Granted BW is the largest retailer of PFC kits, but wouldn't it be better to get that information from PFC? I just spoke to their tech support 2 weeks ago to find out what the wear limits are on their rotors.
They're in my state, maybe I'll call them next week to find out what's up. |

The only thing getting disco'd is the E36 kit from the stone age and even then, you will still be able to get pads/rotors/rebuilds/etc from PFC and Bimmerworld So we're still good |

No 'v3' style mounting. So the rotor is mounted to the hat using little bolts/nuts/spacers which take quite a while to swap. Use that, then swap a rotor that uses the 'v3' architecture like the PFC Z54 kit and it's night and day. For the V3 I need a screwdriver and maybe 10 minutes. For the regular rotor style... you'd better have a chair. The casting. The AP rotor uses a rough casting on the outer and inner surfaces of the vanes. The PFC has machined surfaces. We'll see about durability as well. I have pretty good data in terms of pad consumption, taper wear and rotor wear for the PFC, I'm looking forward to seeing how AP handles itself. So far only 1 set of pads on the AP but the taper wear was significant. Will give the kit the benefit of the doubt and see what happens with the second set of pads. |

I agree that the V3 mounting style is slick. However, that isn't something that I put much weight on considering rotor replacement is relatively infrequent. Durability, price and performance (plus weight) are far more important to me. You are in a unique position to directly compare those aspects. I'll be curious to see your long term findings. PFC definitely has the race pedigree and the fact that Porsche is using them on their cup cars is a huge testimony. I would argue that AP Racing has even more race pedigree and certainly more history given they have been around for a longer time frame. I would gladly run PFC on my car. My only gripe is the fact that they don't provide caliper diagrams (hard to check wheel fitment without that).

I shot an email to bimmerworld about getting a diagram and unfortunately the dont have anything for the Z54 set up but they also followed up with this:
"Unfortunately we do not have a template available for the Z54 PFC caliper. We do however, have a template for the ZR54. It is essentially the same caliper but just with a lower offset rotor. You could print that one and mock it up with the thought that the caliper is actually going to be 18mm more inset. Please let me know if you would like me to send those your way. What wheels are you running? Thank you!" I'm sure someone can figure out if the Z54 set up will work based on this diagram and a good knowledge of wheel offsets and other relevant data. |

30,000 Mile Update
I've had my brake kit on my E90 M3 for just over 31,000 miles since 2017 when I installed it (documented in this thread). Has been absolutely trouble free for both track and street. Just this past weekend I replaced my rotors for the first time. Couple of observations. Though wear limit of the rotors is 30.00 mm and I was at 30.5 on the fronts, in the last 2-3,000 miles both sides have developed 2-3 grooves per side and then the rotor surface has developed a real shiny, almost polished look . No deep cracks, just the usual heat checking all over. The other thing is that though the V3 spring retention system is nice, if your car is a daily like mine and drives in all weather (well mostly rain is as bad as it gets here) is that the spring retainer will corrode and then the leaves will stick to each other. Makes it much more of a bear to remove than when new and all the parts are smooth and shiny. It's probably a "replace every other rotor swap item" if you daily drive in all weather. Only requires some light sanding with 400 grit paper and I put a really light coat of grease on both sides and reinstalled. Otherwise it's not really a biggie. I put on a new set of street pads as well as so it's all a new matched set, will have new track pads for first event in 2020 as well. No regrets, it's a really nice system and super reliable. |

beautiful brakes....should have picked it up when it was FS earlier a few weeks back. Oh well, guess I have to settle for StopTech Trophy for now

I have a couple of questions for those in the know about "the PFC king of kits":
1) What is the PFC kit new rotor ring thickness? 2) What is the Brinnel Hardness rating of the PFC rotor ring? Please, only family friendly responses to #2. Thanks.

No idea on the hardness of the PFC rotor ring Edit: the Alcon/BW kit uses a 36mm front rotor which is quite insane

Once you have been using PFC aftermarket components for a while you'll understand why they are superior to most all of the other offerings.
My M3 is gone now and I'll be switching to a Mustang (I know BOO!) but I've had such good luck with PFC that though I can't get a BBK for the Mustang, I have located the V3 rotors. The stupid thing is, they are manufactured literally 100 miles from me, but since availability of these is nonexistent in the US, I had to order a set from the UK. Should be here next week, go figure, the rotors have to make two trips across the Atlantic to get to me. But, it's the first mod going on the car. |
