Well, here's the answer I got from MSI who handles Compomotive in the US.

[[Sorry for the delay in this response but it was just forwarded to me. We are unable to help you with your request as Compomotive has decided not to restock the 15" and 16" inner and outer rim sections and we have not been successful in having them spun with good quality at a fair cost. MSI is not selling modular wheels or sections at this time.

It looks like my alternatives are to have someone section the back half of the 2 front wheels, or investigate replacing the stock stamped upper control arm with a 5/8 inch narrower tubular control arm.
