Rehooping ?

[orang-kr8]

I found my dream wheels!!! But, they are not made anymore

Question is I found a set on craigslist and they are for a BMW.
The bolt pattern will work but I would like to make the wheel wider and change the offset to fit my 70 chevelle.

ANYBODY HAD ANY EXPERIENCE WITH REHOOPING A 18'' WHEEL?

IS IT WORTH THE TROUBLE?

WHAT WOULD IT TAKE TO MAKE IT 18X11?

P.S. THE WHEELS IN THE PICS ARE NOT THE WHEELS IM LOOKING AT, BUT A SET ON EBAY HAD BETTER PICS

THANKS!!!!
