The first two pages in this thread answered your question about the booster difference between CCB and iron rotors in the M3/4 -no need to change the brake booster if the 6/4 calipers and iron rotors are retrofitted to the M3/4.

Thanks for including an answer.

In my defense, there was a fair amount of conflicting information on those earlier post. CCB booster more powerful, no iron booster more powerful, no there's a servo shared with x, y, & z (v doesn't share) that can be adjusted. Friction this, friction that, it was because of weight or blah blah. Seemed to end without a consensus on this topic.

If someone with the iron rotors doesn't need to change the booster then does someone with ccb need to replace the booster if they went to the iron rotors? Or is this a coding issue?

Anyway, not having to replace the booster makes this a very attractive alternative over the ccb retrofit for me!

Two different boosters, one for CCB and another for iron rotors. Coding is for the ECU to know which rotors are in the car so particular booster works as designed with the DSC.

The OEM CCB retrofit includes the dedicated booster and requires coding. The logic is that the opposite must be true - having CCB and swapping to iron rotors requires the iron rotors booster and coding for proper function.

How much did you pay for these brake sets? Are they used or new?
Local bmw shop did the install. Got it done very quick. Only thing was the backing plates are quite different front and rear, so we just removed them. Shouldnít cause any issues. $5k for the full setup used with a few hundred miles. Install was a few hundred.

Anybody knows if the M2 competition calipers, the CCB calipers and the blue M5 6-pot calipers are all the same? Visually they look the same

I want to fit the M2 competition disks on CCB calipers, but there is a 2mm difference in width (steel rotors 2mm less width).

Front F8x M3/M4 CCB and F87 ZCP calipers are technically the same -color is the difference. F10 M5 calipers have ~6mm of material shaved off the mounting points of the brackets. In other words, to fit front M5 calipers in a F8x M3/M4 requires a bracket ~6mm taller than the OEM brackets used in the F8x CCB and F87 ZCP calipers.

The 2mm difference in rotor width is OEM negligible.

As above, but the measurement is 5mm.

Thanks. So this should be PnP. Have the normal brakes now and will change to CCB calipers and M2 comp. disks. Anything special to be careful for?

No not plug and play, as you would need the M5 caliper, M2 comp 400mm
Rotors, M2/M5 pads and then a radial mounted braket to suit the M5 caliper

But the M3/4 CCB calipers can be mounted without a different braket?

CCB and M2 ZCP calipers come with the brackets. PnP to any F8x.

Sorry for the confusion, thought I was replying to the guy who asked about M5 calipers...

For F8x CCB & F87 6 pots they come with the radial bracket mounted - so itís plug and play on F8x chassis with F87 M2 comp 400mm rotors.

For F10 M5 caliper, this caliper does not feature a radial bracket, so it would need a custom one making to suit the F8x hub and then could be used with the 400mm F87 rotor.

One guy did a DIY Retrofitt from normal steel caliper to CCB caliper and he told that there is a 2mm offset towards inside of the CCB caliper. So that means you need something to put in between the braket and the caliper to come 2 mm out.

He did it with a M5 rotor. But the diameter and thickness are same like of the M2 Comp except the hub diameter

The reason for the 2.5mm offset was because the M5 iron rotors do not have the same offset as the CCB rotors (and now the M2 ZCP rotors). For the caliper to be centered in the rotor, a 2.5mm shim was installed to the CCB brackets to move the calipers towards the inside of the car and center the rotor with the calipers.

That M5 rotors with CCB calipers mod is moot now with the M2 ZCP rotors in the market.
