Hi,

Yes, it seems B6 DT is not a happy compromise for comfort, even more so when taking into account I'm riding on 225/45 R18 NON runflats.
It's likely that comfort on 19" or 20" wheels, or runflat tyres, will be worse.

Before trying B6 DT I had Bilstein B16 PSS10 Comfortversion installed for a very short while. These dampers are not controlled electronically; damping force can be changed through a wheel underneath the dampers. I haven't mentioned this because that's not the subject of this thread. Anyway (long story short) : the springs that are included in the B16 PSS10 set helped me decide to go back to the original springs.

So, to clarify, I went OEM -> B16 PSS10 -> B6 DT -> B4 DT.
Yes, I know, I spent some dough looking for a suitable suspension system.
But hey, you only live once. And , I've learned a lot.

Cheers,
GSband

Would you say the B4 in 2nd position is a noticeable difference/improvement over stock? I would like to pair it with the MSS HAS:

https://shop.mss.company/shop/mss-sp...ies-f22-coupe/

Some more information on the MSS kit

https://www.2addicts.com/forums/show....php?t=1650208

They are really popular with the 1 & 2 series crowd.

Hi,

OEM variable dampers had a huge spread between pos 1 (comfort) and pos 2 (sport). Perhaps for marketing reasons ("I can really feel the difference"). In pos 2 the car would just bounce up and down. Pretty useless if the road isn't completely flat.

On B4 DT the difference between pos 1 and 2 isn't that big.
Pos 1 is more sporty than OEM pos 1, while still comfortable enough.
Pos 2 is less sporty than OEM pos 2, so the car doesn't bounce, I'd call B4 DT in pos 2 sporty-efficient.

Sorry, I can't comment on MSS products. It took me some time already to describe the suspensions I've tried out. I'm not gonna venture into comments on products I don't know.

Cheers,
GSband

Very interesting reading the experiences of someone who has gone through OEM, B6 and B4. I have experienced OEM adaptive (which maybe tauter than non Mlite cars? Certainly different PN's) and now have B4 Damptronic dampers. No experience of B6'. After all the reviews of harsh ride with B6, decided to go B4, but I can see how a B6 would yield a very sporty handling. For me I too wanted a compromise for comfort and the B4's for me address the shortfalls of the OEM shocks. It seems reviews of the B6 DT's are rather subjective as on a UK forum some have said they are more compliant and comfortable, but sporty and handle really well. Perhaps they are used to a fast road setup. I sometimes wonder if I should have spent a little extra and gone with the B16 damptronic kit for height adjustablility. I guess one can add MSS springs to get a similar effect with B4 DT, albeit without being matched springs.

I went to visit MSS in March and test drove their M140i. The springs where remarkably compliant considering how low the car was on passive OEM shocks.

Recently replaced the OEM adaptive dampers and springs on F36 440i RWD.

Went for the B6 Damptronics with Eibach pro springs and F8X bumpstops.

In comfort setting the B6 are definitely stiffer but more compliant, before it felt like a boat, too soft and bouncy.

In sport setting it's quite harsh on the UK roads but still manageable.

I only use the 440i as a weekend car so it works for me but I could see it being hard work as a daily driver when in sport.

Standard OEM dampers and springs.

M140_BCS, thanks for sharing. Great car, by the way!

To what extent do you think Eibach Pro springs contribute to a harsher ride in Sport setting?

Thanks.

Not too sure on the Eibach pro springs making the ride any harsher in sport, possibly a touch.

Current B6 sport setting feels similar to the Bilstein B14 coilover passive setup I had on a previous F20 M135i.

Think I would have gone for the B4 Damptronic if buying new after reading the reviews but I got the B6 used for half price with a few hundred miles covered.

Agreed, your 440i looks lovely! The rear end is so much better than the 2 series! Miss my old E92 335i for the shape. Your Eibach springs seem to give just the right amount of lowering and a level stance. I had Eibach Pros on my e92 335i and there was more of a raked stance.

Here is my car with B4 DT and BMW M Performance Springs:



OEM vs B4 DT:

Thought it might end up with a raked stance but sits well, big improvement over the standard 4x4 look.

Last on the list of mods is some decent aftermarket 19s. One of the rear 442M has started with white worm under the clear coat from round the centre cap...

Possibly looking at BBS CI-R or CH-R?

I agree with you on the E92 335i, had a few of them over the years.

Great looking cars.

Are the oe bump stops needed when replacing with B4s? I've seen conflicting info on whether they have internal stops as the B6s do. Any harm in keeping the oe even if they do?

Edit: They are needed with B4s, confirmed with Farkle.

Did you have to get an EDC cancellation kit? Also, did you consider trying just the springs first, I've read many posts stating that the Eibach springs work pretty well with adaptive dampers and you also retain the adaptive suspension. Some of them also supplemented it with Dinan shockware.

Used to have ST lowering springs and not too happy with stock EDC dampers, perhaps Eibach are better suited but i doubt they differ much.

Now on Koni sport non EDC dampers and damping force is well matched with springs, much better

Looks like people have had good results with Eibachs and Dinans paired with adaptive dampers, I think Eibachs mostly. I was looking for Koni and Bilstein for my car but Bilsteins were back-ordered and Koni does not make dampers for 4 series xDrive. Ended up with KW V1. I did not have adaptive dampers though.

No cancellation kit needed. Replaced the OEM adaptive dampers and springs with B6 Damptronic (Adaptive) and Eibach pro springs.

Considered the Eibach springs on OEM adaptive dampers but found a set of B6 adaptive dampers used so went for that setup. Impressed so far!

GSband how you finding the B4's?

I've done about 1500 miles on mine and i have to say I'm a little disappointed in the compliancy over small sharp bumps, I get quite a bit of rebound thud through my strut mounts. Perhaps this is due to the M Performance springs not matching with the B4 shocks gas pressure. Never had this with OEM adaptive with M P Springs. Things do tent to soften up a little bit after driving for a while, but not much. Perhaps my lighter 2 series plays on this too. There is no doubt the B4's make the car handle better and there's less lean, I guess that's at the compromise of a little comfort.
