The R4 pads seem to be deisgned for the track, but not much feedback out there on the 135i ... The PFC 08 pads are true "endurance" track pads, with all the pro's and con's of such a pad. Lot's of feedback out there on other cars. PFC just started producing them for the 135i, and http://speed-freaks.net/ is the first vendor to sell them ...

Thanks for reply dcaron! Yes , the R4S are for street and wasnt meant for a track pad comparison , just as an excellent street pad. The R4's and raybestos are used in tribute to lemans endurance races on tracks like Willow springs. 911's use them a lot , but wasnt sure if they felt equally as good on the 135i.
Thanks! Dan |

I should be getting a set of PFC 08 pads within a couple of weeks. I have two other track days planned for September at the beautiful Tremblant track over here in Quebec.
I have had excellent results with my Project Mu Club Racer pads with no brake fade to speak of at high speed tracks. Will see if the Performance Friction 08 pads are as good, and I will report back .

I will be looking forward to your review. I wanted to get the Pads however due to the delay I had to get another set of Carbotech XP12s to finish off the track year. If your review is positive for next track season I will switch to the PFCs.

Look at what just arrived at my door! Will be installing these PFC 08 brake pads soon, and trying them out on the track and street. Will post a review afterwards.
A few pictures. Probably the wrong and preliminary packaging for the 08 pads:

I replaced the Project Mu Club Racer pads which with the new PFC08 pads.
Also did a brake fluid bleed while I was at it. The pad layer thickness on the new PFC08 pads is almost the same as the Project Mu CR pads with 7 track days and 2 months of street use My front calipers have turned golden from all the heat resulting from one year of abuse at the track. The caliper piston dust boots are also toast. I will probably replace the boots, pistons, and rubber brake lines this winter.

You should consider adding brake ducting. It makes a huge difference and not just for preventing fade but extending rotor and pad life. BTW did you run titanium shims? If so I guess it didn't help with the dust boots? |

Ill have to reserve final judgement on the PFC08 pads until Ive spent some more track time and street use. Regarding cooling: Beyond the stock bumper air dams, I have been running 0.5mm Ti shields and F30 cooling shields (see pictures in my last post) for almost a year. I still generate a lot of heat as you can see by the white residue on my pistons and charring on the TI shields. Heat is probably building up more since Im getting faster, and using wider wheels in the front (8.5" versus stock 7.5"). I might consider brake ducting next season (Spring 2015), and also may give cooling hub attachments a try. I cannot find the link to them, but they cover the wheel hub and provide an inlet port to connect tubing to.

These look nice and surely costly ...
http://www.m3post.com/forums/showthread.php?t=800855 There are these for the E9X, and Ive sent an email to Cantrel Motorsports to inquire about fitment for the 1 series. http://www.cantrellmotorsport.com/in...art&Itemid=117

I did a write-up for my car few months ago here, obviously the DIY will not apply exactly but I do have links for hardware that you should be able to use (hoses, clamps, etc). Also, you should shoot a PM to CJ421. He's a member on e90post that I see often at the track. He has a very clean LCI 335i and installed brake ducts but it's very OEM clean looking and I bet you could emulate a lot of what he did. I think he was able to integrate his hoses into the OEM trim... Dallasboosted also installed ducts here but I like CJ's install better. |

You maybe better off riveting 2.5" flanges onto your backing plate, and running 2.5" hoses. Here's the write-up that inspired me to tackle the job: http://robrobinette.com/S2000BrakeDucts.htm The key is to get the ducting closest to center of rotor as possible. Directing it outside towards the face of the rotor won't do you much good. The air has to get inside the hub area. |

Do you think 2" tubing would provide sufficient airflow to be of use?
Looking at website you provided in your ZPost build thread I came across a 2" flange that I think would be ideal to match up to our oem brake cooling ducts: see here. I've sent an email asking the dimensions of the backing plates. According the Q&A section, the OD is 2", ID approx 1 3/4". So potentially way too tiny. The idea is worthwhile though, choose a flange large enough and weld a square plate to it that would rivet to the wheel liner and transition from square bumper duct to round tubing. Another simpler, but no doubt less effective, option i was considering was a Porsche GT3 brake duct spoiler see here and attaching them to the M3 control arms. Not sure if upper or lower arms would be best. Granted these would not be directing airflow to the most effective location (centre of hub), but in combination with F30 shields could prove useful. |

My car is slightly lowered and i am running negative 3.8 camber up front with 3mm spacers, front fenders rolled and flared, i still cant fit anything bigger than 245/35 without rubbing everywere. But i am using r-compound tires that run wider in the same size. Might try street tires now, getting tired swapping them at the track every time. |

Put on new rotors, new PFC08 pads, and bled with Motul 600 fluid before a track day on Summit Main. I also finished some 2" brake ducts to the fronts. Overall, I'm very pleased with the PFC08 pads. I bedded the pads in on the street before the track day - they were extremely squeaky before bedding. Just did about five 60-10MPH brakes and they started working well.
At the track it took several laps before they started to feel consistent, but after that, they worked nicely the rest of the weekend. Not quite as grabby as the DTC60s or 70s but very very close. These will be the pads that I use going forward. They do click when going from reverse to forward, but it's not a big deal. Not sure if they don't sit in the caliper as tightly, or if there is something else. Gotta have a nice clean rotor! Pads after: -Joe Last edited by joeo; 09-19-2014 at 06:00 PM.. |

Did you notice how thin the pad layer is compared to others pads? I hope they last as long or longer than other pads. In addition to my Ti shields, I used backing plates from my OEM pads with the PFC 08's because I got tired of the clicking sound and occasional rattle over sharp bumps. I like them so far both on the track & street, and they are surprisingly quiet on the street, with a rare squeak at very low speed stops. such as when parking the car. Way quieter than Carbotech XP10's ... On the track, it took a few sessions to get rid of brake fade, but once they settled in and had a few heat cycles in them, they are now much better.
