CONFIRMED: Bilstein Dampers for Adaptive F2x

Post by mouse140i » Tue Sep 04, 2018 1:03 pm

I went old school and picked the phone up. Spoke with a very helpful chap at Bilstein Technical UK (https://www.bilstein.com/uk/en/about-us ... d-contact/) and he clarified the situation.

There is a full Bilstein Coilover kit in development and will be along the lines of a B16. No date for release but there is a product code out there.

B6 damper for EDC is available and works well with either standard springs, H&R, Eibach standard or Motech Eibach (a bit lower than Eibach standard).

Parts required as per another post :

1x Front Left : 23-250727 http://www.bilsteinsuspensionstore.co.u ... 598667.htm
1x Front Right : 23-250734 http://www.bilsteinsuspensionstore.co.u ... 598668.htm
2x Rear : 20-250744 http://www.bilsteinsuspensionstore.co.u ... 598666.htm

Simple plug and play. He said normal setting is a little harder/stiffer than on standard dampers if used with standard springs.

Linking back to other posts I can remember and other people who have queried or done some research.

Hopefully this answers a few questions!

Nice work, just come across this thread. As you've noticed, I've done some research in parallel and like you today got a reply from Bilstein via email confirming what you state above and they are in stock ready for delivery and compatible with my F22 M235i. I've yet to hear back from them regarding whether shortened bumpstops are needed (probably spring dependant), whether EDC coding is needed, i.e. M Performance option 'SZP5A', again probably spring dependant.

I wonder if they will also work with Vogtland springs. Personally would want minimal lowering.

I've found kmspartsonline on Ebay sell these shocks and I suspect www.spring-loaded.co.uk will be able to get these too. I've used spring-loaded before and those guys are very knowledgeable.

So looking at ~£1538 + fitting + Springs (if not using OEM M Sport springs).

Bilstein guy said standard Eibach don’t drop too much and that was why Motech had theirs developed - to give more drop that some people wanted.

Another alternative could be the BMW M Perf springs on the B6 dampers as they offer a minimal drop.

I wasn’t told about any additional coding. Everything plugs in to existing cabling and works.

Might be wrong but I got the impression from skim reading a Facebook post a week or so ago that Joe Achilles has had them fitted to his Motech M140

All true. I spoke to Mike at Motech when I had my springs and spacers fitted a few weeks and he briefly showed me the new dampers which were due to fitted to Joe's car. I saw from his IG feed that this has now been done so just waiting for his vide/thoughts to drop :)

Yup, found it here, although he suggests they're the B14 model?

Fantastic, eagerly await his thoughts on them then! (Love his videos)

@moise140i thanks, I've previously had Eibach spring on FSD Koni shocks which were fantastic on my e92 335i but didn't like the raked stance at all. Motech eibach i was interested in, until i saw how much they drop the car.

Yes 10mm M P Springs or 15mm Vogtland for me i think. MP are £411 so expensive. Vogtland springs are about £137.

They look like B6 damptronic to me, but i could be wrong

Are there any springs that don't drop the car at all? I'd like to improve the damping whilst retaining adaptive but I've got the MP splitter on the front of my 240 and it's low enough as it is, so wouldn't want to drop the car at all really.

I have the M Performance splitter too, hear what you are saying, it is low anyway and with speed bumps etc can be a concern. You can always just get the B6 Damptronic shocks and keep your standard M Sport springs, that will keep your ride height the same and presumably improve the damping.

EDIT: you could always even buy the B4 Damptronic shocks, these are OEM replacements, but could improve on the standard Adaptive shocks. Part numbers are: 23-238916, 23-238923 & 20-238933

If you want stiffer springs, I believe the only option for minimal drop is the M Performance Springs from BMW which are a 10mm drop over the M Sport springs. I suspect 10mm would be ok with the M P splitter. I read that H & R and Vogtland supply 15mm drop springs, but i've also read that the H & R spring rates are softer at the rear than std springs.

From experience though, (and it seems hardly anyone seems to consider it or talk about it), when lowering a car you need to use adjustable drop links to the anti-roll bar. Perhaps these aren't needed for the M P Springs as they are only a 10mm drop over M Sport l, but anything below that i would say you need adjustable droplinks otherwise there will be preloading of the antiroll bar and as I found out new droplinks will fail very quickly even on a conservative Eibach Pro kit.

Anyway I digress from the subject of shocks..

Yes - either retain stock and upgrade dampers or talk to Birds BMW as their B1S/B2S springs have a minimal drop or if running an M135i, fit stock M235i springs.

So looking at ~£1538.
Coding - none required - swapping hardware has no impact on variable damper control [VDC] module. However, speaking from 1st hand experience of having my Sept 2013 M135i VDC SW updated - latest OEM VDC flash is a vast improvement, for pre-LCI cars anyway...

Price - potentially cheaper ie £150-£200 cheaper via this Oscaro site:-....

Left front €410 https://www.oscaro.pt/pt/amortecedor-de ... ?vid=47466

Right front €424 https://www.oscaro.pt/pt/amortecedor-de ... ?vid=47466

2 x rears €634 https://www.oscaro.pt/pt/amortecedor-de ... ?vid=47466

Wrt bumpstops, AFAIK front B6 struts are monotube type so no external b/stops required whereas rear B6 relay on external bumpstops. So, if also fitting springs with more than 20-25mm drop, I'd suggest shorter rear bumpstops - lots of info on here already just go search....

Cheers chaps, whats the consensus on the standard spring rates and how do they compare to quality aftermarket spring rates? To me the standard car feels a tad overly sprung at the back regardless of whether in Comfort or Sport etc but that may just be the lack of quality damping

Correct - stock rear setup has overly stiff springs and fairly flimsy [in terms of torsional stiffness] ARB.

When birds originally fitted H&R sport springs to my pre-LCI M135i they concluded H&R spring rates were up on stock by ~ 25% front and down by 5-8% IIRC in the rear.
