I am going to buy a lightened steel flywheel from minispares , but they warn that they are "unbalanced". How do i get it balanced and where. I`m in South Yorkshire.

Get your complete clutch setup, flywheel back plate clutch and diagram, and take to an engineering shop... don't know of any locally, however...
If your buying a complete setup from scratch, maybe worth calling MED and get it all set up before he ships...

Find a good machine shop. Simple.
Taking my crank and flywheel to my local place (EE Machining), Allen there used to do mini work. Although....this really doesn't help you much. It's a bit of an unloved art now.

Damn you good Mr Guessworks.

If you happen to have an extra crank or if the one from your engine is "out" at the moment, take that to the machine shop along with all the components mentioned above.
Most cars have a flat flange with a centering boss to mount the flywheel. Since the Mini has it's unique tapered shank crank and mating flywheel bore taper it may be difficult for a machine shop to accurately hold the Mini flywheel without the crank. What they do is spin the assembly, use accelerometers to determine the imbalance, then radially drill holes in the correct location to correct the imbalance. Therefore... it's nice to have your crank balanced prior to balancing the flywheel.

Yes,
www.med-engineering.co.uk/
Why are you going straight to med tho? Check local (unless MED is local) I found that 80% of the PROPER car places and engine shops used to either work on or with mini's. Just got to ask the oldest blokes there. Not the spotty max power people.

Just for the simplicity, that if you go to the supplier of the flywheels, then you can get everything from one place, balanced up and sent in one go !
