I had two rear hubs done but none of the holes for the brake disc mounting screws were lined up and the hackjob of drilling and countersinking new holes in the brake disc was something I didnt like.
The mounting holes in the hub are oriented 180 degrees apart from what I can tell. The holes in the 914-6 brake disc are more like 175/185 degrees apart. Is there any particular way that is better than the others for orientation of the hub vs the brake disc? I want to be able to give as clear instructions as possible to the machine shop.

(IMG:style_emoticons/default/confused24.gif) Take him a rotor and hub. The 914 and 914-6 use a different hole pattern ( same as 911) for the rotor to hub screws. Either redrill the hub to match the rotor or rotor to match the hub. Also be aware that the 914-6 rotor is 4mm larger in diameter. If you are using 914 calipers they will rib. Either need to grind out caliper metal or turn down the rotor to fit. One way is not better than the other. Or you can forget the screws as the rotor is going nowhere once the wheel is on. Bruce |
