Great post, thank you for adding to this thread!
So to make sure I'm understanding this right: the increased height to a ZCP car is not caused by the "spring perches", but rather the increased pressure and "push" of the new Bilstein dampers?

regarding ZCP car - mine is non-ZCP, and as I fished around the threads I've seen a lot of speculation but no hard evidence of exactly the source of the 10mm lower ride height on ZCP. Since most of us have only one M3 we don't have the luxury of putting the parts side by side to compare. Without my own clear knowledge of the ZCP spring perch location I don't want to make an incorrect statement there. But there will be that quarter-inch or so lift from the shaft force on top of any difference that may or may not arise from spring perch height differences.
Probably the best advice for using these shocks is Lufty's - use them with Eibach springs which will be a lot like stock ride and ZCP height.

I was considering this. I changed my mind though. The OEM ZCP damping is actually pretty good. I would go with the GC setup. The OEM ZCP EDC front struts can be had now for just under $600, a little more than the Bilstein shocks.
I have seen great results with the GC setup. I will just get new dampers when mine wear out. I am at 30k miles so far and probably just at the half way point of life in the OEM dampers. Dave

I, for one, would love to see some measurements to compare if there are differences anywhere.

I'll try to measure in a couple days. Both suspensions are just sitting around so it shouldn't be too hard

Seeing as I bought my E90 ZCP with 62k on it, can anyone compare FRESH OE EDC front struts to Bilstein B6 Damptronic front struts??
I've already installed the rear Bilsteins, and have a set of Eibach springs on the way. I'm currently sitting at 71k. So...assuming the Bilsteins come back in stock next month...Fresh OE or Bilstein B6 up front...opinions??? TIA -Mark in St. Louis |

To be honest, the OEM ZCP EDC shocks are excellent. Issue is if you go to a much firmer spring there may not be enough damping. If you go with a 10% stiffer spring the OEM ZCP shocks are fine.

Considering the persistent and extending backorder on all things Bilstein I'm now leaning toward just a fresh set of OEM shocks. Wondering if there's any value to replacing with ZCP shocks on my 08 originally non-ZCP. If I do go the OEM route I'd pair with Dinan or Eibach springs to get a ZCP-like ride height (not any lower since there are already some challenging driveway entrances on my daily commute). If the ZCP shock is identical except with 1/2" shorter shaft then it could be ideal for my case. I had seen mention in the forum that ZCP EDC incorporated some additional sensors into the EDC control algorithm. But studying the parts diagrams I only see the same wheel sensors and same EDC control module with same p/n between ZCP and non-ZCP EDC cars. I'm still researching that one.

I might be one of the few that wouldn't be upset if I got a slightly elevated front with the Bilsteins. I have enough worry about scraping my front bumper and front CF splitters around here!
