There are a couple aftermarket companies that make replacement iron rotors for M3/M4 CCB owners.

For reference G30 Mperf BBK, which are only a 4/1 piston setup...are $3370 msrp.

Exactly, not going to be inexpensive.

Here is an example of what the G30 Mperf BBK consist off.

1. The iron rotor ccb replacement kit from Racing Brake

2. The front and rear discs that are for the M2C BBK that are due for release August time so Im told.

Looks like ~$800 hundred more than a set of OEM rotors, not too bad I suppose: https://www.turnermotorsport.com/e/B...e-rotors-discs

Interested to see what BMW's prices will be... hopefully somewhere in-between stock and aftermarket BBK rotors? If so, that could be quite enticing.

So caliper, disc, and pads I could probably sell for $3,500?? I hope, it will offset my bbk...

One thing that does not seem to get considered here, is that when you get an upgraded BBK from factory, they "get to keep" the stock brakes. In other words, the buyer is only paying for the upgrade. If you buy it aftermarket, then you can factor in how much you can sell your stock kit for, if there is demand for it.

Very nice, that is the way to go for a dedicated track car.

It won't really matter what brakes you put on the M2 if there is poor airflow to them. Something the 370Z community is very familiar with.


For a track toy, why not consider a C7 Grand Sport? Tires may be more expensive but has huge availability of brakes and wheels. Much faster car and it's lighter.

I'm not sure about these brakes on the M3/M4. I think there are a lot of variables, driver, track, temperature etc. I would think for many the standard brakes with pads, fluids and SS lines would work just fine. I'm all for bigger brakes, but the BBK offered on the M2C seems crazy heavy.
In the meanwhile I had a track day at Laguna Seca and there was on M2 in my group. The guy was dealing with brake fade big time, but he had stock pads. From personal experience, that is not going to work on BMW's. Might get away with it on a Porsche, which come generally with bigger brakes on lighter cars.

Yes, the GS Vette is pretty capable. Coincidentally a buddy of mine got one recently and was at the track with it. He does not generally track this car, so it was completely stock, yet he was on par with me, and I have all the track mods under the sun. So with similar mods (mainly tires and brake pads) the Vette would be way quicker, and would be a great step up from an e46 M3.
However, I just don't see myself EVER in a Vette. Sorry, but that car is tainted with "midlife crisis, old man image". Not to mention it is nowhere near as practical as a M2. (can't haul a set of track wheels in it)

F10M MCCB Gold MN6 - Titanium Pistons, additional 5mm Caliper Mounting Surface Length.

F8X MCCB Gold MN6- Same as above with Axial Mount Caliper Adapter Bracket

F87 M2C Grey/Red MN6 -Same Caliper Housing and bracket as F8x MCCB, but with Stainless Pistons.

I attached a pic of the 5mm difference in surface mounting length between the F10M Blue Brembo MN6 and F10 MCCB Gold Brembo MN6.

Is the F10 MCCB Gold Brembo MN6 the only caliper in your list that has a 5mm longer mounting depth? So the F10M Blue Brembo MN6 caliper, F8X MCCB Gold MN6 caliper (without bracket) and F87 M2C Grey/Red MN6 caliper (without bracket) all have the same mounting surface length?

My dealer gave me some prices of the calipers and disks (in red below):

Bimmerworld has front calipers listed at msrp $1,317 /each. No other parts listed.

The Gold, Red, and Grey MN6 are all the same housing with the additional 5mm. F10M Blue MN6 is the oddball.

So, the brake pad fitment is not going to be the same as F10M blue brakes then? Seems like a new fitment because it's for housings that have only been used with CCB before?

Same front pads as F10M Iron.

I try ccb on the m4 in Monza circuit compared with iron brake and the difference is enormous.

This new brake are just add of weight, lost of tire size (18 inch) and no more than half lap of durability.

Talking of road use will be worst for noise and more fuel consumption.

Basically a waste of money. A real upgrade was if they develope with Brembo a small ccb system, lighter and with 18inch rims

You got the point right on.

Ah, interesting ... I thought the F10M Gold was the oddball due to larger rotors, but what you say makes sense now. Thanks.

The 'unmodified' calipers:
F10M Gold - radial mount over 410mm rotor
F8X Gold with bracket - axial mount over 400mm rotor
F87 M2C Grey/Red with bracket - axial mount over 400mm rotor

'Oddball':
F10M Blue machined down 5mm - radial mount over 400mm rotor

So gold F8x front caliper can be used on M2 Competition by changing to M2 Competition 400mm iron disc & M2 competition pads?

I have a set of F8x gold CCB fronts with no pads & discs.

I want to try & fit the 6 pot fronts onto a F31 with M2 comp 400mm discs, using a custom axial mount.!

[R99]

Anyone seen part no’s for the pads yet?

[VIERsr]

From EVO review:

brakes wilt under pressure

From BMWblog review:

The upgrade brake system is impressive as well, possibly saving my butt in a few late braking situations, so despite the additional weight, it’s a worthy upgrade.
