this so you are satisfied with your E55 and can share it with others.
Hell the tires could be to far out and that's what is happening.
Or there is so much stuff in the trunk that the extra weight is an issue, but still with the shocks set on the highest number it should ride like a rock !!

You have something seriously wrong because that's 1,000lb spring in the front and a 900lb spring in the rear.
I run 1,000lb as an upgrade from the 800's it came with and it is "stiff" when set on "kill" adjustment.
Rears same thing, and 800's are more then enough so I think you are chasing something outside the box here..............
We need far more information on where your shock settings are.

Rear shocks are at max hardness unless they have this adjuster backwards and it’s on max soft, I have no idea but going to try the other way adjustment and see if that’s possible. The front is perfect no issues there
How about completing the subframe repair and then evaluating...My e55 tail really wagged when the bushings were shot. You mention they need it so start with the knowns IMO.

That is going to require some time which at the moment I do not have. But you are right! I am just trying to figure out if I want to keep the coilovers on or go back to airmatic. Maybe the rear slapping everywhere is due to my rear shocks being shot? I just want to be sure so Im not doing double the work when im in there.
On a separate note, don’t want to post another thread so I’ll keep it all in here.
OIL LEVEL NOT SHOWING
Just did an oil change (AGAIN) bcuz my drain plug was leaking and also replaced oil level sensor just for the hell of it. It’s been sitting blank like this for about 15 minutes
