Does the wheel itself have a 63.1 bore, or is that the hub diameter?  Ford FWD wheels are 5x108 with a 63.4mm bore, ostensibly to fit over a 63.1mm hub.
What offset do you need?  The Focus ST guys are upgrading their wheels and there are always a set or two of the stockers for sale: 18x8, 55mm offset, 5x108, 63.4mm bore.  Check the forums.  You can pick up some snazzy low-mile summer tires, Goodyear Eagle F1 235/40, for pretty cheap too.
If you want to see one as an example, come on over.  My summers are cleaned up and hanging in my garage.

^^^ those, only bright silver.  Lots of kids have plastidipped them matte black, I have no idea why.
