Not had a chance to give it loads on corners yet but very impressed with the comfort on crap roads. Booting it from a standstill it had no rear squat and squirming from side to side, just good grip and composure. It is a big improvement and just wondering how it stacks up against the adaptive system.
The adaptive system gives a slightly broader range of options over the passive, but ultimately it’s still cheap crap that doesn’t belong on a BMW. You have a significantly better system as you will enjoy finding out.

Went for a fast blast over mountain road yesterday and it's vastly improved didn't even see the traction control light come on. On slow badly surfaced urban roads it now thumps and thuds where before it would bang and crash, if you understand what I mean.

Thanks for the feedback, and your previous comment on less squatting and squirming under hard acceleration, that is one of my pet hates. I definitely need to get some, but apparently there is a shortage of dampers for the kit I have been told and they are on back order.

How do you find the ride height compared to standard? Hopefully not much lower...

Ride height on mine not visibly noticable, just measured it compared to standard and it was down 1/4" at most.

Bilstein B12 questions

Post by DanT » Mon Jul 30, 2018 6:19 pm

Hello All,

Ive recently had Motech fit basically the B12 kit to my M135i using their Eibach springs that drop 25/20mm. From what Mike said I was one of the first to have this combination fitted.

Since fitting I have done about 1300 miles now and I have to say I am impressed. The floaty rear I hear some guys mention has pretty much disappeared. With regards to better handling, yes I can confirm it is better. The standard car does have a great level of grip, but getting there, the car used to feel a little unsure in itself if that makes sense. With this kit fitted, that problem is gone. Change of direction the car is a lot more sure of itself, less body roll helps I guess, being a little lower etc etc.

With regard to comfort, this kit has literally no increase in harshness in any situation compared to standard. It is as you would expect significantly better damped, bumps I used to feel on roads with the car standard are ironed out better with this kit, much more controlled, firm but a comfortable firm if that makes sense.

With regard to alignment, I would recommend getting this done after 1000 miles, I did. Previously my car was aligned on a hunter alignment rig to factory specification, this was late march this year. After the 1000 miles and no knocks or bumps between the first alignment and the second, it did need doing again. I expected this to be case anyway and would have had it checked either way.

Everything went back to standard specification, previously I had camber of negative 32 minutes front passenger side and negative 41 minutes front driver side. After the recent alignment I now have negative 1degree and 8 minutes front passenger side and negative 1degree and 1 minute front driver side. The second alignment I should point out was done on the same hunter alignment rig as the first and was happy to see the extra camber, although some would argue it isn't enough to iron out the sidewall wear/give the best increase in handling, but I'm still happy to see over 1 degree on each corner. Everything else went back fine. No extra on the rear, about negative 1degree and 40 minutes each side.

Just thought id share that for anyone who's interested.

Good feedback thanks, and useful comments on the geo set up. I think the motech springs are a bit low for me. How much was it to supply and fit with them? Might ask of they can do the standard eibach springs.

Hi all, I am watching this with keen interest as I really want to either change the suspension on my M240i or I will have to get rid its that bad.

Obviously B12 has great feedback but I am trying to find out more about some other options I have through some connections. I have the option of the more expensive KW V3 and the Bilstein B14 for very reasonable amounts. Just wondered if anyone has any feedback on these? Thought i would start here and then if need be start a new post about it - I am very conscious that suspension has been done to death!!

Has anyone tried the Bilstein B4 or B6 damptronic for the adaptive cars? It’s already in their catalogue and with prices...

I think Joe Achilles had one or other installed yesterday at motech - definitely bilstein adaptive.

Joe had B14's installed at Motech on Friday. Waiting for a YouTube video of his thoughts.

Did you specifically ask them to dial in a negative camber of 1 degree on the fronts or is that just how things came out when you had your most recent Hunter alignment done ?

I've definitely had the outer sidewall/shoulder wear on my front MPSS but have ordered new MPS4's with a slightly higher load rating of 92Y (rather than 88Y) hoping that might help. I'm having Hunter alignment done at the same time as new boots and wondered if I should mention anything about dialing in a little neg. camber or just let them do their thing...

Hey there,

I didn't ask them to dial in any extra, this was how it was when it came back to me after the alignment of everything else.

Would recommend the kit thoroughly its a genuine upgrade over a springs only solution.

Camber on fronts is not adjustable. Only Toe.

You need aftermarket solutions to give more camber. Having said that the - ve camber is higher on the m lites than most cars.
