Offset is usually stamped or engraved into the wheel and is measured in millimetres of 'ET' [ET is the short form of the German word 'Einpresstiefe' which literally translates as 'insertion depth'] Positive Offset wheels have their mounting face toward the front face of the wheel. Most front wheel drive vehicles have positive ET wheels. Eighties and Nineties Volkswagen wheels are usually ET38.
Zero Offset wheels have their mounting face even with the centerline of the wheel and are by definition "ET 0". Negative Offset wheels have their mounting face toward the rear of the wheel - powerful rear-wheel drive cars often have wheels with negative offset.

And the scrub radius will be wrong.

I appreciate your help on this, it's an education. I guess 12mm (or close to) spacers would work to maintain the original setup as I'm keen not to alter things too radically.
Trouble is using the 1010 wheel offset calculator you kindly pointed me towards seems to suggest the 'track' would be wider rather than narrower as you have suggested, is this because of positive as opposed to negative wheel offset?
