Aftermarket ACS Type III Barrels?

[fiziks]

I've picked up some 2 piece, 18x8.5 +15 Type III's that I'm looking to possible widen out to something like 9 or 10 inches. Anyone know of any vendors that sell aftermarket or ACS barrels? I can't find any :(

I've never seen an aftermarket company that makes barrels for 2 piece wheels period, let alone for ACS's.
