Where to get large offset mags

Can anybody suggest where I can get some 5 x 114.3 17" mags with 55mm offset. NOBODY in oz has any.
The largest offset that anybody can offer is 45mm.:bigthumb:

You'd probably only be able to get them custom made if you have tried everywhere already. I suggest trying the australian wheel companies such as ROH, speedy and HR racing as a start.

Tried all them.
