Aftermarket brake rotors
Just ordered a set of Akebono Euro ceramic brake pads for our Z4 35i today and figured I'd swap out the rotors at the same time.
It looks like a couple of you have had success with the Brake Performance ones as first discussed in this thread. It looks like a front and rear set of "premium" slotted and dimpled rotors from Brake Performance will set you back $419 ($252 for the fronts and $167 for the rears). http://brakeperformance.com/brake-ro....php?did=35786 Today, I found a set of front and rear StopTech replacement rotors for the OEM brakes from an online vendor. The fronts are $150 each, or $300 for the pair. The rears are $100 each, or $200 for the pair, bringing the total for a set to $500. http://www.3zero3motorsports.com/sto...2011-z3-z4-e86 http://www.3zero3motorsports.com/sto...z3-z4-e86-rear The Brake Performance ones are supposedly made in Italy, while I wouldn't be surprised if the StopTech ones are made in China, for whatever that's worth. Though, I must say, I do like the look of the StopTech ones. They also claim to weigh less than OEM, though they don't specify how much and it gives you the impression its just boilerplate advertising copy. Does anyone have experience with StopTech replacement rotors for OEM brakes, either for the Z4 or another car? For a $81 difference, I am tempted to try them out. |

stoptech is a legit brand. They make a very nice ($) aftermarket brake systems and are an OEM supplier as well (http://www.stoptech.com/OEM)
Consider buying direct from stoptech to make sure its the genuine article.... Personally, I would skip slotted and/or drilled and just get "blank" rotors (i.e. the ones that are a solid piece of metal, like OEM. Also, I guess it is too late now, but what are your goals for the brake rotors? I think low dust is likely the only advantage of those pads.... |

Did you mean my goal for the brake pads? If so, the goal with the Akebonos is, as you say, to more or less maintain OEM braking with less dust. In our stable, the Z4 is our cruiser/show car and won't see the track. At most, it might see a couple of group runs in the canyons. Keeping the car clean is a high priority. The Akebonos are amazing compared to the OEM pad in terms of dust. It's night and day. I actually have them on the M3 at the moment, though I am set to replace the stockers with a BBK in the not too distant future. Definitely familiar with StopTech, though I do believe that most of their stuff is made in China. Might be on a nonissue, but I was just surprised to see the Brake Performance stuff made in Italy. I would have thought it would be the other way around, but apparently not. I might have to give StopTech a call to see what's up. |

I would suggest picking up the rear StopTech directly and then look at front replacements direct from bmw instead. the F30 performance brakes are a direct bolt on (front only) and are bigger than even the Euro spec 35is brakes.

How does brake balance change using the stock rear brakes and the F30 performance brakes for front? This is getting beyond my brake tech, but it is something to ask about, IMHO.
Hujan, I've had some bad luck with street, ceramic/low dust brake pads in the past. I melted a set in 1 afternoon in the canyons in a WRX. Went from 1/2" pad material to backing plate in 2 hours. Probably fine for a cruiser, but something to watch out for... |

Hujan what year is your car? My 2012 has oem pads a virtually no brake dust. I wonder if your car is older and if BMW changed the pads later on.

A guy that I know and respect very well is offering me an amazing deal on a lightly used set of Brembos for the M3. Going to be hard not to pass up. Quote:
Interestingly, the sensor for low brake pads never came on, but they are squealing like pigs and the pads appear worn. |

How were the oil temps in the M3?
Have you looked into Carbotech pads? I used a barely streetable set a few years ago, and while they squealed like crazy on the street they did not produce much brake dust and held up very nicely to track use. |

Not bad. Topped out at 250 if I recall and that was at the hottest, longest session on Saturday. I also have a pulley on there which I'm going to take off. Since it retards all the accessories (including the water pump) it obviously makes things run a little hotter. Not worth the 5-10 hp at the top end, especially as I get more into tracking.

I am going to run the OE Brembo pads in the M3 BBK for now, but I'm hearing good things about Endless pads. Ever use those? |

I've used Brembo "sport" OEM replacement in the past too, not sure if the compound is the same. They were a fine street pad. For endless, I've heard of that from more casual track users... No personal experience. The serious people seem to run Hawk track only pads then swap street pads, or accept the daily trade offs Which days are you planning to go this year? let me know your schedule if you want to coordinate HPDE days |
