I'm currently rebuilding my front brakes, i got told when changing to 4 pots, to use the mini uprights and just the metro caliper, could anyone confirm this for me? As when i offered up the caliper their is about 5 mill gap between the caliper mount and the upright, has anyone else come across this problem?

I'm not quite sure what you mean here.

If you have kept the mini hubs, you'll need to use the drive flanges off the Metro Turbo (slightly modified) to space the disks right. You 'can' use the Metro hubs complete, but it throws the geometry out on a mini.

really silly, but what do you mean by drive flange? is it what the wheel bolts to? if so what mods do you have to do to the metro ones? Cheers

Also you need to use special caliper mounting bolts. The Metro caliper is all metric, including the bore of the retaining bolt holes but the Mini hub is imperial. You need to use some ERA Turbo type caliper mounting bolts or the caliper won't be properly held to the hub and will be able to move about. Even though they are ERA parts they are readily available from Mini specialists because this mod is so popular (but personally I can't work out why!).

Yes the driving flange is the part the wheel is fitted to. The Metro type have wheel alignment lugs that prevent any wheels other than original Metro wheels being fitted, these need cutting off flat and flush. Preferably on a lathe.

wicked, i no where i have gone wrong. so if i change the mini drive flange to metro the caliper should line up with the upright??

They should look like this but if your really stuck Griff I could come over and have a look as I don't live that far from you.

Metro 4 pots are far too heavy and give no worthwhile improvement in braking for a Mini. just stick with the standard parts - in tip-top condition - and the brakes are more than adequate. Best upgrade of course is to Fiesta single pot calipers, and then you can use the proper 10" wheels!

yep true! thats exactly what ive heard stick with decent original brakes, 4 pot metro calipers effect your
steering and handling way to much.too heavy!

Don't think weight is an issue on the road and it's an easy conversion but if you want to use proper 10" wheels then you need the cooper S ones and then the car really will handle.
