I just picked up a rear 5lug converison complete with trailing arms. Just boleted the arms in.
The problem is that my calipers wont fit the vented rotors that the conversion came with (IMG:style_emoticons/default/headbang.gif) What caliper can I get to work with the vented rotors? Or am I better off getting 5 bolt rotors that are not vented? Are 914-6 rotors vented or will they work with stock 914-4 calipers. Appreciate any advice/help. |

You can get spacers for the stock calipers.
You can use 914-6 rear rotors. You can use the appropriate 911 rear caliper. The most practical is the 914-6 rotors since you don't really need the vented rears on a -4. On a V8 I would do spacers to keep the parking brake with the vented rotors and use an aftermarket proportioning valve. Chris |

Or if your /4 rotors are good, just drill the new 5 hole pattern in them. By the way, I used the /6 rotors. |

Chris is right on
-There is a guy on this board building spacers -I'm not sure where to get 914-6 rotors -if you use the 911 caliper then you will need to adapt the 911 ebrake or find an alternative ebrake - mechanical, line lock, etc... Good luck, Felix |

Thaks for you relies.
I think i'll try to drill my /4 rotors. If that doesn't work out, i'll pick up a set of the /6 rotors from Pelican Parts. |

search for the thread:
914-4 rear brakes with vented rotor, does anybody have/make/sell the spacers? I should be picking up additional items from the machine shop in a few days. I am having the hub spacers, the caliper spacers and the longer pad pins made. To get the longer bolts and the additional O-rings you may need to find a set of scrap 911 rear vented calipers. The O-rings are a 311 part and may still be available from VW. I cleaned out one warehouse a few years ago. The bolts are very hard to find: 7mm x 70mm. As soon as I can get pictures of the final parts I'll post in the resources section. I still don't know my costs, but hope to find out this week. Like most projects, this has taken several years plus a couple of months working with the machine shop. DaveP |

Nice work Dave....I had in the back of my mind that somebody was making some spacers.
I think you will get a lot of interest. Even if they're not really necessary.....who can resist 914 candy (IMG:style_emoticons/default/rolleyes.gif) |

The kit for modifying 914/4 calipers to fit 20mm vented rotors is now in the Resources section.
