If you want different wheels to those listed below, you need pcd converting wheel-spacers like Hubcentric Wheel Adaptors. as 4x100pcd is already relatively common.
What you need is simple wheel spacers in 4x100pcd, centre bore 56.6 to make the offset a little more common. These spacers would fit Vauxhall Corsa, Astra F&G, Tigra, Vectra + OPEL Ascona and are therefore pretty easy to come by and quite cheap. example of cheap spacers
