I am looking at a pre-owned 2020 M8 convertible competition that has
carbon ceramic brakes. I am wondering if the maintenance and longevity of these brakes is an option that is an asset or something that will break the bank to maintain and possibly replace. My understanding is that carbon ceramic brakes show an increase in longevity as opposed to the standard brakes. The car I am looking at has around 15,000 miles. Another concern is that one of the options is the M Drivers package so there was a possibility the car was track driven, thus further putting accelerated wear on the brakes. Before purchase, I would have a pre purchase inspection done to check out the car. Any advise on this purschase and the Ceramic carbon brakes would new appreciated!

I've got them on my car and love them. Only 9k on it so far though.
I've heard they can last about 4 times as long as regular brakes. The braking performance is stellar. Best on any car I've ever owned or driven.
Plus almost zero dust. I've never noticed any but assume there must be some. My wheels are ceramic coated so it cleans off easier too.
They were a $10k option on my car new when ordered. But at this point I'd buy them again for sure. The performance alone is worth it to me. They are fabulous. I've never used the sport braking mode yet as they are pretty crazy good in the standard mode.
Enjoy those.
If it was track driven those would be the best brakes to have done that. They are built for the track. 15k is nothing. They should last to 100k I was told once. If driven fairly normal which I do.
The confidence they add is worth it to me. I know I can ALWAYS stop quicker than basically anyone around me in daily driving. A nice perk to have.

Love my ceramics.

The M drivers package increases the speed limiter and had a discounted driver school coupon. May or may not have been tracked.

We got such a good deal on our M8comp in late 2019 that we grabbed the car with steels. My only regret.
The car brakes very well but Carbon Ceramics are a no-brainer for the brake dust alone.

Absolutely love CCB's.
They will last 100k miles with normal driving but in the rare event they get damaged it will be a pricey event. You will find out that the $9k for the option is a subsidized price.

We had some manufacturing issues with 2 CCB front rotors on our E63s AMG. Some chunks would come out of the rotors. Each rotor is $4500 and the repair was $9500 with new pads for the front only.

Indeed - CCBs are fantastic until the replacement or repair cost has to be considered. For a leased vehicle, this is not a concern of course.

Best advice provided by my BMW Master Tech... be there in person when mounting new tires and removal or replacing the wheel assembly onto the car as an inadvertent wheel nick could damage the rotors... ($$$$).

Agreed, more likely that it was originally a GM ordering for a dealer and spec'd a car with all the options ticked. Normally I'd say it's silly to get it, it would have been a waste for my F80 M3 since that really struggled to hit the limiter, but looking back with the M8, I would go for it on such a high HP car, it bounces off the limiter with no real effort.

Anyway, I would only be concerned if there are signs it was a BMW owned/ driver school car, but I don't think they do that for any convertibles.

There aren't many of us from the forum that had our M8s at a track to begin with, maybe 3 coupes, 2 GCs, but 0 verts that I know of with me being one of the coupes. Many clubs blanketly ban convertibles for liability purposes. It's fairly easy to get an exception for an M car that was actually built for it, but it's enough to deter most that might casually think about it.

Are the current ceramics noisy at all during city driving? When I had them on the M6 a few years back they would make a high pitched noise until they were really warmed up with a few higher speed brakes. Since I live in the city it wasn't always easy to get those acceleration/stops out of the way until I hit the highway.

Only some sight squeal after a direct car wash. One or two stops and it's gone.
No noises other than that for me.

Right. Or make them use Lug Bolt guides. I use these when swapping wheels...

+1. The constant squeals on the steel brakes are much worse. I don't mind a squeal here and there on a performance car when I'm stopping... M5/8 steal brakes are known to squeal at low speeds while coasting, making it sound like you need pads to anyone that notices.

Any idea if the 19” winter wheel/tire package BMW sells will fit on my ceramic brakes? I have a 2020 M8 comp coupe.

[mpop302]

Silly question. I’m assuming these are the regular steel brakes not ceramic?

