 Will 951/944 turbo calipers fit under 15" fuchs?, Lets make an adapter to make them fit :) |

2 questions -
1) will they fit under 15" fuchs? 2 ) i know they are 3.75" spacing....and you can slot the ears to fit on a 3.5" strut... would an adapter be feasible to mount them to a 3" spacing strut? |

I believe so... I have a set here. I can try a mockup mount and see.
I'm contemplating mounting options as well. Let me know what you come up with. Eric |

they seem like a nice alternative to boxtsers...
the adapter is what the hitch will be... and i bet you need to make them sit further inboard on the rotor... they are deisgned for a 298mm rotor |

Do you mean "Baby Brembos"? The 4 piston black ones that say PORSCHE. I thought the 951 fuchs were a little bigger to accomodate those brakes.
see part num 951.362.115.00 on http://members.rennlist.com/911pcars/WheelWts.html Of course that might refer to the Turbo S calipers or M030 calipers. I guess this begs the question, which 951 calipers? There is 2 or 3 versions. EDIT: The 1986 turbo was the only one with early offset wheels, so those fuchs would have to be for that car. Also, I "think" that car would have had the baby Brembos. TurboS didn't show up until 1988 and I am not sure when M030 package was available. Of course the 914 has smaller rotors so....... I guess the only way to know is to try. I'm sure Eric will be able to give you a good idea. |

I am sure they would need a spacer.
I have the 951 brakes on my car but am using the 951 16"x 7 and 8 rims, I have both the Fuchs and Phone Dialers. I think they fit the 15" diameter just barely but will need to be spaced out from the hub. I am using the calipers with the 84 Carrera rotors. |

I have a set up front - had struts modified by Rich Johnson 'bout 10 years ago to fit the 3.75" spacing. Imagine that would be an option for 3" struts as well, if he still provides that service. He told me at the time that 15" fuchs would not fit. They're tight under 16" fuchs, so I'm inclined to believe him.

yes, ran them on my old car. I ran 15x8's all the way around. Ran with a 15mm spacer to kick track out more, not for clearance.

I have 944 turbo calipers all the way around.
The fronts have to be redrilled to fit the 3.5" bolt spacing. The rears had to have a custom mount fabricated. No, the 15" wheels will not fit over the calipers. The 16" wheels are a tight fit. |

Starfleet issue tractor beam... (IMG:style_emoticons/default/biggrin.gif) Actually it's a 911 P-brake with custom made cables. The mount holes are redrilled on the calipers, which sets them inward some. Plus to get them to fit, you have to use 911 Carrera rotors, which won't fit under 15" wheels. I guess if you offset drilled the holes even farther inboard, you could use stock 911 vented rotors. Boxster rotors are different, and the mounts are custom fabricated to make them fit under the 15s. I hate to tell you this, but the volvo calipers have the wrong offset and diameter to work with 911 rotors. I know... I tried them. Plus they are cast iron, and are really heavy. |

I know all about the volvos.. sitting on my shelf FOR that reason.. heavy? loaded is lighter than a 911 A caliper!! LOL (but yes still heavy) i think it can be done. im going to do it i think. Bracket wont be tooo hard.. ill ahve someone cad it up in solidworks for me.... and i think i know where i can *BOrrow* a 911m strut/hub/rotor from how did you do the rears? welded on a new mount with 3.75" spacing?

AA I cut the mounting tab completely off the trailing arm. Then I made a new one that matched the bolt pattern for the 944 turbo caliper. I used a junk caliper that I took the pistons out of, then drilled the backs of the piston holes. I threaded the holes and put long bolts in them. A set of used pads enabled me to clamp the caliper on the rotor, and a set of digital calipers allowed me to check that the brake caliper would be centered on the rotor. Then I tack welded them to the trailing arm. I took the jig caliper off, and removed the rotor, and welded the mounting plate in place. What sucks is that I got the caliper a little higher on one side than the other. (IMG:style_emoticons/default/headbang.gif) But with a 23mm master cylinder and cross drilled rotors, I have what Betty refers to as "Hand of God" stopping power. Plus the brakes impress the rice boys...... (IMG:style_emoticons/default/happy11.gif) If I were going to do it again, I would use Boxster Monoblocks. Easier to install, and less fabrication. Or use a Brembo Big Red kit for all 4 wheels (pricey). It would bolt on with no fabrication. |

fun!
im going to buy a pair and play with em... i know someone who just bought some 911M struts i can probably borrow for mockup and adapter design.... hmmm... i like the rear weld on idea.... gee... dirk wright |

ill know more at mockup.... but this is what i have in mind....
i think it can work pardon the drawing.. its late.. and it aint solidworks time LOL  the curve on the mounting ears of the caliper has me thinking all of the corners on the adapter will need to be beveled...  |
