What's the weight compared to 19 including tires? Bc 20" tires will be a bit lighter.

Either way the zcp tires still have decent sidewall. The sidewalls are taller than 225-245/35/19 tires that are extremely common on other cars.

The combined package (wheels and tires) for the 20's is heavier as well. The weights were posted several months ago.

Yea I figured that just was wondering the numbers. The tires are wider than the non zcp package so that adds a pound each even at 19".

Thanks

FWIW from tire rack:

19" tires:
265/40/19: 25 lb (star BMW)
285/35/19: 28 lb (26 lb if they are the 275 star BMWs)

20" (star BMW):
265/30/20: 24 lb
285/30/20: 26 lb

So you save 1 lb F, and 0 or 2 lb rear on the tires depending on which tires come on the 19" ZCP pack. So it might narrow the gap a bit.

But your comparision isn't including the correct 19" OEM tires, which are 255/35/19, 275/35/19.

Don't the zcp 19s come with 265/285??

If not that's pretty terrible and reason enough to get the 20s

Comparing OEM setup to OEM setup for complete 4 wheel/tire combis:
18" 513M 184.7lb
19" 437M 192.4lb
20" 666M 213.6lb (CP version)

So the 437M add 7.7lb over the 513M and the 666M add 21.2lb over the 437M and 28.9lb over the 513M.

As I have posted previously, the weights of the 666M are rather disappointing considering the were marketed as "weight optimized". On the other hand, the 513M and 437M are not that bad for OEM wheels in terms of weight. I am eager to read the specs of the new 19"-20" staggered M-Performance wheels, they are supposed to be the lightest design yet.

Weight is not the only factor. It is how the weight is distributed. "Weight Optimized" could mean that there is less weight at the edge of the wheel, more at the center.

I think we are splitting hairs here.

For me, the greatest impact of wheel weight is unsprung mass. Rotating mass is less important. How the weight is distributed around the wheel does affect it's impact on unsprung weight.

Great info. 20 lb is insane. Too bad really. I love the wheels they look awesome but I kinda wish they just looked the same and were 19" instead (I mean GTS fronts are 19 wth) and had the 265/285 tires in 19 instead.

Oh well. Prob gonna get track wheels anyway.

from the photos I've seen of the 666M wheels of that Sakhir Orange M4 ZCP, seems like BMW is stocking Michelin Pilot Super Sports again

I don't think the CP was ever offered with anything else than the PSS...

The 18" and 19" could come with the Conti, but IIRC, not the 20".

That's good to know. My 2017 M4 Convertible came with Continental P5s

No more luck of the draw now with the CP

PS: Are you going to upgrade to the LCI 2018 like I did or you're sticking with your current M4?

Yes, it has always been my plan to change my 2015 M4 this year for a 2018MY. I am anxiously waiting for the specs of the rumored M4CS, if the price and package is right, that's what I'll get. Otherwise I will settle for a CP LCI M4.

This is what I ordered, production will start in late April:

Ordered a BMW M4 F83 ZCP YMB 2018! (specs inside)

its annoying that people guess. i didnt guess tho, it was what i was told by BMW Seattle. but thanks for guessing that i was guessing...

but you are saying the 19s are 10.5 inches wide in the back like the CP 20s?

Just had a flat in Portland last week and no they do not stock that tire. Had to wait 5 days and rent a car while i waited for that damn tire to come in.

The 437m 19s are the same width as the comp 666m 20s.

"- 9x19 (ET29) +10x19 (ET40), Style 437M"
http://f80.bimmerpost.com/forums/sho...d.php?t=945713

And from the first page of this thread
"Forged, machine-polished, weight-and rigidity-optimized, multi-spoke 20-inch M alloy wheels (front 9J ×20; rear10 J ×20)"


I believe they even have the same offsets. So the only difference is wider tires, and of course more weight on the 20s.

While you are correct that the part number is the same, this topic has been discussed extensively elsewhere. According the the BMW engineer I spoke to during the factory tour in Munich, there were internal changes made that improved the sound. The part numbers stayed the same because it is still an exact fit for either a 2015 or a 2016 (or probably the standard 2017). My 2016 sounds completely different than my neighbor's 2015, which bears out his statements.

Having said this, it still kind of sucks, and I'd take an MPE or a ZCP exhaust any day of the week!
