Has the rear subframe been reinforced? That would be the top of my list. When you take care of that you can also tackle the rear bushings and mounts easily, I have the Powerflex black bushings and the increased stiffness makes the rear of the car feel much more confident. If you can budget it, I would then replace your FCAs with OE BMW or Lemforder parts, that will significantly improve front end feel.

After all that then I would tackle the shocks and springs (unless your shocks are blown, mine were okay up to 130k). I personally recommend the B12 Pro kit as it improved the ride quality, gave the car a nice little drop (but doesn't scrape on everything), and significantly reduced the body roll that I hated. Get the Ground Control or Turner front camber plates and Rouge Engineering makes a great rear shock mount kit. If you want to see pics of my car check out my instagram, jaorugby1990.

Steering guibo...might be a hot climate thing but everyone I know local has needed them and it makes the front end feel 10x better. $50 "while I'm in here" insurance during all the other stuff. Prob throw some tie rods in there too if you're anal

Default Re: Suspension advice at oem 100k

my god... this list keeps getting longer, I'm trying to accumulate all of these parts and then get the car ready for the install. I was speaking with someone with an e46 m3 yesterday who seemed pretty knowledgable about these cars. He also mentioned rear subframe reinforcement. I believe this car has had the subframe done under warranty, along with Vanos, and rod bearing. I had the car into a bmw independent shop and they looked over the car very thoroughly and didn't mention finding any cracks. They did find broken rear springs however. The cars suspension feels completely shot, it has 108k miles and approx 70k of those were over NYC roads. The rear end seems to nearly collapse on bumps and make a huge thudding noise. I'm hoping Koni/Eibach setup will eliminate that issue and it isnt infact somehow related to subframe cracks.

Heres my current to-do list as it stands.
Springs/Shocks/struts($930?)
Spring Pads? ($50?)
Shock Mounts? anyone know a part number here?
Strut Mounts? (200 for pair?)
front control arm bushings($100?)
Rear trailing arm bushings($70?)
Flex Disc(the shop found a crack in my current one)($50?)
Steering coupler ($50?)

Is there something else imperative I should be adding to this list. (I'm not anal, but would like the car to be enjoyable to drive. Currently steering does not feel tight the car has a lot of vibration from the suspension, does not feel as fast as it once did. Considering changing out the sparks and coils.) Thanks everyone

Check that page for RSMs. For your needs, stock style are more than adequate despite people probably suggesting aftermarket (yes, I have aftermarket).

I think a lot of people let their suspension go 100k and then are upset the stock rubber parts are dry, cracked and/or torn, but they're actually very good for 40-60k.

Lemforder, febi/bilstein are good brands. Reinforcement plates are a good idea as are new paper gaskets.

If you're gonna go through the trouble of doing the flex disk on the drive shaft I'd do the center bearing while you're in there...chances are its seen better days and you gotta do the same shit to replace it as the flex disk.

ECS has steering coupler for $50 and I bought new bolts because I'm anal and have a bad habit of breaking shit (another like $15)

They also have a kit for guibo/center support bearing for like $200 iirc

Having a new subframe installed is not the same as reinforcement. Make sure to add reinforcement to your list of things to do, and inspect it one more time right before any work is done.

Is reinforcement something I can DIY? I've done some reading up/ youtube clip watching and I see some kits out there. If there are no cracks does it still make sense to do reinforcement?

We have pot holes large enough that your cars body will bottom out if you hit them (fall into them) in the late winter/early spring.

But we have millions of cars and heavy trucks. It's probably worse up there, but you should see what 30+ million people living in 40 square miles can do to infrastructure!

Just installed Bilstein B12 Sport Kit, love it.
- For rear shocks bought Ground Control mounts.
- Purchase front/rear sway bar links, one of my rear ones broke.
- for fronts buy axial bearings, they will be shot
- while installing fronts be careful not to snap xenon leveling sensor attached to the front control arm.
