Steel Alternative Brake Setup for Carbon Ceramic Equipped Cars?
Just picked up my "new to me" 2018 M5. It is equipped with the carbon ceramics which I have zero interest in tracking for obvious reasons.
Is there a steel rotor alternative disc that can be used for track days? On that same topic, if there is a steel rotor alternative available, does anyone make a track pad and titanium shims for this particular caliper? I have been unable to find out if this rotor and/or caliper setup is used in any other car (which would make it easier to get an answer to these questions). FWIW, I track my cars about 3-4 times per year. Thanks in advance! |

Now my new connundrum. My M5 CS is on the way with - Tah dah, only carbon ceramics. Dammit. FORTUNATELY, the ceramic rotors and the metal rotors are REAL close in diameter. Maybe 2mm radius off. I cannot advise this for certain right now, I haven't tried it myself. But it's REAL CLOSE. ONE thing I am certain of - if you can buy the blue calipers off a used F90 and rotors, you're in business with all metal brakes. They will fit for certain 1000%. The cost for this is pretty high - except the ENTIRE cost is less than ONE replacement brake rotor of the front carbon ceramics (probably why you're interested in this endeavor). So, take this under advisement. I know the problem can be addressed effectively. As far as track pads, best I have found is RacingBrake for this. Here go: https://racingbrake.com/f90-2018/ Pagid makes a metal "track" brake sold only in Europe. BMW will not export it here. One member found it for me in one of the threads. It looks prohibitively expensive ($700 plus for fronts). Supposedly, Endless is making a track pad in the MX line, but I cannot confirm parts numbers. EBC has some pads that fit the caliper. I cannot vouch for the pads, however. Good luck man. I have a track day scheduled for November for me. I'm hoping the CS gets here before that. I have procured carbon ceramic pads for the rear in preparation as backup. (BMW original). I have the same concerns you do. I hope they will stand up to the punishment. Shawn |

Oh yeah, this setup is also on the M8, if that helps.
My only beef is the shitty single piston rear caliper with the electronic parking brake. $100,000 car with grandma's 528i caliper in the rear. "Really, who throws a shoe?" Shawn |

You're welcome. BTW, replacing the rear pads is a giant PITA as well because of the electronic parking brakes. Supposedly, some OBD2 scanners/tools can retract the piston. I cannot find one. I use a mechanical retractor that winds the piston back in.
If you need help with this endeavor, I'll do my best. Shawn |

Getting the accessory tool costs about $25, and NONE of the above "fiddleness" is required. I can direct you to videos of both processes if you need. Shawn |
