for those of you not following the other thread on this. I decided after much consternation and information gathering. To do it. What was it?
I put my 914-4 front calipers on the rear of my track car. I have vented SC rotors on the front now with M calipers loaded with Porterfield R-4E track pads. On the rears I plan on running basic street PBR pads. I am going to try this at a one day event I am instructing at. If it still has too much rear bias then I am going to install an adjustable bias valve. Pic of offending piece of equipment. Attached image(s)

We're gonna find out, me thinks (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif)
Personally, I think a adjustable bias valve would be a good plan in any case.....it's more like roullette without bullets. (IMG:http://www.914world.com/bbs2/html/emoticons/huh.gif) |

We tried to tell him that in the other thread but "Mr. Smartypants" had to go his own way! (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) I think they'll be OK with the pads but it's hit or miss until or if you get the right combo. I 'really' like the Rear M-Caliper with the spacer removed idea... (IMG:http://www.914world.com/bbs2/html/emoticons/idea.gif) |

"If" he's still alive folks! (IMG:http://www.914world.com/bbs2/html/emoticons/w00t.gif) Just fun'n wit ya... Based on what you wanted I think those M's would be cool. For those who weren't playing along at home: The idea is to take a pair of rear 911 M-Calipers and remove the spacers. This is for guys and gals who are racing with 911 brakes up front that want a nice matching caliper (read; 38mm) in the rear. No handbrake of course. Without the spacer these would run on 914-4 or 914-6 rear rotors. Should 'bolt on'. Advantages: Side mount brake line. Same piston setup used in a 911 and 914-6. No fancy rotor needs. More consistent pad setup. |

Don't forget: Disadvantages: No parking brake. Car is no longer street legal in any state. Your insurance company could quite possibly deny you coverage, even after they have taken your money, if your car is in any kind of incident leading to questions about the brakes. The Cap'n |

Wow, and how many 914s have functional handbrakes? Equipment may be there but how well do they work. Can't remember the last time I saw one on a hot/street rod either.

I went with SC vented rotors in the front and back. Using SC calipers in back and 320i calipers with big pads in the front. Just hope I never have to park on a hill and my insurance company can bite me. (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif)

Sort of like Everest. They were there. New calipers, dirt cheap, and they came with the 911 suspension I bought. Guess I have redefined caliper roulette! (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) |

makes perfect sense to me....kinda like why I decided to try the fronts on the rear....they were there and didn't have those hoakie adjusters on them. (IMG:http://www.914world.com/bbs2/html/emoticons/sad.gif)

You don't have to worry about me Greg. I don't gamble (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) Really.
I plan on being very cautious and build up to see what I have. You will be in front of me any way.. . remember when your car was a stock 2.0L. I have a momentum car anyway...don't need brakes (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) Much (IMG:http://www.914world.com/bbs2/html/emoticons/ohmy.gif) |

Well I wonder if any of our illustrious members will be my students for BW?
Would be interesting to say the least. (IMG:http://www.914world.com/bbs2/html/emoticons/wink.gif) Hank usually tries to set newbies up with instructors that are very well versed in the car they are instructing in. I get lots of Boxsters and 914s ( when 914s are in attendance) |

Dan,
On my last 914 I had M calipers with Hawk Black pads in the front, a 'T' in the line, and the stock 914 front calipers moved to the rear with some generic carbon metallic pads. The bias felt great on the street and track, but I never got a chance to run it aggressively in the rain. That's where bias issues can really show their ugly heads. It appears the car I have now has vented rotors in the rear with M calipers all around, and I have no idea what the pads are either. I haven't driven it yet, but it could be an experience.
