2016 F82 ZCP Wheel Spacers

[petite_baguette]

I ordered my F82 ZCP w/ CCB at the end of Feburary with a mid-June delivery.

I'd like to install some spacers for a more aggressive look but I can't find any reference for the 20" wheels.

To give the full context, I will also adjust the ride height using the new, hopefully available before June, M Performance Coilovers. If no MPCs by June, I'll look at substituting with a set of K.W. HAS.

I would appreciate any insight on this configuration.

Many thanks !

The 20" CP 666M wheels have the same width and offset as the 18" and 19" wheels. So you should be able to use those as a reference.

Thank you !

Considering the OEM wheels with a .8" drop, it looks like 15/12 are a popular configuration. What do you think about this ?

I've got 12.5mm spacers on the back of my F80 right now. They push out the wheels 0.50" on both sides for a total of 1" wider track. With that said, I'm planning on putting the 12.5mm on the rear of my ZCP F80 when it arrives this summer.

Hope that helps.

Excellent. What do you plan to do for the front ?

Did you do a wheel alignment after installation ?

No wheel alignment needed after adding spacers. You are only removing the wheels and nothing else. Alignment remains the same.

Considering the CP wheels are just slightly wider than the OEM 19's, I'm going to wait and test fit the 12.5'mm in the rear to see what they look like first.

But, chances are I'll probably end up picking up 10mm spacers for the rear and putting the 12.5mm spacers up front. I like my wheels perfectly flush or just slightly inside the fenders.

I share your wheel positioning preference. So it looks like you may end up with a 12.5/10 configuration considering the wider CP tyres.

Exactly. I think my M3 CP should be arriving around the same time as yours. Keep me posted on what you decide to do. I'll share my results as well.

Sure. I'll continue to research. Perhaps it will be possible to see some ZCP examples before our arrivals from those who have already received their car. Cheers.

I hope so. Although from the sounds of it, most people are hating the CP wheels and would prefer the OEM 19's over the 20's.

Btw, what color did you order?

I don't think it matters too much the rim choice because IMO the lower 20" aspect ratio, 30 vs. 35 for the 19", means the overall wheel diameter should be very similar so the wider tire width should mostly drive what spacer sizes look best.

I decided on Azurite Black / Amaro Brown. I was torn between Tanzanite Blue.

Sorry, I should have clarified. The preference on wheels was in regards to the aesthetics. Seems like most people agree that the 19's are a much better looking wheel over the 20's.

Great color choice! Azurite is one of the favorites.

I agree. However, I like the 666M's. For me they offer the right sophistication and subtlety. In France, it's not so common to showcase.

I'm excited to see the actual car, I think the colour and wheels will present better than the photo renderings.

As I posted in post #2, the 20" 666M CP wheels are the same 9"/10" front/rear width as the 18" 513M and 19" 437M wheels.

Only the GTS 666M wheels are wider by 0.5" front and rear.

Thanks buddy!

What I meant was tire size. Sorry for the confusion. I was thinking that a smaller (10mm) spacer in the back would help compensate for the slightly (negligibly) wider foot print of the 285 rear tires while a 12.5mm may be ideal for the front.

Just don't want anything poking out.

Thoughts?

My understanding is a wheel is an assembly of rim and tyre.

While the ZCP 666M 20" rims are the same width as the 437M 19" rims, the tyres do not have the same section width at 265/30/10.7"(SW) vs. 255/35/10.2"(SW) Front and 285/30/11.4"(SW) vs. 275/35/10.9"(SW) Rear for ZCP vs. base F8x respectively.

While your definition above of a "wheel" can be technically correct, your definition of the "rim" is not. The "rim" is only the outer portion of a wheel that holds the tire and is connected to the hub by the spokes to the wheel hub.

The term "wheel" is most often (almost always) used to designate the rim-spoke-hub assembly without the tire.

And yes, the CP does have wider tires.

That's a good question and probably depends on personal preference.

I tried my 12mm spacers with my 295/35R19 PSS mounted on the 427M wheel and found it poked out too much. I settled with 5mm spacers in the rear because that is what I had at hand, but I think 7~8mm would be ideal with the 295 section width. Note that the 295/35R19 PSS has a significantly wider tread than the OE 275/35R19 (by a whopping 1.6" or 41mm). In the end, choosing the right spacer will depend how much wider the tread of the 285/30R20 is relative to the 275/35R19. But your guess of 10mm spacer is probably in the right ballpark.

...And Bob is your Uncle. Many thanks for the lesson in semantics

My point was simply to draw the distinction between the components of a wheel in relation to my inquiry about the best spacer size I could use.

Not sure why you are riding your high horse, you're the one who started it by correcting me regarding the definition of a "wheel". For the vast majority of folks here, the understanding is that the wheel excludes the tire.

The reason I brought precision to the point of the wheel width, is that for most, when choosing spacers, it is the position of the wheel face that matters for the sought after "flush" look, not the tire; and wheel width has an effect on wheel face position. I thought it would be pertinent to point out, that contrary to the E9X and E46, the F8X CP does not come with wider wheels. What makes it even more confusing is that the 666M wheels of the GTS are wider. I have read quite a few folks confused about that point.

Further, a numerically wider tire will not necessarily change the "flush" look. It is all about tread width, not section width. A tire's installed section width is highly dependent on the width of the wheel it is installed on. So a 285 tire will not be much wider than a 275 tire when mounted on a 10" wide wheel. What matters is tread width, which varies very little with wheel width. The relationship between tread width and numerical section width varies greatly from tire to tire, even from one PSS to another. For istance, the section width of the 295 PSS mounted on the my 10" 437M rear wheels is barely wider than the OE 275, but the tread width is a whopping 40mm wider.

I've ordered 12 (front) and 10 (rear). Had my measuring stick out (on another CP) and reckon should be fine. Will be putting onto coilovers most likely anyway so didn't want anything daft.

Car arrives end of this week so will soon find out!

Excellent. I was thinking 10mm front and 5mm rear considering the best utility and look. I also expect to install a set of MP Coilovers.

I will be eager to see your pictures with the 12/10 setup. Cheers.
