M-Adaptive Suspension - Bouncy / Wobbly Over Bumps

53K Miles on DASH

Stock everything in terms of suspension components..

So every time I am on a bumpy road ... the car feels extremely wobbly and bouncy sorta speak on all 4 ends...

Does this mean bad shocks??

I was thinking of shockware to fix this.. but i might just get coilovers or something at this point..

Could be.

Tires make, model and size?

Tire pressure?

Wheel size?

What mode?

XDrive?

Lots of unknown variables, though I have yet to hear of anyone regretting a shockwave purchase.

How does the car behave when the suspension is in sport mode?

Tires:

Continental ExtremeContact
235 35 19 in front ( I think)
265 35 19 in rear

Installed about 1500 miles ago


Car does feel a tad better in sport but still has a slight bounce feeling when rebounding

Comfort mode with M-adaptive was pretty useless IMO. Sport was somewhat bearable, but still felt like you were settling for sub-par. Shockware fixed that.

Continentals do have a softer feeling than other tires IME. You try increasing your tire pressures?

I'm at 36psi in front and 40 psi at rear...

I just don't want to invest in shockware and still not be happy :/

That's a little high on pressure from what I run, but that wouldn't contribute to your shock rebound behavior. My door says 32 front 35 rear, I would check your door and run that or within a couple pounds of their spec.

I would be hesitant to put money into potentially spent dampers. Your description of floatiness on rebound is the best indicator for shock life short of taking them out and inspecting them. My passive 704 dampers were spent around 55000 miles, on the road they were very floaty, on inspection they had little to no rebound. YMMV with average road surface quality and how aggresively you drive. Shockware will increase their wear rate, dramatically if they are already in part compromised.

If you say that you're interested in coilovers now is the time to see your options and what is most appealing to you. Most people who go this route choose passive dampers, so if you do shockware now and decide later to upgrade to coils, you'll be out that plus the cost of an EDC deletion kit.

All this being said, if you have confidence in the condition of your existing dampers, shockware has satisfied a lot of members on this forum.

The shocks are most likely in the range (based on mileage) where their useful life and performance begin to degrade.

With M Adaptive suspension, the choices are:

- Replace OEM adaptive shocks. Add Shockware later. Or wait for Bilstein to release long awaited PnP Damptronic shocks for EDC equipped vehicles.
- Replace with passive coilovers and add EDC delete kit.

Thank you for all the info!! This is where I get stuck now and don't know what to do lol

I really like a comfortable ride but firm at the same time....

I like the adaptive idea but can't find any replacements that won't kill my bank lol

Idk if I should get cheap coilovers or look for used adaptive shocks

Why not try Shockware? It's not very expensive, and it may give you what you want all by itself.

I'm thinking my shocks are bad at this point because I drove my friends 328i with stock shocks and it felt planted and firm without being wobbly
