I own both a 2015 M3 and 2017 M3 ZCP - Feel free to ask me comparison questions

It is still hard to comprehend how a car with stiffer spring rates, stiffer anti-roll bars and lower profile tires can have a smoother ride.

The black 20's are sharp (IMO)! I tried to get the dealer to switch out the silver for black, but it was a no go. They didn't have any.

I have the black 19's on the '15. I'm sure as more people take delivery of their CP 2018's we'll start to see some posted in the forums for sale or trade.

I agree, lol.

So maybe the difference is the programming. :

Is there anyone who has driven the non ZCP with 19's and the ZCP with 19's?

Like I said, I didn't read the 100's of pages about the differences between ZCP and standard. So I didn't have a built in bias of what was "better" (besides the small HP bump). On a bumpy road I have much more confidence in the CP to keep me in control of the vehicle.

Programming of the EDC is also the first thing that came to my mind. But maybe there is also a change with the linearity of the spring rate.

Agreed. Just wondering if you felt the value was there having had a chance to own both. I've been hard on the ZCP but might add the option on the next ride when my lease is up. The black Satan's are starting to grow on me and I want the "better" exhaust.

I've not yet driven a CP but I hear this same exact thing from people who don't seem like dipshits. so congratulations, btw.

What I'm trying to figure out is, are the "CP is a way harsher ride" people full of scat or is there some configuration that is ...

People who don't have the CP will always find something to make them feel like they don't want it.

It's in no way harsher, I've had both, it's the same freakin' ride in terms of harshness or comfort but a little improved in power and exhaust note. End of story

Not once did I feel like "OMG this is such a harsher ride", in fact, you feel more in control with more connection with the steering wheel and the road. It's also more predictable thanks to the linear power curve rather then giving you that sudden splurge of power before being almost dead...

When I saw the black 666 Ms in pictures, I liked them, just for the sake of standing out...but when I saw them in person....they blew my mind away....they have this 3D Illusion effect that give the car a lot of character....

Also something no one mentioned before....if you look at the car from the back.... the tires look really wide giving the car that beastly super car look

Here's mine...

BMW never said the ZCP got stiffer spring rates, just different. In all likelyhood they went a tad softer, or just valved the shocks better and went with a stiffer sway bar in back.

However, I would argue defining ourselves solely by our past ignores a significant part of reality: the present and the future. That said, a denial of our past constitutes an inauthentic lifestyle.

Sartre called it facticity, and defined it both as a limitation and a condition of freedom. It is a limitation in that a large part of one's facticity consists of things one couldn't have chosen (like your parents) and a condition of freedom in the sense that one's values most likely depend on it.

Moving tangentially to absurdity, I think your point is that the only meaning of the CP is the meaning we give it, and while it may be an option we choose, that free choice is - and must be - derivative of our histories.

wow, I feel like I finally understand why BMW offers the CP.

Haha, well played. Now ifnI could just remember which movie that was from.

I had almost 20k miles in my M3 and now 8k in my ZCP M4. Honestly man I can hardly tell a harshness difference. I had the stock 20s for a good time and now aftermarket 20s.

I think there is a tad more road noise with the comp pack but im not sure its due to the tires as I had 19s on my car for a few weeks and it seemed the same. Maybe its the M4 has more than my M3 had who knows.

You have nothing to worry about. I run sport suspension 85% of the time, sport + on twisties, comfort on harsh roads in F83 ZCP. The whole ZCP setup is noticeably better than than non-ZCP.

[Aaaaaaaaa]

The ride comfort issue is probably software calibration. I had a '04 Volvo S60R and it was Volvos first attempt at electronic damping control. It had big meaty 17" tires and it rode like $hiiiiiiiit. Newer models were better but no matter what mode I was in, the ride was harsh, jittery, uncontrolled over bumps. I actually pulled the fuse that controlled the system and it rode a lot better. Main reason why I went with standard suspension on my 435. But sounds like BMW got it right with ZCP.

Eibach measured the spring rates, the CP springs do have higher rates than the standard ones. They also increased the rear-to-front axle rate ratio with the CP springs.

Good to know.

If you see that in a movie, tell me which one so I can get my fucking money

sigh... another thread that makes we want to get a ZCP before the individual content ends in Jan. OP, do you have an MPE on your '15? How about your ZCP? I'm on the fence if I want to add an MPE or if the ZCP is good enough. From what I can see in the comparison videos, I'm leaning towards the MPE. Combine that with the ZCP and that's $10k in options already!

Not sure about the OP but I have the ZCP with MPE. After my huge disappointment with the stock exhaust on the non ZCP M4 4 months back, when ordering the 2018 M4, I didn't even wanna take any chances and have to wait...I went MPE straight away and man....it sounds insane....the loudness of the MPE coupled with the burbles and crackles of the ZCP is the best of both worlds...

That's odd, seems like catless dp's and replacing secondary cats with resonators on the zcp exhaust has a nice note to it.

I don't know about the technicalities.... all I did was order the MPE with the car and the dealer fitted it after cutting some part of the old exhaust which is according to BMW instructions.... but what I do know is it sounds nothing like the stock exhaust, it's a whole different level of loudness and joy..... louder than even some V8s that I've heard

Yes, I have MPE on the '17, stock exhaust on the '15. The MPE sounds better, even with the valves unplugged. I do not know what MPE sounds like compared to the "stock" CP exhaust.

I'm sure the MPE will pack out and sound better once the miles start to build up. Hopefully I don't get the no cost "cracked muffler" mod
