OEM Rotors
So I did something dumb.
I will be doing a few track days this summer. In preparation for it I got PFC pads and motul RBF 660 fluids. This past Friday I took my car to a buddy's shop to change out the pads and fluid as the oem fluid were due for service (service light came on) and I knew oem pads were below 50% thickness. Unfortunately I forgot one small but important detail... oem rotor thickness. My buddy measured it and the fronts were at 28.7mm. The minimum being at 28.4mm, I was told the stock rotors won't survive the summer with a few track days thrown in there. I knew my rotors weren't perfect and was only hoping to make it through this year with them. Now... should I just get oem rotors since I have brand new pads (less than 30km driven on them) in there. OR bite the bullet and get BBK and sell the PFC pads? Yes yes, I know I don't neeeeed BBK now but I' planned on getting them some day and I will be doing more track days down in the future.

People send their oil back in and they replace it.

If going OEM FCP for sure.
Don't forget you will pay to ship the old ones back and you maybe rotorless for a tad.

I'd say rock them until they warp, being below min thickness doesn't mean they will disintergrate, just be ready to replace them at first sign of warping or sign of fatigue. Last edited by tdott; 03-17-2019 at 01:45 PM.. |

I was going to say the exact same thing
PFC DD rotors up front, match them with your rear stock rotors. It is more braking power than you need and the DD rotor keeps much cooler than stock |

Unfortunately being in Canada, PFC rotors and oem rears will still cost me about $2000 by the time it gets to my door. At that price I might as well spend it on a BBK, or no? |

Pfc dd v3 rotors are like 1.2k usd with a set of pfc pads. Stoptech front calipers and rotors go for 2-2.5k usd used with questionable pads and rotors which may need replacing At those price I'd buy the dd with my eyes closed. Good luck going through a single set of those rotors. You already have a set of pfc pads. Hopefully the 11s. So if you buy a front bbk you'll have to sell those |

Anyways been searching here and there throughout the day and I’m leaning more towards bbk. Yes yes I know it is an overkill but it is something that I plan on getting down the road, like in 2 years time. So decision decision... spend $1.7k Pfc dd front and oem rear now and call it a day... or bite the bullet, $4.7k stoptech st60 front and st40 rear (quote from a vendor). I still have a couple of months to make up my mind. I don’t need to do anything till June. PS... the karbonius groupbuy isn’t helping in this situation... but totally worth it!

Apparently they don't care, even if you are replacing them on a track car - they'll still honour the warranty. That's pretty incredible, good on them (for us at least haha).

One of my M3s has the PFC bbk up front only and the other has F+R. Using the same pads in both I cannot discern a difference other than the speed at which I go through consumables -- the rear BBK pads/rotors last forever and ever. Although the rear oem caliper pad and oem rotor also last a while |

The key here is to get a piece of wood and hold the brake pedal all the way down before starting. This 'locks' the brake system and doesn't allow it to drain. Do this first, then take your time while its held down and when done you just have to bleed the fronts. Bleeding ABS with INPA/whatever is a good idea because the pump cycling improves brake feel as the fluid in there can get old. |

Man when I did the bbk (stoptech) install on my other car many years ago it was a lot simpler with little to no computer controlled functions. |

Computer stuff is a pain, however, before you had no way to do the abs bleed and now you do... so it has its advantages Let me know if you run into trouble, i have done a few of these |

For the dust shield, should I remove it or trim it? Seems like it is better to remove it completely as it offers better cooling to the brakes, but will that introduce more dust in the wheel well area?
