Koni Special Active Shocks with ACS springs 335d xdrive
I've just had ACS springs and Koni Active Special shocks fitted after having the stock suspension setup on my 335d GT Xdrive since owning the car for nearly 3 years. My main reason for changing the suspension was to have a tighter feel to the car and to improve handling on the Norfolk b roads I drive on daily. I also wanted to maintain comfort levels as best as possible so after lots of research and almost going for a different setup I decided on the Koni SA + ACS combo... I haven't yet found a thread reviewing this combo.
I have only driven around 10 miles and everything needs to settle a little still but my immediate impressions are good! The drive is actually more comfortable as bumps are really easily soaked up and so far feels better than stock. The steering feels more responsive too. I haven't tested at high consistent speeds yet but will update you on this after a couple of weeks. The car looks lower to a point where it looks good (very subjective I know) and not slammed at all, I was almost expecting it not to look as low as it does but to stay close to stock height so that's a bonus. First impressions are good. Turns out my front left shock was on its way out as it was leaking oil so I'm glad I got this done.. I had some issues a few months ago with noise from the front left wheel area and steering wheel judder under heavy braking which led to me needing to change my front set of lower wishbones which alleviated the issue. This obviously had a negative impact on the shocks which was missed at the time. Very pleased I had them changed! I also had a back box delete with twin single exhausts fitted

Thanks johnung, I did see your posts about the Koni / Eibach combo which was definitely helpful in my decision. As you know the advice is not to use lowering springs with these shocks if they are too low; I was advised nothing lower than 30mm. However mild lowering springs are ok such as some of the Eibachs and the ACS ones. Lorcan advised the ACS ones are within the 30mm tolerance so it was a no brainer, especially the ACS springs were on offer at the same price as the Eibachs!
The car does look lower than I thought it would, surprisingly similar to ACS + B8 combo pictures I've seen on the forum... I'll have to measure the tyre to wheel arch distance to see. Does your setup look similarly low as mine johnung? I have a feeling you have 18 inch rims which will obviously make a difference.... |

I ran these on my wagon before, just with Eibach springs (Eibach manufactures ACS springs)
I have to say it was a great setup, they definitely do stiffen up with harder jolts/cornering, but are smooth and compliant on normal roads, best of both worlds. |

Out of interest, have you changed your suspension setup?

When I did the Koni struts & springs I ran 13mm spacers. When I got my alignment checked it was still within spec kind of surprised me.

How do the coilovers compare?
That is surprising! Is 13mm the minimum you can have on the rear due to the lip on the wheel hub? I've read this in various places... Final question! Which spacers did you go for?

Farkle! has posted a lot about the stock spring specs which effect ride height and aftermarket spring drop. |
