The risk is that the offset will be too low which rules out the opportunity for spacers to help matters!
I'm unsure what offset is critical on a 19" wheel but I reckon it'll work regardless providing you fit the 'right' tyre (poss. undersized to give additional clearance).

There was a gorgeous refurbed set for sale with perfect non ///M Z3 offsets on eBay that did not sell for c1200 euro on Spanish eBay. They may come up cheaper soon
