From the website:
Rim combinations are as follows- We now have even more tooling to produce a wider range of rims, now up to a max of 10" wide.
Inner Rims- 2" - 2.1/2" - 3" - 3.1/2" - 3.3/4 - 4"- 4 3/8" - 4 3/4"
Outer Rims- 2"- 2 1/2 - 3" - big 3" - 3.5" - [95mm, Miglia spec outer] - 4"- 4 1/4"- 4 1/2" - 5"
From that I'd reckon you could piece together a set to fit under the body without arches?
Since the smallest outer available there is a 2" , even if you ran 2" inner and 2" outer with face mounted centers, your offset would still be too low for an archless car. (10x4 ~ ET 7mm)
These are the 3-piece wheels I picked up for an archless car. 10x4 with high offsets akin to the rosepetals/minilites/steelies often found on archless cars.

I've also found the "big dish 10" section below with the following info. If you had a 3" inner and a 1" outer you could make it work... that would be around +25 on a 4" wide wheel
Or 1" outer and 4" inner would be around +38 on a 5" wheel
Individual spun rim widths are, 1", 2", 2.5", 3" and 4".
Customers should look to use either the 3" or 4" rims as inners, and then adding any of the other 5 choices to the outside.
