F30 M Performance Brake Retrofit - Initial Impressions
So I've had my M Performance Brakes for about two weeks... here's my experience so far:
I'm planning to sign up for the BMW CCA autocross school in San Jose next month, so I'll have another update by then. |

Looks great. I want these so bad but since I have 17s for winter wheels, I would have to spend another 1500-2000 to change them out as well.
For the install, I think they pushed your car aside for others. There is no way this install should take more than 3-4 hours tops. It is a direct bolt-on/swap. I've witnessed it. Either they broke something taking it apart or putting it back together where a part had to be ordered or they broke a bolt or something that required them to drill out and tap but even that would not take a long time. Those estimates by BMW are way over inflated to do jobs which is why independents can typically do the job cheaper. |

Just installed M Performance rotors too!
I use my car in track too and often on mountain roads, so I often need all brake power. I confirm your bad feeling with pedal response, but I know it is possible to change it by coding and that's what I'll ask to my dealer

You may want to check whether the dealer has added/coded the "SPBR" in your FA (VO).
Since I had a similar mushy-pedal experience when I first installed the M-Performance Brake. I did the VO-Coding of the DSC module and then FDL Coding the correct disc size for the front/rear rotor. With correct coding. The pedal feel should be very similar to the OEM and also a little bit firmer. No more mushiness |

Yes, you need to have the OBD cable and hook it up with your laptop, and use E-Sys to look under the FA (VO) folder.
Or you can find someone who know E-Sys coding to check it for you. http://f30.bimmerpost.com/forums/sho...d.php?t=929406 This is what I did. In the DSC CAFD, look for the following folders to update the rotor size to F: 370mm and R: 345mm C_Variante_Bremsscheibe_vorne_e change to--> 370mm C_Variante_Bremsscheibe_hinten_e change to --> 345mm Then FDL code this values into the DSC. My friend's M135i came straight from BMW AG and equipped with the blue M-sport brake. When I looked at his FA, and found the SPBR was not coded at all so I coded it for him. He could feel the difference immediately. Since then he has no more complaints about the mushy brake pedal. I suggest you to take a look at the FA first.

That's encouraging! My service advisor is out for the week so I'm waiting until next week to figure out if this was coded or not. I'll report back here.

That is who I go to but I have not built up the confidence yet in their sa but the mechanics I do. I am a little concerned that they could not do this job right the first time given their volume of customers.

Just have back my car today, alter coding M Performance brake: now they are set on "Sport" and the feeling has improved: now I'm happy of the brake pedal response! Very satisfied about brake power and bite!
