As per previous threads, my car has had a 5-lug conversion - I think correctly done. The front hubs/rotors/calipers are 914-6/early 911 ones as far as I can tell (ATE calipers), I therefore assume the rear hubs/rotors/calipers might also 914-6 or similar? Can someone confirm? TIA
 Just for laughs, Google's Ai analysis of the photo tells me it's from a Nissan Primera P12... (IMG:style_emoticons/default/lol-2.gif) |

OK, so they changed the hubs and rotors for 5-lug… but the 5 lug rotor has basically the same dimensions overall as the 4-lug one, so it fits with the stock -4 caliper? Is that how it works?

Is that how it works? pretty close... if you stay with non vented rotors... the OD of the 5bolt rotor gets turned down a tiny amount... to work on a 4 cylinder set up. |

OK, that's interesting, thanks... Just trying to understand all what has been done here. The disc does have a part number on it - 901 352 401 18 - and it does appear to be a 914/6 disc...   The OD of the rotor part is around 285mm (11.2") as well as I could measure while still on the car. From the traces on the edge of the rotor, it appears that it might even be rubbing slightly on the spring clip... So maybe these weren't turned down?  Anyone have the outer diameter specs for a /4 rear disc vs a /6 disc? Doesn't look like much could or should be turned off, the pad-swept area on the rotor starts in about 3mm from the outer edge. Also have been unable to find a part number on the rear caliper, just the ATE logo... Here's what it looks like from the inside. Definitely dual bleeder fittings.  |
