ZCP Suspension Parts(Retrofit) on Non ZCP Car

I have tried to search but not sure this has been answered:

The difference between the EDC ZCP suspension and the EDC Non ZCP Suspension parts are the springs, shocks and the anti roll bars.

Has anyone taken a non ZCP car's suspension with EDC and added the OEM ZCP parts for the competition retrofit and do you need to recode the car?

I have seen some post that have just added the ZCP anti roll bars.

Worth the cost to upgrade the springs,shocks and anti roll bars?

Thanks.

I wanted to do something similar... I don't believe it's possible to retrofit the shocks/springs.

If u want EDC you must get a car that has EDC.

The other parts should work.

I retrofit the swaybars and coded the suspension EDC with the competition setting.
I didn’t change the spring because I don’t want to have the car any lower.
What I know for sure is that the swaybars and the spring are different between the competition and the standard, not quite sure about the EDC shocks.
The swaybar are a nice upgrade, but unless you go on track I doubt you will feel any difference.
Coding the EDC is an easy mod and you can feel the improvement right away
Hope it helps

Changing to CP spring will not lower the car. CP cars have the same ride height as the non-CP cars.

I am going to be the guinea pig here. I have the sway bars installed already and plan to install the ZCP struts in the next 30 days. I will post back my results.

Reason for not getting zcp springs?

Thanks and let us know the cost including install?

Yep, a car with Electronic Damper Control(EDC) adaptive suspension and a non competition package.

When I ordered the car, the comp package was not offered at the time or I would have check the box on that option.


Thanks

Not swapping to ZCP springs because I already have the m-performance spring kit.

Frankly, I am not sure I want to go through the effort of swapping struts and springs after having car corner balanced but will probably go through with it anyway since I have all the parts.

ZCP dampers have been installed on my non-zcp car for two weeks combined with M Performance springs and ZCP coding for the EDC. There are definitely valving differences between the ZCP and non-ZCP dampers and something I was not expecting is that the shaft is about 5mm shorter on the ZCP front struts. Overall rebound damping on the ZCP struts is MUCH better than non-zcp and the car recovers from big bumps and settles much better but there is a tradeoff in that compression damping is firmer so the ride is rougher.

Do I like them? Yes.
Do I think the change is worth it? Probably not if you daily drive the car, the compression firmness makes the car less comfortable in everyday use. If this is a weekend/track car than yes.

My favorite setup for daily driving has been non-ZCP dampers, ZCP EDC coding, M Performance springs and ZCP sway bars.

I will come back and add more color here as I put more miles on the ZCP dampers

Great info!

Do you know the differences between the non-zcp and zcp swaybars? Diameters, lever lengths, etc.

I did measure the sway bars before installation but it's not easy to document as they are not a consistent diameter. I will add pictures if I can find something that explains this.

Great and appreciate the info.
Interesting regarding the front shocks are 5mm lower, so you have less of a wheel gap.
Let us know on your experience and thoughts with more miles.
Right now, their are only a few options regarding EDC shocks until Bilstein comes out with their EDC shocks for the USA.

To clarify, car is no lower but shaft is shorter to account for full suspension travel with lowering springs.

I wanted to bump this and ask a follow-up question: Is it possible to do this retrofit on a 3-bolt non-ZCP F8X EDC with a HAS kit? The 3-bolts have a different pn for struts but not sure if that actually matters if you are only swapping the strut itself.

Don't know which three bolts you're talking about, but I can confirm that it doesn't matter if you're only swapping the struts/shocks themselves.

The struts and shocks are exactly the same on the outside. I swapped mine to ZCP, and the only way to tell them apart was by the part numbers on the stickers. Therefore the HAS kit should not be affected in any way by swapping struts.

The ZCP struts will work fine with the early 3 bolt mounts. I have that setup on my car including MPHAS; I went with the full CS suspension on my 2015. Highly recommended, by the way.

Thanks!! My installer confirmed as well.

I'm pretty much doing the same setup as you except with KW HAS so I am glad to hear your feedback

*edit--almost the same setup after reading your threads... how crucial is the ZCP rear sway bar upgrade in your opinion? My goal isn't really track-oriented (I'll be lucky to get 2 sessions, realistically just aiming for 1), just general refreshing of the 2015 setup.
