You can see a range of pads on Dave Zeckhausen's website. Make note of his useful comment at the top on rear pad factory shim design.

Looking to paint a set of BBK’s in this color, but many reputable M vendors didn’t have the color code. Thanks!!

Shuggy,

You receive a response on this? I am interested as well.

Thanks
Hey, sorry for the late response.

Unfortunately, no. Though I believe the closest shade is Limerock Grey, but it's not 100%.

As an alternative, I wanted Polar Blue to match reupholstering and stitching I've been doing in that thread. However, while it's a thread color, they didn't have it in paint, so I went with a blended Atlantis Blue Metallic.

Contrast on Space Grey is actually quite good.

Yes and No

Yes - as far as geometrically/size/mass all same grey/red/gold.

No - gold ccb calipers have high temp internals to suit elevated ccb operating temps ie titanium pistons and better seals/dust boots. CCB pads are slightly different - compound to suit ccb and shape with large surface area

Ok, so if i put ccb caliper with iron brakes discs would be better than M Performance with iron brakes?

Notionally yes but difference would be marginal unless your car is being used for lengthy TD's / endurance events with lots of high speed / heavy braking

M2 Competition 2NH brakes feature the F8x carbon ceramic brake’s calipers (F&R) with 400mm/380mm steel rotors. And the F10 M5 standard brake’s front calipers are the same as F8x CCB front calipers.

Standard M2/M2C brakes (blue) (source: see here):
  • blue front caliper - 4.890 kg or 10.78 lbs
  • blue rear Caliper - 3.600 kg or 7.94 lbs
  • 380x30mm front rotor - 11.300 kg or 24.91 lbs
  • 370x24mm rear rotor - 9.300 kg or 20.50 lbs
    = 58.180 kg or 128.26 lbs
2NH M Sport Brakes (silver) - M Performance Parts Brakes (red):
  • silver/red front caliper - 7.540 kg or 16.62 lbs
  • silver/red rear Caliper - 4.310 kg or 9.50 lbs
  • 400x36mm front rotor - 13.870 kg or 30.58
  • 380x30mm rear rotor - 11.300 kg or 24.91
    = 74.040 kg or 163.23 lbs
Extra weight of the optimized silver/red brakes compared to the standard blue M2/M2C brakes = 15.86 kg or 34.97 lbs
Came to realize that the M2C big brake rear rotor weight are over quoted here. They should read 9.5kg/21.0lb, for a total weight difference of 12.5kg / 27.5lb.

Is that not because it's missing most of the fixings?

I have issue after brake changing.

So my car is stage 2 tuning. And i asked bmw dealer to change M performance brake(red brake). the dealer said the tuning file is gonna be lost and the car will be standard file after coding the brake pressure. And after it all was done, my car has drivetrain notification. the dealer said, i need to coding the tuning file. But after i coding the tuning file, the car still have drivetrain. So i took bimmerlink it shows 2 error code.

1. D90D37 interoir light unit, incorrect variant install
2. 1f2108 DME, incorrect data record: variant monitoring

my tuner said i need to ask the dealer for fixing the error code but the dealer said he afraid that i need to pay extra cost if the bmw offer to change some engine car’s components which i don’t have much knowledge about the engine of n55. My car has not anything broken before changing the brake.

I need some advice. What should i do now?��

I've been getting the interior light error code since my car was new. I can clear the code but it just comes back. AFAIK it doesn't hurt anything.

DME incorrect data error code happens when there is a flash tune. I don't think it causes any effect. The only way to get rid of it from my experience is to flash back to stock.

If you are talking about a light on the dash drivetrain malfunction, I don't think it would be necessarily connected to the error codes because they are very common.

Brake changes have no need for DME mapping. The BMW dealer is talking BS.

Put your stage 2 map back on. Obviously warranty is not an issue for you so tell BMW to get lost.

Who is your tuner? That's bad service.

Did you put the stage 2 back on?

I'm still not clear, how does the drivetrain error show up? Is it only when you scan for error codes or is the car indicating somewhere on the dash that there's a problem.

To get rid of the data error with the ECU, it may need to be relocked. Relocking (BM3) and clearing all error codes is always a good idea before going in for a service. Of course if the car is bench unlocked relocking isn't an option. The interior light error code will not go away even if it's cleared in my experience. The data error must be cleared after flashing stock tune. It won't go away by itself. I've seen it cleared with Carly.

You really need ISTA for diagnostics.

Agree you have to "clear" the faults, they don;t just go away by themselves.

Is there a "drivetrain fault" dash indication? Limp mode CEL etc?

I asked for advice from another garage service. they said if the Ecu box is not lock for flashing to stock, they can fix it. If its locked, they said i need to buy new ecu box and they will install the original stock tuning file. it cost around 2000$ 😭

Do i need to buy a license of Relocking (bm3)?
Do you to the bootmod3 right? My car didn’t use bm3 for tuning. my tuner use ecutek.

the drivetrain is show up on the dash screen here

If your car was built before March 2019 it can be locked and unlocked at will through the OBDII port. If it was built before July 2020 it can be bench unlocked. The only ones that need a new (old) ECU are cars built after July 2020.

There could be something else wrong with your car having nothing to do with the tune.
