WTB: BBS or generic blank step lip barrels 20x11+

[maglito]

Does anyone know a source (anywhere) for BBS replacement barrels (they do make a 20x11) or another manufacturer that will sell just step lip barrel blanks in wide (11"-12") 20" diameter sizes?
PM me please if you can help point me in the right direction.
These are going on OEM 20x9.5 BBS LM-R wheels.
Thanks!
