Default Suspension - Koni Yellow (what springs & settings?) E46 M3

Hi guys!

My M3 E46 coupe currently has AC Schnitzer shocks & springs (unknown millage) and ground control street camber plates.

Its not a DD (street use only) but i want a comfort set up with a slight lowered look compared to stock and like oem handling.

Also installed a front sway bar (H&R) and I want to try some CSL bushings to see if things soften up a bit or else I will put the stock arb back.

Car is on staggered oem 18s and Apex square 9.5 255/40/18.

I ordered a set of Koni Yellows and expecting to have them in July.

Should I keep my ACS springs or get a new Eibach set?

I will also keep the camber plates.

I was reading some old threads and I read that with oem springs they set them at full soft where others say that koni doesn’t recommend setting them at full soft.

Any info on the settings?

Are you replacing the ACS shocks because you find them (and/or the springs) to firm?
Or are the shocks worn out?

And are you happy with the ASC ride height or not?

Maybe you can find out who made the springs for ACS? Could be H&R, for example. You might be able to figure out srping rates from there.

Eibachs are the best aftermarket spring maker, imo, so you couldnt go wrong getting a set to match with new Konis, then run the konis full soft, tightening them a quarter turn every 5k-10k as they age. My suggestion.

Bought the ACS suspension from a friend 1.5 year now (unknown millage). It is comfier than B6s & oem springs that came with the car when i bought it + a slight lowering. Body roll was more with the ACS. (thats why i installed a front H&R arb)

I would like to do a suspension refresh because the shocks are worn out.
Wife is pregnant and she sometimes uses the car also.
Iam currently happy with the height (even though i might move to a new house and the pro kit might be better cause it might be a tad higher).

I dont know the rates of the Schnitzer springs mate and how they will work with the Konis.

Then I'd keep the ACS springs and set the Koni's at somewhere between 1/2 and 1 turn at least.

As your adjusting rebound it gets more composed, within reason of course, moving away from full soft. Otherwise you'll probably find in bouncy.

The problem is that you have to remove them to change settings.
Can the fronts be adjusted on the car when you have GC street camber plates?

Yes, the fronts can be adjusted on the car even with those plates.
The standard rears will, as you said, need to come off. But thats not a big deal if you leave the trunk lining loose.

I had the top adjustable tear Koni's. That's certainly easier.

i had 1/2 turn from soft in the rear, and 1/4 turn from soft in front.
you can then tweak the front to suit your driving style, while the rear is a pain to adjust.
i had eibach springs too

Rears aren't bad - don't even need to remove the wheels. Pop the limbers back, raise the rear up just a bit and pop them out. 30 min job.
