CCB OEM calipers test retrofit in non-CCB M3/M4

Purpose: to find out what is required to fit CCB calipers in the standard steel-rotor brake system

Specs:

Iron rotors (standard):
- Front = 380mm x 30mm + 4-piston OEM Brembo calipers
- Rear = 370mm x 24mm + 2-piston OEM Brembo calipers

CCB brake kit (optional):
- Front = 400mm x 38mm + 6-piston OEM Brembo calipers
- Rear = 380mm x 28mm + 4-piston OEM Brembo calipers

Parts:

- 6- and 4-piston OEM Brembo calipers custom refinished in gloss metallic gold with painted-on racing Brembo logo and full clearcoat (from matte, non-metallic OEM gold paint) P/N 34117850463, P/N 34117850464, P/N 34217850465 and P/N 34217850466
- Front F10 M5 OEM steel rotors P/N 34112284101 and P/N 34112284102
- Front CCB rotor shield P/N 34112284767 and P/N 34112284768 (not shown)
- Centric Posi Quiet Semi-metallic front pads D1648-1
- Centric Posi Quiet Semi-mettalic rear pads D1155
- Front custom caliper bracket (not shown)
- Challenge Stainless Steel Brake Lines (not shown)

Front rotors

- First fitment problem
Right from the start, standard front steel rotors have a width difference of 8mm from the CCB rotors, which is unacceptable with the CCB calipers:


Solution - OEM F10 M5 steel rotors (400mm x 36mm):


-Second fitment problem
M5 rotors hub center diameter is smaller than M3/M4 hub diameter:
M3/M4 front hub diameter (~78.65mm)


M5 front hub diameter (~74.51mm)


M3/M4 rotor on top of M5 rotor


Solution - precision machined M5 front rotor center bore to 79mm with replica ~3mm chamfer (very important, just opening the bore to 79mm will not work, bore must have a ~3mm lip all around the edge of the bore)


Third fitment problem:

OEM brackets included with CCB calipers have a 2.5mm offset (towards the inside) difference when M5 rotors are fitted:


Solution - 2.5mm custom bracket fabricated and installed




Rear Rotors

- No fitment problems at all with OEM M3/M4 370mm rear rotor and rotor shield, 100% PnP:








Conclusion:
- Full retrofit requires minor custom front work but relatively straightforward if done by machine shop. Custom bracket fixed the negative offset of front CCB caliper with front M5 rotor. Front pads use counterweights to eliminate any vibration. Front pads are also available without counterweights. Centric pads were selected for street use (low dust, better than OEM performance). Porterfield street and racing pads are available.

Rear fitment was 100% PnP. Rear pads were selected to cover most of the gap between the pad contact area and the rotor. The rear pads that can be used for this Brembo 4-piston calipers is a 67mm D1155 pad.
Thread will be updated with performance review once fully installed.

Looks nice but is there any difference in moving to this setup?

Difference should be the same as getting an aftermarket BBK but with OEM parts and at about half the price.

Prototype bracket used with an OEM F10 M5 front caliper (OEM front calipers do not include the OEM bracket as in the F8x M3/4):

There is a kit (OEM CCB calipers + aftermarket rotors) made by Endless that include 400mm and 380mm rotors (not OEM).

Review:

It did not take long to realize that the braking power of this 6/4-piston + bigger front rotors retrofit is something else compared to the standard M3 4/2 piston setup. Brake feel, stopping power and overall pedal response is significantly improved. Brake modulation is still nicely balanced but with a more solid feel with less pedal pressure. After two months of use no noises, no vibrations, nothing negative to report. I used to have a full Brembo BBK in my old E92 M3 and it never felt as much as an improvement over the OEM brake setup as this retrofit. Really happy with this effort.

Note: this retrofit is using the same standard OEM brake booster for iron rotors with no coding changes as the standard 4/2-piston iron setup. No need to code/replace the booster for CCB calipers as in the OEM CCB retrofit kit as the coding is to adjust the CCB booster to the friction of the CCB rotors, which is different from the friction of the iron rotors. So no no need to code/replace the standard brake booster for iron rotors for these calipers.

Thats awesome glad it worked out well for you. Is there any way to find out if the rear CCB caliper will fit on the stock rotors of an F86 X6M? It seemed like in your post the only issue you had was mounting the fronts with some custom work but how about the back? I want to use the stock rotors on my X6M with the rear caliper of the CCB but no one has done this from what Ive seen on the forums other then you. This is the part number for the rear rotors if it can help with my question. 34212284904

Thanks in advance!

You will need to do your own homework as your rear brakes use an electronic parking brake (don't know if the X6M rear calipers are part of that system; no F8x has electronic parking brake), and definitely you need to measure the rear OEM caliper brackets in your M as they are going to be completely different from the M3 rear caliper brackets. You may need different brake pads as well...

What kind of Brake pads else i can use? Im from germany and it is quiet difficult to get the Centric brake pads.

You write that the centric Pads are better than the OEM Performance Pads. Which Performance Pads i can use for this caliper? Of the BMW F10 M5?

Any pads with these backing plate shapes:

Front pads D1648-1
Rear pads D1155

For example, Hawk HPS in D1648-1 for F10 M5 iron rotors, which is the same front pad for the front CCB calipers. The D1155 rear pads are for Ferrari and Corvette rear Brembo calipers. Check with your brake pad manufacturer about these shapes.
