I bought some Koni Yellows and Eibach Pro kit as well and switched them from the crappy BC coilovers and replaced all the strut mounts, coil spring perches, bumpstops etc etc. I took the adjustable end links off the BC coilovers and replaced with my old stock sway bar end links. It rode beautifully for the first 5 days until about 500kms worth of use on them then the front starting getting clunky and rode a bit harsher and bumpier than usual. The rear still rode absolutely fine. I jacked up the car and saw the old stock sway bar end links had black fluid leaking out of them. So I replaced the sway bar end links with Meyle HD sway bar end links, and the clunkiness was gone and the ride quality was very noticeably better and was back to normal.
Look at your sway bar end links as well. |

Yea I guess I will have to make adjustments to the shocks. I just wish I didn't have to removing the shocks every time. I wish their was adjustments like the front for the rear. |

Has the car been in any wrecks or hit any huge potholes? I would have someone inspect all the components in depth and see if anything is bent or needs replacing. Subframe bushings wont be a cheap job but if it's something you were going to do at some point in the future anyways, then go for it.

Today I installed the whiteline inserts. The install was fairly easy. It almost took more time to get the car on and off the jack stands. I was trying to document the process with pictures, but of course my phone died. The car feels much more stable in the rear, but still bouncy. I am going to keep tweaking the dampening to get it perfect to my liking.
Now that the rear is almost there the front needs to be addressed. I installed new koni struts along with new end links. I seem to have minor vibration in the wheel over 45mph. The control arms look okay, but I am guessing the ball joints are probably shot as the car has 57k miles now. M3 arms are everyone's choice so I'll probably go with them. Would you replace the tie rods at the same time? Hopefully after this the car is stable at high speeds and I want to do some rolling races next spring.

So I took the car to one of the local well known BMW shops to have them look into the car. I told them it didnt seem to ride smoothly whether the dampening was full soft or full stiff or anywhere in between. They looked it over and said everything in the suspension seems to be okay and recommended an alignment. I got the alignment, but the car still does not ride smoothly.
Maybe I am just way to use to the old e36 suspensions because neither stock suspension or coilovers felt like this car does. Like I said earlier it seems like a low speeds I am riding on octagons rather than circular tires. I have moved tires front to back and side to side and nothing helps. I am about at my whits end with this cars suspension. |

Brand new DWS. I have taken it to 2 shops and they have said everything is fine. Maybe its all in my mind, but I swear something isn't right.
I am trying to get a local 335i to let me ride with them and see the difference. |

has the rear subframe bushings been changed? I'm starting to get some creaking sounds and a bit of extra harshness when I go over big bumps on road at low speed from the rear end and on inspection, it can be seen the bushings are heavily cracked at currently 101k kms. Either gonna change to Nolathane rear subframe bushings or save up for the m3 ones.

I ended up buying the aluminum bushing from Turner. They should be here Saturday, so I will probably get them put in over the weekend. I went with them because the new M series have a solid subframe and ride well. Hopefully the combination of this and adjusting the dampening fixes the ride quality.

I'm thinking it's in your head too. You're on stiffer springs with stiffer shocks. You're going to feel a lot more imperfections in the road and the car is going to react to the smaller bumps that the old stock suspension just absorbed. Especially at slower speeds.

Yeah i think so too. I need to sit in a very low mileage 335i with m sport suspension to know for sure. But the Koni Yellows are a solid package.

I assume that for every suspension arm replaced (if any) that you torqued their bolts with the car at normal ride height? If the ride height was significantly lowered, these should be reset since you don't want the bushings to be wound up at static height. (i.e. see the thread on the effective spring rate the E9x rubber bushings have)
Second thought is, again if the car is lowered a fair amount, what about the bump stops? Do they need to be substituted for shorter/stiffer ones or simply trimmed? You could possibly be getting into the bump stops on a regular basis. Anyway, just a couple of random thoughts to maybe help the troubleshooting process.

Bought Turner aluminum bushings for the subframe and couldn't get them to go in not matter what I tried. Sold them to a buddy and now I am getting the AKG bushings 95A for the subframe and hope those go in a little easier. My back end moves around way too much. Make my passengers think the cars suspension is shot ha

I bought AKG subframe bushings and put them in. Getting the original bushings out was a PITA, but the AKG bushings were so simple to get in. I have noticed that when I punch the gas now the rear end stays planted! Back to the ride quality, I cant seem to get the car to ride smoothly. From soft settings to firm doesn't see to change how erratic the car rides. I guess the next thing to do is get road force balancing done, but I don't think that would help suspension oscillations.
