Default Suspension advice at oem 100k

Hey all,

Picked up my car a couple of months ago from a friend. It's in a state and needs some work. The suspension is completely shot and I plan to go for the Koni/Eibach setup. The back has a huge thud on medium to larger bumps, the front feels very loose and not what I've come to know on an M car.

I was wondering while I have the car in the shop on the lift if there are any other refreshes you would recommend at the 100 mile mark on a largely all original parts car at 100k miles.

I think I will also be doing the control arm bushings. Are there any parts I should consider to go along with the Koni/Eibach setup like mounts, and which would you guys suggest?

Sway bars? its an 02 should i consider a front strut brace? Any advice appreciated. Thanks.

Front control arm bushings, rear trailing arm bushings and check ball joints for play!

Is this a budget fix or a replace it all thing?

I'd do Koni Yellows and stock everything else including Springs.

A pro kit would give a subtle aggressive look. I would def drop a tiny bit atleast. No 4x4!

ECS has kits for front and rear, BMW or one of their pieced together kits. I've heard you can call and sub for different brands with the kits ECS puts together

I don't think you need to do the ball joints unless this is a hobby and $ is not an issue AND you enjoy torturing yourself (fun with the picklefork on the fcas). These ball joints go a long time - mine were fine at 140k but I changed them cause I'm anal.

I'd simply do the fcabs/rtabs, RSMs, spring pads, top hat bearings, shocks, springs. Pull the strut mount pins.

All stock mounts are very good, maybe do limiters on the rtabs. I also would suggest CSL, Dinan or Eibach lowering springs.

Thanks for the advice everyone, looking at front and rear bushings, I know people recommended the Meyle bushings on here. They go for $70 for the fronts and $50 for the rears. Do i need the whole kits? Should i go for just the oem rubber bits and try to swap them into the existing metal brackets?

https://www.fcpeuro.com/products/bmw...-31126757623my

https://www.turnermotorsport.com/p-3...6-e46-z4-pair/

Does anyone know the part number for the strut mounts and spring pads?

I'd like to get the car slightly lower for a more aggressive look, interested in a set of apex, i like these new FL-5 with the lip, more aggressive than the oem 18s

Very dependant on roads and driving. I have done Drivers at ~ 80k miles passenger at ~100k miles and now just had to do the drivers again at 140k miles.

I didn't take cold climates into consideration, so that's possible.

But I don't agree about driving and roads as I beat on my car and roads are not that smooth here.

You're welcome. I would only use Lemforder as the OEM choice if not going with genuine BMW, personally.
