Hey Roberto, if you're genuinely after some proper man sized wheels like that, get your head around Yahoo Auctions Japan. If you don't have an auto-translating web browser, you can use http://www.importmonster.com.au/yahoo . It's where all the real gems are hidden to most of us english speaking folk.
Generally, just navigate to automotive>car parts>rims>14"/15"/16" on the side, and punch something in like 10j, 11j, 12j, SSR, WORK, that kinda thing.
There's a guy; jessestreeter.com, who will buy rims on your behalf, pack them up and send them via sea freight to you. About $100 per rim for postage and can take 8-12 weeks.