Correct

[mjr24]

Honestly, if they are $10-15k for replacement.....them lasting 100k miles is not enough. I've driven all my M's for like 2 years and put 40-45k miles on each of them. None of those cars ever needed brakes when turning them in for lease. Thus, in 100k miles maybe I would have changed brakes twice? That's still WAY LESS than $12k for ceramics.

Ceramics seem like more trouble than they are worth....for what, no squeals? 99.9% of us don't drive the car to where we would even notice the difference between steels and ceramics anyways.

I agree. Although I won't discount that CCB are a better performer for sure, plus they look cool lol.

I have OEM Steel and never heard any noises/squeels in any conditions from day one (original owner with 2500 miles). They were crazy super dusty. Almost a fine powder that had an adhesion factor built in just to fuck with us!

Anyway...I switched to ISO1500 ISweep Pads for about $800 for all 4 sets. If its no dust your looking for- these are the ticket. Cleanest brake pads I've ever had. I don't notice any stopping power loss either. -I'm sure there is a small amount though.

I would guess for most of us, that stopping "On a dime" isn't really a concern as the OEM system is pretty darn good. I would venture to guess that all-most none of us are using these cars to their full potential (as a daily driver anyways). I only know 1 person on here that literally falls outside this category and has his M8 for track purpose.

Also, it doesn't matter what brake system you have if your rubber cant hold up and grip and or the road conditions it self are not optimal. So there a lot that goes in to this making the wheel stop thing.

Again, I wish mine had come with CCB because then I would have them. But looking back now, for me, they wouldn't have mattered for my driving habits.

It will be interesting to see what the CCB package adds to the value down the road.

Hey mate, do you have a reference point for the 100,000 miles?

That’s alot of miles. I’m lucky if I will put 5,000 km per year

It’s all about brake fade, period.

[Ghostrider641]

Just did a run at over 160mph….CCB give you confidence the car will stop. Guess what, they work as advertised. I see these especially important as this car is 4300lbs and at speed you’re asking conventional brakes to work overtime…

Agree 100% But, lets look at some facts:
Carbon ceramic brakes are indeed better that steel brakes, but they don’t decrease stopping distance, as people commonly think. Instead, they reduce brake fade, which gives them a huge advantage at the race track — if you’re spending a lot of time on the track, your carbon ceramic brakes will basically never fade, even with many laps of hard driving. With steel brakes, you’ll feel brake fade fairly quickly.

So driving to the grocery store, or work, or a road trip - won't amount to much performance difference. (which most of us fall in to this category).

Here's what I see as the biggest problem with CCB. Around 100,000 miles, someone is going to need to change the rotors to the tune of $10,000 to $15,000. So my earlier point was a re-sale concern, now you have a 5,6,7 year old car that needs a $10-15K maintenance at best.

The thing is, while the carbon ceramic brakes may have made sense for the original owner, who spent $140,000 or more for the car when it was new, a 10-year-old AMG Mercedes is worth maybe $30,000 to $35,000 — and nobody in that realm is going to want to spend another $15,000 just to change the brakes. I seriously believe that this will dramatically impact the value of any AMG Mercedes (or BMW, or Porsche, or whatever) with carbon ceramic brakes once it’s more than seven or eight years old — much like how manual cars tend to become more valuable in the used market in part because they’re easier to fix if something breaks in the transmission.

Again, I'm not discounting CCB. I said "If they were on my car when I purchased it, I would have gladly paid for the option for the "cool factor" alone".

Yeah mate, agreed. I bought the car to track and if I didn’t need the CCBs for the track I would have kept the M850 and hopped it up. I got $17k more for the M850 in trade than expected during covid, so no brainer to order the M8.

Agree that it’s not a lesser car without them and looks expensive to replace, but I bet one could buy an steel Brembo kit at ditch the CCBs if they wanted to. And yes, who doesn’t just like to have everything on their car. To get the CCBs after the fact is just ludicrously expensive.
