Ok so I've measured my OEM ZCP and OEM non-ZCP suspensions... Here goes
The ZCP comes from a pretty stripper E92. The nonZCP comes with a pretty stripper E90. (No navs, no sunroofs, cloth seats). Both suspensions have around 30k miles on them In parenthesis you have spring codes and in the shafts, you have the shaft length until the 'shoulder' and then in parenthesis the shaft length to the top of the threaded section All lengths are in centimeters ZCP nonZCP F spring length 28.0 (X6) 29.0 (X3) R spring length 30.2 (X5) 31.0 (X2) F shaft length 13.3 (21.4) 14.2 (22.2) R shaft length 13.7 (20.2) 14.2 (21.0)

From your measurements I infer that the spring perches must be exactly the same height - does your tape measure agree?

I was not able to measure the perch height. My zcp suspension has gc camber plates whereas the nonzcp has oem plates. |

Couldn't you measure the opposite end? The bottom of the spindle mount area to the bottom perch?

I'm thinking of the bottom of the strut to the bottom of the perch would give you an idea if the perch itself is lower on the ZCP vs the Non-ZCP?

If it wasn't for all the arguing on the forums, I would've done swift spec R springs a long time ago.

This confirms that the perches are identical in height and the spring is the primary hardware that lowers it.

I'm at 103k and my suspension guy said all of my parts are in working order as if brand new. But I am curious as to why you are thinking ZCP will diminish as opposed to non ZCP or they will also? Hadn't looked at it from this point of view so I am curious as to why you think that.

I installed 2013 ZCP shocks and struts onto my 2008 non ZCP with H&R race springs, E36 m3 bump stops and new mounts (also for the 2013). The shocks worked with my factory EDC calibration, but coded the ZCP package into my VO shortly after. Coded euro MDM at the same time.
All of the parts are 100% interchangeable.

Are you thinking B12 with the EDC delete? I can only find the B6 and Damptronic for cars that want to retain the EDC.
I'm at 51K miles and looking to upgrade soon!

To retain EDC, you go B6 or B16.
B12, I think, is B8s (non-EDC) + Eibachs. But, B6 and B8 are the same, except shaft length, and B8s are only recommended when dropping ~1''+. So you can make the equivalent of an EDC B12 with EDC B6s + mild springs. A few are very happy with their EDC B6s with Eibachs (or Dinans, or Swifts) but others have admitted to being more satisfied with the OEM setup, especially if ZCP. I think the Bilstein stuff is a worthwhile swap as you approach 50K, but probably not an upgrade worth doing any sooner. To clarify my post above, the benefits of a ZCP car are the suspension and wheels (wheels easily changed). As cars approach 50K and need suspension overhauls, the fact that all parts are interchangeable makes the value of a ZCP car reduced (closer to a non-ZCP car). Unless it's a garage queen or collector, why would I pay much more for a ZCP car that needs a suspension refresh when I can get a non-ZCP car and get to the exact same point after a refresh, for less? Either throw ZCP hardware on the non-ZCP car, or go Bilstein under either scenario, whichever one wants to do, and after coding, the cars are identical.
