I found that the 100mm (which is 1.6mm smaller than the 4") will work just fine when using a spacer to convert to the larger bolt pattern. You do not have to modify for the 1.6mm difference, you just have to use a thinner wall socket when tightening the lug nuts. They are much cheaper than having custom ones made. I was quoted 65 per for the custom and paid 65 for the pair from another site. Just wanted to pass the info on that the 100mm will work.
