I want more braking power... I do not care about the weight. One extra person in the car has more impact.

The blue brakes are shit at high speed on the Autobahn and on track, the track pads are a hell when you daily and without a money tree in my backyard I will never fit CCB's.

The new brake kit is the best combination for what I need... If I would have kept my M2, I would have fitted a Brembo BBK and I would have the same issue of increased weight. Only positive thing is that I now factory warranty.

Exactly. I'd end up replacing ccb rotors with iron rotors anyways. The exact way the 2NH brakes come.

I optimized your first post + added a couple of additional pictures.

I don't care that new brake are not shit!
Have you tried blue brake on the track and ccb?? After that you will understand how different is ccb from iron brake! Believe me
2000 dollars for new iron brake is a waste of money. For sure

Have you tried a good set of proper brakes with iron rotors, like a Stoptech Trophy kit. Not comparing any kits, but quit trying to spew this CCB bs. If you want CCB rotors, buy them. They will mount right up with the 2NH package. The blue standard brakes are sh*t, I agree. I guarantee the new brakes are far better, with increased rotor size/thickness, more rotor service and increased in piston count/size. They will provide improved thermals, shorten stopping distance and last longer than the standard sh*t brakes. You want some one-off CCB for M2c for $7k option, f*ck that.

Where did you find the weights for the 2NH rotors?

Why do you think it's must have? If you've run a current M2 with upgraded track pads and fluid was there ever a situation where you felt the current brakes weren't up to the job? If so can you please explain with data why they weren't up to snuff like rotor temps etc?

I've run the "standard" brakes with RBF600 and DTC70's on Slicks/Hoosiers in 130F+ track temps lap after lap at intense braking tracks like COTA with no issues (mid 600 to mid 700 rotor temps) with no fade.

I'd love to not have 35 pounds of extra unsprung weight for no reason, not to mention the extra weight from the 19" wheels and tires you'll be forced to run.

I am aware of that, but I don't track my BMW as much as my MINI. The M2C is a daily and since I am on mountain passes and autobahns more than on tracks I do not care about the weight.

For the little cost of the upgraded set, they are a no-braining for me. Especially in the way I use them. I don't need CCB's, and never will on a M2C. Not with how I use my car.

This is a well discussed topic on various Porsche forums. Ceramics are great for the reduced brake dust and weight benefits, but replacement cost are a huge negative, especially if using the car for track days or if one gets damaged!

I’m sure I also read on the GT3 stopping distances are no different between a car with Steel or PCCB, what you do get with PCCB is better consistency due to less brake fade. This can be mitigated with different pads and providing better cooling.

One thing I will say is that the M4 standard steel brakes are great and these being substantially larger will only make them better in terms of stopping power and durability due to better heat dissipation.

News flash if you think oem street pads that come in the new upgraded brakes will be fine for track duty you're in for a surprise.

The front brakes are straight off the F10 M5. F10 M5 standard front caliper is the same as CCB front caliper on the M4. F10 M5 front rotor is a 400x36mm.

13.870 kg
http://www.realoem.com/bmw/enUS/part...&q=34112284101

The rear brake rotor I used the 380x30mm rotor from the front standard brakes of M4/M2.

11.300 kg
http://www.realoem.com/bmw/enUS/part...&q=34112284809


Using some educated guesses on where they are getting the parts from. They certainly aren't sourcing all new rotors. Even if they did, they each would be within 1kg or less of what I have listed. 30lbs increase at the minimum, but I think 35lbs is right on the money.

Mperf will have a more aggressive pad option available for track use.

I just did the front and figured out the total area of just the brake rotor without the hat. Then calculated the volume for that vs stock brake and got 15kg. My way isn't 100% accurate either, but if you split the difference, yes you're withing 1kg. Think that's as close as we're going to get until the official tech specs are released.

Yeah, the parts should be up on realoem or etk at some point.

Ciao, the biggest problem of "blue brakes" are not the iron rotors, but the bad stock pads. Put good pads, brake hoses and a better brake oil and you'll solve all your problems and you won't need anything more, saving a lot of money compared to CCB with which get forged wheels to reduce unsuspended masses, for example
About CCB, don't forget the bad cold response, bad modulation in city driving and the high costs of spare pads and rotors. For me, CCB are total waste money

For street use once you change pad, blue brakes are fine, in my opinion and my m2 is no limited with 7me. With this brake I already had to leave the pedal to avoid back car jump into mine .
I drove m2 ( not mine for sure ) in Monza. Misano, Imola and Mugello and if you want to full enjoy the car ccb are mandatory...!
I am totally sure that Bmw will make carbon disk retrofit kit for new brake otherwise is no sense increase power to the cars.
My disappointing is for tons of carbon upgrade, roof tail, side mirrors and so on but no carbon on the brake, that for sure will be cheaper way to increase performance and weight!
We will see

It is amusing to see people nitpick every single detail. BMW is offering an oem big brake kit and people are still complaining. Amazing really?! How can someone's reality be either 4/2 piston system or ccb, I WANT NOTHING ELSE IN BETWEEN? Earth shattering news, larger calipers and rotors weigh more. Yes, people actually put big brake kits on cars. There might even be a huge big brake kit market out there, with majors brands involved(could be imagining that). I was just trying to show were some of the new weight could be coming from. The vast majority is coming from performance upgrades, whether is be brakes, engine, cooling, etc.

Do these new 2NH silver sport brakes / red M Performance brakes come stock with the 'normal' brake pads or do these come with those noisy race pads ?

The question is... is stopping capability of the car actually improved...? or is this just keeping up with the extra 150 lbs..



hopefully there are actual improvements to be gained... There seems to be a reason that they are an included " upgrade" in many markets..

Very possibly because they are needed... or.. very possibly so they don't have to print a spec sheet for M2 COMP with a 0-60 stopping distance that is worse than the OG M2..

thanks for helping define the weight gain in the car... it appears 120 lbs is due to the motor and associated cooling.. .. and another 30 lbs is due to brakes if the 2NH kit is included on the US car as it is in Canada. As stated above... just because BMW is adding these changes.. doesn't mean the absolute performance of the M2 competition will be greatly changed vs the OG M2.

Indeed.. I surely hope that the changes will result in measurable changes in performance, it will be interesting to see instrumented reviews.

On the f15 the brake set upgrade is not so expensive, what will be the cost of this option??
