one aspects of the Wilwood hubs I didn't like was that the hub centre is tapered, not really providing adequate support for the wheel to register on. I didn't want all the wheel load to be carried by the wheel studs. Also the brake hat internal diameter didn't provide a solid register (was slightly too large) again leaving the wheel studs to do the locating work. I fixed this and had a internally tapered shrink fit register made.. you can see it in this picture . this is a solid register for the wheel & brake hat:
