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.

If you don't put the screws, any of the disks could move on assembly making that wheel out of balance.
I decided to source original parts instead of "modified" ones. Mike |

"On assembly" you trust some mook at Discount Tire Express to make sure your disks are centered ? You might take the time to do it right. Mike |
