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.

They continue to be pure perfection.

On the stroker E90 we have the full PFC BBK. It is hard to describe to which point they satisfy, completely. There has not been a single moment where I wished for anything else.

When we bought the F80 CS my brother and I were so certain we wanted to use the PFC Z54 front caliper that we spent months measuring, drawing up in Solidworks and getting brackets 3d printed before committing to an aluminum bracket.
You see, PFC does not build a bracket to adapt their BBK onto the F80, so we did it ourselves. It took a massive amount of time but we managed to do it.
That is how good the BBK is.

For the rear position of the CS we were concerned about parking brake compatibility so we went with the 'other' high level kit: AP RadiCal.
The RadiCal looks very cool but the rotors are a large step down vs the PFCs.

If we end up buying a G80 in a couple years we will take whatever time is needed to move the PFC brakes there.


Over in the stroker thread there's a video of a track day. It does a 30 min session and then it goes out in the next run group for another 30 min, all day nonstop.
In the AER cars we run full PFC brakes as well.

PFC has no forum presence and terrible marketing but they are certainly the real deal. I don't think something better exists.
Thanks for sharing your experience. Curious why you view the AP rotors as a step down from PFC?

just spoke to Bimmerworld

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

Two main points:

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'm happy AP exists and they have great support. I really like that there's another true top tier kit for us track people for the E9X, as the rest are not up to par. It's also comforting to know AP will probably release brackets to adapt their kit to the G80 within a month or so of the car coming out.

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.

The Z54 kit fits under the stock 18" with a 12 or 15mm spacer. Both the Z54 and the Ap RadiCal use 372mm rotors
