Yea the Z45 rear kit with the V2 rotor sans belleville washers is noisy. The Z54 front with V3 doesn't seem to be as noisy.The retention ring setup seems to reduce motion/noise?

Interesting. I have the PFC Z54/Z45 and Z31/Z31 e9x M3 brake setups. I have no rattle and/or free-play noise issues with either setup. The Z31 F and R rotors both use the V2 mounting method and no belleville washers (not sure how they’d help anyway because the twelve bolts are hard mounted to the outer hat flange and inner rotor shear tab support ring?).

Also worth noting that I have no rear seat, rear carpet, and rear trunk floor insulation. So I get a lot more sound from back there.

The Z54 is pretty quiet for what it is |

To my knowledge we don't have any confirmed evidence that the pad tension blocks cause any type of taper issue (or any other issue) when run on the track under typical conditions. There are a whole bunch of potential reasons for pad taper, and taper is actually very normal. Have you ever read our Essex Racing Pad Owners Guide ? I address the topic of taper in that article. Please check that out if you haven't...lots of practical tips that could help you squeeze more life out of your pads. Here's a dumb question for you...are you positive your calipers are on the correct sides of the car? We've had about 3-4 instances over the past couple years in which the owner or their shop installed the calipers on the wrong side of the car and they saw considerable taper. It happens more than one would expect! As others have noted, with our pad tension kit installed, NVH isn't going to be much different than a stock car in most cases (assuming you have a pad like the DS2500 in the hole). For those who want a more OEM-like experience, we have our AP Racing by Essex Road Kits. These will still handle the heat of the occasional track session in lovely fashion. |

With the pad tension kit installed NVH was at the level I expected from a top level BBK, which is definitely not quiet like stock but easily livable. I noticed you guys took out the more street oriented line, good idea as that is what most people need |

On your car, the piston at the top of the caliper (towards the sky) should be the smaller one, and the piston on the bottom should be larger. Thanks! |

Unfortunately that's how they were installed. The small piston is in the top on both sides of the car

For 95% street / 5% track, anyone runs stock disc, slightly aggressive pads, stainless lines and like motul/castrol/ate fluid?

Stainless lines = better pedal feel is a myth in these cars. What happens when you change lines? New fluid. What is the number one contributor to spongy pedal feel? Old fluid.
If your oem lines are old and need to be replaced anyways, stainless can make sense. |

Brass caliper pin guides will clean up any vague pedal feel 100x more than ss lines will, but if you dd the car and don't like going into your brakes monthly to clean and lube those pins that might not be a good idea.

I have been running brass caliper guide pins for several years and do not need to clean them and lube them monthly. More like every 10k miles of street use.

That's awesome to hear. I just got mine a few months ago. I've read you should take care of them often since there's no dust boots and tight tolerances, so I just wipe them down and lube them up when I'm swapping pads from street to track, and back. Sounds like if you've got a street only set up, you don't really need to worry about a maintenance schedule as often as I'm messing with my brakes.

so cant reuse the oem plastic caps for where the guide pins were?
For 95% street / 5% track, anyone runs stock disc, slightly aggressive pads, stainless lines and like motul/castrol/ate fluid? So for this, any recommendation for pads? Stoptech? Hawks? brake fluid, ate type 200 or motul 5.1?

Stock discs are fine for a light track use, if you know it's only ever going to be an occasional thing. Again, lines are a total waste of money performance wise unless your current ones are in dire need of replacing. Oem lines are steel lined, they DONT expand. SS lines are a safety measure in wheel to wheel racing where debris on the track could cut your line. Pads: everyone told me to run ferado DS2500's for my first day couple days. I did. Didn't have any issues and am able to run them on the street with maybe only the lightest of squeaks every few times out. Now I run ds.uno in the front on track day, and will likely move to ds.uno in the year before my next track day as well because confidence is up and lap times are down. |

i feel like this thread is calling me out originally i had grand plans to track my car at least a couple times a year and i had read on the forum that the stock brakes were the "weak link" and needed to be upgraded if one wants to track the m3 so i got ST60 for the front, left the rear alone i only made it to 1 track day so far swapped in track pads, brakes were great but i think i would have been fine with the stock brakes and the ST60 is definitely overkill for me so i spent good money on a nice red BBK to make the car look better

Nothing wrong with having a front BBK and make the car look better, I probably won't track my M3 but tempted to get a front only BBK for it at some point (although those FCP Euro lifetime rotors are tempting)
