So far so good. About brake dust, I've not seen any from these. I have the BMW styling 405 Performance wheels which have both anthracite and silver color and I haven't had the silver part dirty from brake dust.

That's good to hear. I just may end up pulling the trigger on those. Thanks for the update.

Alex is it difficult to install the new ECS Lines?

Sorry but I'm not capable of replying to that question, I didn't do the job, it was done on a brake specialist shop.

I'm still within the 1,000 kilometers of "breaking in" so I've not yet tested them at their fullest, but first impressions are:

- Way better bite
- Pedal feel on semi hard braking more firm
- Noisy, by that I don't mean squeaky, the slotted part makes a "windy" noise, more so when you hit the brakes.

I will come back when I pass the 1K kms and go do a track day where I will have the chance to push them to their limits.

Here are some pics, of before and after installation. Gotta be honest, I love how the look on my car.

EDIT: looks like uploading pictures from the bimmerpost app on iOS does not work. Here are the pics.
I had the exact same Performance Brake Package installed by my dealer prior to delivery of my M235i (even the same color). In addition to the differences mentioned of the rotor diameters and weight savings, these brakes also have a different compound more suited for high performance (track) driving. I love them, but would have preferred that the rotors were actually drilled rather than just dimpled. This has me wondering if the OEM rotors from the M2, which are actually drilled, would fit these calipers? I had a 135i that I put the Performance rotors on and the fronts were actually drilled while the rears were dimpled like these.

Drilled rotors are more susceptible to cracking than dimpled rotors.

M2 380mm front rotors won't fit, even though the calipers are the same. m2/3/4 mounts on to hub carrier are different to accommodate 380mm rotor.

Slotted, drilled or dimpled rotors are mostly for the show, a wow factor.
As far as function is concerned plain rotors usually provide better braking than slotted and especially dimpled or drilled. Drilled rotors are more prone to crack. More noise, too.

Yep agree 100%

Before - stock



After - MPBBK



Fitted MPBBK with M4 sport pads, steel hoses and DOT5.1 BF and the stopping power is better for longer in terms of fade resistance etc

An often repeated idea that has been around so long and repeated by so many (including engineers in the industry who should know better), that it is accepted as unassailable fact. There has been lots of testing (I mean real empirical engineering tests, not "Golly gee on Billy Joe Bob's super stock at Daytona in 1985..."). Most of the really good engineering data, some of it conflicting, remains proprietary. Here is the only (that I know of) published engineering test data on understanding the mechanisms by which corssdrilling affected brake performance:
http://papers.sae.org/2006-01-0691/
Not the most definitive study on the subject, but at least there's some data in there to argue about. Oh, and the correct answer is, it's complicated. Cross drilling may decrease or increase brake performance depending on the brake design and intended vehicle use.

There seems to be a lot of confusion going on regarding the available braking systems for our cars.

This happens because the "2NH M Sport Brakes" option when ordering the car means different braking systems on different cars and markets.

Do not mix up "337 M Sport Package" with "2NH M Sport Brakes".


System 1: M Sport with 340mm front

Front:
-> 340x30 one-piece plain front discs (PN 34116792223, same as standard 335i)
-> blue fixed 4-piston calipers (PN 34116799465)
Rear:
-> 345x24 one-piece plain rear discs (PN 34206797605)
-> blue fixed 2-piston calipers (PN 34216799461)

Fitted on:
F20 EUR: all vehicles equipped with "2NH M Sport Brakes" and as standard on M135i/M140i/M235i/M240i
F20 USA: as standard on M235i/M240i
F30 EUR: all 14i-20i vehicles equipped with "2NH M Sport Brakes"
F30 USA: newest 28i/30i vehicles equipped with "2NH M Sport Brakes"


System 2: M Sport with 370mm front

Front:
-> 370x30 one-piece plain front discs (PN 34106797606)
-> blue fixed 4 piston calipers (PN 34116799469)
Rear:
-> 345x24 one piece plain rear discs (PN 34206797607, seems to be the same as system 1)
-> blue fixed 2 piston calipers (PN 34216799461)

Fitted on:
F20 worldwide: not available
F30 EUR: all 28i-40i vehicles equipped with "2NH M Sport Brakes"
F30 USA: newest 28i/30i vehicles equipped with "2NH M Sport Brakes"


System 3: M Performance with 370mm front

Front:
-> 370x30 one-piece slotted and drilled front discs
-> yellow, orange or red fixed 4 piston calipers
Rear:
-> 345x24 one piece slotted and drilled rear discs
-> yellow, orange or red fixed 2 piston calipers

Worldwide: only available as accessory

Front and rear discs are the same as system 2 (same weight as well), except for the fact that they are slotted and drilled.
Front and rear calipers are same as system 2 (same weight as well), except for the color.


F8x Braking System

The M2/M3/M4 (without ceramics) use the same calipers as system 2, however, they use bigger and much lighter two-piece drilled discs. (380x30 at the front and 370x24 at the rear).

They are able to use a bigger disk with the same caliper because they use a different carrier - the distance between the middle of the axle to the mounting point for the calipers is bigger. These disks are not plug and play in a standard F20/F30 car.


Final words

OP sees a significant difference between his old factory M Sport to his new M Performance brakes because he had the small discs.
Some people see no difference when upgrading to M Performance because their cars had the big discs to begin with.

i just asked my local BMW dealer about the MPBBK and to replace the rear protection plates you need to remove the wheel bearing and in ding so damges it and is not reusable.

can any one chime in on replaing the rear protection plates with this kit - did you do it , did you need new hubs/bearings?

if the rear discs and calipers are the same, why replace the protection plates then?

I was just going to say that. You are correct. There is no practical reason to try to change that plate on an m235i/240i car. I can confirm they are identical. Skip that and don't worry about the wheel bearing.
