I researched this for my E46 and there is a large disparity for long-term costs between different brands. I chose the UUC/wilwood kit because it uses relatively inexpensive OEM rotors. The data that I collected told me that pad costs are similar, the rotors make the biggest difference in cost.

For the StopTechs, PFC 01/97 pads will run about $750 and new rotors are about $1100 for all four corners, so estimate $1850 or so for a full job. I'm running the standard StopTech pads right now, but I'll probably switch to something else when these are done. I'll keep you posted on how the pads wear and how fast they eat the rotors.

I'm going to leave pricing questions to forum-supporting vendors that carry the line. Please check with EAS (European Auto Source), RennSpec, **********s and others. You may wish to call or PM their reps.
Sorry I can't be of more help. I'm here mainly for the tech side of things and the fact I've been a bit partial to M's since my first E28 M5, so not much else will do. I have an appreciation for many of the finer vehicles (the new Lotus Evora has me a little distracted these days), but only an M is an M! Chris |

Seals might need to be replaced from time to time, but that mostly depends on the temperatures they see. On the street, I would expect 8-10 years. On the track, well, that depends on temperature. You can apply temp strips to monitor max temps. Once 220°C / 425°F has been exceeded, a seal change is advised. Most track guys replace seals every spring as part of an annual maintenance program. Very few replace them more often. Chris |

A lot of guys were replacing their Brembo rotors with Stoptech parts when they needed to be replaced because it was much more affordable. I want to know if anyone is running the Stoptech Trophy kit yet?

I was told that some caliper designs might not incorporate abutment plates, and therefore if there were to be any significant wear, you'd have to replace the entire caliper body. Just wondering if that was true. Clearly, that is not the case for APR calipers then.

1 more thing I didn't think of. Since AP Racing works with OEM 18s, you'd have to consider the price difference between 18" and 19" tires as a cost factor. If you go with Brembos for example you are likely paying a premium for the required 19" tires vrs using the APRs and buying 18" tires.

Regarding the APs, don't they only work with the non runflat OEM 18" wheels. I believe the run flat wheels need a spacer. The spokes are a little different apparently.

The OP is running them with his 18" setup. Can't tell what kind of rims though.

Here is what one of the vendors said about OEM 18" fitment. It was from wheels STO. "We have been told by AP Engineers that the the AP Racing brakes were designed to fit on the OEM 18" wheels. However, they just learned that the same design 18" OEM wheel has 2 different specs. the 18" built for the run flat tires have different internal design compared to the non-run flat 18" wheels. The non-runflat wheels seem to clear the AP Racing bbk, but it is the runflat 18" OEM wheel that has spoke clearance issues. we are continuously getting updates from AP. Will provide more information as we find them out."

doba_s: Sorry - I was busy and missed your question!
I don't have any experience with the PF calipers and rotors. I've used their pads and they're great. As for wheel fitment, the OEM 19's fit fine all around. The OEM 18" rims come in two types - (North American Market Only) Style 219 that have room for the TPMS (not runflats - never runflats!) and (European Market Only) Style 260's that won't take the TPMS. The Style 260 rims clear the AP Racing front brakes without a spacer. Canada gets the Style 219's, the same as the USA (the good news is that we don't require TPMS). I have a garage full of 18x8.5" Style 219's and I use a 10mm spacer at the front with them. Tischer can supply the Style 260 rims on special order if you want them. I didn't think it was worth the aggro. |

By the way, while I'm thinking about it, the very complete BMW Motorsport parts catalogs that are now available for the E90 320Si WTCC car and the MZ4 race car both specify AP Racing brakes (with PFC pads in front) for these two pure-race vehicles.

I wonder if the catalogs spec the NA kits or the EU kits?

US and Canadian cars use style 219 wheels. Both will need spacer. It's style 260 that does not. Look back a few post and you will find more info about this from the OP.

By the way, going to a monoblock caliper would lessen the effectiveness of this brake system due to the reduced caliper stiffness. But at least it would cost more. Chris |
