Easy to get any wheels you desire, companies like the one above will make wheels to order in many sizes and fitments so you'll never need spacers ever again, just find a wheel you like on their designs and order it in any diameter/width/offset and PCD that you want, just be sure to be absolutely correct in your measurements before placing an order.
If you don't like a design of theirs then just speak with them to get the design in your head down on CAD. And that's just a UK company there are others all over the world looking for your custom and to expand their design base.
Just google custom made alloy wheels loads out there
