A local member who does this in his spare time did the work. Well, to be fair to myself, we did it together. It is not not as easy as other cars I have changed the suspension on, but it is doable if you are mechanically inclined.

For some reason BMW designed the F10 to sit very high and even the M5 looks a little lifted to me.

I hope this helps.
+1

ACS is great and my dhp still works fine. MUCH better handling and even looks.

I hope that helps.
Is this 1" drop from M-Sport suspension or standard?
I dont have M-Sport on mine so I wonder how much it wil be lowered. It is higher front than rear which looks really stupid, but thats all F11 touring cars.

I don't have the M Sport, but I have the Sport package. I don't believe there is any difference in height with those packages though.

Completely gone. I believe this was an ACS issue...

Now I just have to find out which shop here in Jakarta does a corner balance..
One shop in West Jakarta area claimed that they are one of the experts in wheel alignment business here. I'll call them up tomorrow to find out...
Seems authorized coilover dealers here just do sales and marketing (and basic installation) and doen't bother to do a corner balance...

I wonder if someone could chime in on the V1, V2 might be overkill for me if I don't plan on adjusting it at all.

Interesting post... After installing the ACS, we noticed a wierd sound coming from the dash-back engine area. Would notice at slow speeds,hitting bumps or uneven road.. Took it back to shop and had them retighten and check everything.. Noise still there, looked at every option for the noise and never found anything??? Does the noise you all are hearing sound similar to this?? I have actually just tried to ignore it since, but this noise issue makes me curious...

from my understanding after a few days of combing google, seems that for daily driving the v1 is sufficient given u drop your car to kw's recommended height. but if you want more comfort than the street comfort is the way to go. basically kw street comfort is a v2 with softer spring rates and linear springs (v1/v2/v3 are all progressives).

any track junky please correct me if im wrong: progressive springs are better suited for track use while linears are better suited for daily street driving
