Suspension upgrade

Bodyboarder,

When I bought my Z4MC in 2012 hardly anyone on this forum swapped the OEM suspension because at the time, most were raving about how great OEM suspension and handling was! I intended to change the OEM suspension to adjustable suspension from the outset. At the time I bought my car, a former owner off this forum was selling a set of AC Schnitzer Racing suspension on Pistonheads when he sold his car and the suspension had only done a couple of thousand miles. The suspension remained unsold for about 2 months so I decided to make a ridiculously low offer for the suspension and it became mine. The suspension was like brand new.

I have KWV3 on another car and although I would've preferred to fit the same to my Z4MC, the ACS Racing suspension has been superb. It's made by Bilstein to ACS spec. If you can pick up Bilstein PSS10 for a considerable saving on KWV3, then I wouldn't hesitate to buy it.

If you're wanting the car to perform best on the road, then I would advise to set the dampers at almost their softest settings at the rear and around their mid-point at the front. For track you can go as stiff as you like.
 
I've got the B12 kit shocks and springs. Love it. Corners better and generally handles and sits better. A tad more solid and a more 'lively ride', not recommended for those with neck or back problems...if that's the case get a Toyota Prius :driving:
 
!Calling all people with b12/pss10 /kw suspension!

any chance of a meet up and a quick passenger ride to determine if it’s the set up I’m after ?

I’m in Southampton but obviously willing to travel :thumbsup:
 
i have Clubsport track spec stuff... its really awesome , its just very stiff! lol. On track is blows my mind, and a smooth road it blows my mind, when its bumpy its kinda scary. i personally wouldn't recommend these given your intended use. These have turned it from a average handling car to something very special.
 
We need to meet one evening I have kwv3 fitted to mine more than welcome to experience them I'm in Southampton too.
They transformed the ride and handling had h&r and eibach springs with standard shocks before them.
Pm me you number bud easier to talk through WhatsApp.
 
Thanks Rob ( rally) for the very kind passenger ride in your lovely MR running the kw’s ..... now comes the hard part , justifying it in my mind that they are worth it for my needs :rofl:

What did you think? I never had the stock suspension on mine so only have the non-M to compare to. They are in a different league, damping-wise, but I still wish I had a bit more rear travel.
 
I’m also a very happy owner of Eibach Pro springs/oem shocks. In my view how the Z4M should have left the factory.
Will however put on the KW V3 kit in a few weeks, as I already have it. Will get back with my 5cents.

Yes I really liked them ..... but I’m struggling to justify the cost /hassle ! If I need to run 10mm spacers , that means running a slightly stretched tyre , so new Tyres , fitting , setting up properly... and so and so on !

Gets the flame suit ready ..... although I did think they are were very good , the eibach springs for the money are also very good indeed in my opinion, coupled with the new rear bush’s and limiter kit , I think I’ll be happy enough ..... I have ohlins on my s2k and again in my opinion are a step above the kw’s , so comparing the kw to ohlins I’m not sure I’d be happy .

I must be getting old as I’m starting to think more about these big purchases and if for my use they are worth it .
