Andy,
Which Boxster caliper did you install. Actually, I don't know anything about Boxster calipers; are standard different than "S" ? Thanks, Andys |

I have had Boxster calipers on my six for about 3 years now. Love them. No lockup, and it stops with NO fading at all.

Very cool. 914 that I drove with these on was really night and day different from my then 911s front with M rears. Your car must be a blast on the track and AX courses. (IMG:style_emoticons/default/piratenanner.gif)

Finally upgraded my brakes like Andy had done. Was running Boxster front and Carerra rear. Using Rich Johnson's beautifully made adapter the task was uncomplicated and as Andy described, but simpler in my case as I went with the SC rotors (20 mm) vice the Carerra (24 mm). I had been running the 24 mm rotors but thought that I'd give the 20 mm ones a try and if I have heat/warping issues can always perform the rest of the mod later and go to 24 mm rotors.
My brake lines had enough room to thread into the caliper without a banjo like Andy used. Looking forward to trying out this upgrade next month at my first event of the year at Buttonwillow.      |

Andy - Great job and the brakes look great. What, if anything are you doing regarding brake bias? Do you intend to use your car on the track? With all that volume it will be interesting to see if you end up with a larger MC. I had a 19 and moved up to a 23/930. Food for thought and always a slippery slope...

Don't know what Andy is running for a M/C but I have a 23 mm and it was a very hard pedal with the Carerra/Carerra and Boxster/Carerra combo. I think that it will be very good and easy to modulate with the Boxster fr/rr combo. |

I think i'd like a little more leveraged feel with something in the 21mm range, but I would imagine the 19mm being a little more travel range than I'd be comfortable with. I am curious what pads people are using for the 914, given the lack of vacuum assist and generally cooler operating temps (in my case anyway). |

I have to bleed the brakes again, so i can't comment on the pedal feel just yet. It did feel a bit soft after the first bleeding, but that was to be expected. As for the bias, i have been running with a "T" for years and so far, it feels OK. The real test will be my next AX where i plan to really put the brakes to the test. I'm hoping to get the fronts to lock up first but have enough bias to the rear to make them work hard. We'll see how that pans out ... (IMG:style_emoticons/default/chowtime.gif) |

Is there an emergency brake as part of this solution?

Yeah, at 150+ into a downhill 90-degree corner... I like a HARD pedal, knowing the brakes are REALLY there. Auto-x is completely diferent...your "life" is not on the line. Keep us posted as you are able to get some time with the brakes. Once again, it's an attractive set-up! |

i have boxster S calipers too. (IMG:style_emoticons/default/poke.gif)
i would love to do this to my 914 too, the boxster is 50% heavier than the teener and stops on a dime- this is going to be great on the track with your teener! (IMG:style_emoticons/default/beerchug.gif) i dont have a track car, so would be overkill i think for my 2.0, but maybe the BMW upgrade might be worth it? what do you advise- i am on a 4 lug ...

I too have boxsters on my 914...
Question for you peeps... did you orient the rear calipers so the larger piston was the leading piston? (i.e. LR becomes RR, and RR becomes LR, and you have to flip the bleeders to the top, and the x-over to the bottom). Or did you just bolt them on, and let the smaller piston lead? (I see a mix of the above on this thread) |

I flipped the oil feed lines so they are the same as the Boxster. I think the small piston is on top. Can't remember but I made sure it was the same as the Boxster. I am also running a 19mm master cylinder and I am quite happy with it for street and autocross.
