Alternative to PFC11 for Stock Calipers?
I love my PFC 11s but they're generating way too much heat and after 5-6 laps I start losing around ~1s from my fastest lap.
I know the best bet here is to get a BBK but I don't want to spend that kind of money right now. Some brake cooling would help too but all of the rigs I've seen so far isn't something I'd go for so I just want to know if there's a pad that generates a little less heat and holds up better throughout the day. |

What's wrong with a DIY cooling solution in lieu of a full-on BBK setup? I planned on designing my own in Catia but decided to go with the quick and dirty route others in the forum have already done. It definitely reduced temps at the front/rear brakes > improved pad life. It still won't be nearly as good as a BBK but it's better than nothing at all. Replying to your comment in the other thread. I've never lost the brake pedal with any fluid/pad combination; however I have experienced serious, almost wreck inducing, ice mode with Pagids and the PFC08s. |

Oh no. I do not recommend even trying the 08s. Seriously, go with Ferodo/Gloc/Carb/Hawk upfront.

Give them a shot and report back in this thread or with a pm. My suspicion is that you will have even more issues with the 08s. I didn't like the initial bite at all, and the pad was quickly overwhelmed with threshold braking. |

Just remember the 08 is the endurance pad which was replaced by the 12 compound, the 11 is the race pad that replaced the 01 pad. So besides Gen X vs Gen X+1 there's also the endurance vs race difference
I don't think it's possible to overheat the actual pad in the 11 compound. I know because I've tried very, very hard. I suppose your brake system is failing somewhere else |

I’d look at the rotors. The F8x OEM iron rotors aren’t efficient at pumping air thru the cooling vanes due to the aluminum hat-pin design. The F8x design is a huge improvement over the E9x design but it still reduces air flow. Last edited by M3SQRD; 10-02-2019 at 10:31 AM.. |

I'm doing my best to avoid investment in a BBK, so I know my weakness roots in brake cooling. The fluid boils quickly so my pedal gets soft as well but typically they wait until the end of the day to reach those temps. Prior to the fluid giving out, I do notice I lose consistently in brake distance with the 11 as I approach the latter part of my sessions. I discussed with PFC and aside from both of us agreeing that the stock brake system is a sham, they did say that 08 will be much more consistent throughout the session/day. They didn't say it was going to be a cure for my woes, which I'm already certain they won't be but they did say it should help me keep my confidence throughout the day and that it was worth a shot. I'll be debuting them at the Glen so I'll follow-up. |

Are you using SRF? My e9x is a heavy pig, on stock rotors with PFC-11 it isn't fading after 5-6 laps. Pedal went a little soft at Palmer but it was 100F+ and the brakes werent really cooling at all. I'd like more confidence in the brakes in general, but I think that's the rotors / calipers not the pads. I'll be at WGI this weekend as well with NASA

I'll never forget the number of useless tools on this forum that swore the brakes were wonderful and they were God's gift to man... what a way to perpetuate a lie. The stock brakes are wonderful for all the hard parkers who are like 'yo man 380mm rotors!'. |

The 2:04 was the E90. The E92 doesn't go to the track anymore but back in the day it did 2:09.1 with RE71 tires and MCS suspension. On the CS no improvements vs the first weekend we drove the car there, where we did 2:06.7 with RE71 tires and stock suspension. It has MCS suspension now but we are dialing it in and it's proving go be very different than the E90 for whatever reason. So currently it's not any faster than it was stock but that will change. |

I loved the PFC08's for my e90 but when I started using them with my F80 and did not like them. I moved to Ferodo D1.11 and I like them much better. I feel that they have better initial bite and more consistent through the entire braking zone. They wear better and will never go back to the PFC's again
