There's standard drum hubs, and disc brake hubs for minis.
The disc brake ones have the lugs for the caliper mounts.
Metro Hubs will fit a mini (with the correct ball joints) but the suspension geometry will be different. The lower arms should be replaced with negative camber ones to make up most of the difference.
If you use a Mini disc hub, the metro turbo disc, drive flange and caliper will all bolt
straight on.
The only difference is metro caliper mounts are metric, minis are imperial.
Ideally you should mount the caliper with a special bolt that has the correct mini thread and the (larger) metric shank.
