Thanks everyone! I'm actually starting to like these more than the factory rims lol.
I got them from a company that imports used parts for Japanese cars from Japan in Mississauga - PM me if you're in the Toronto area and want the name. They are in decent shape. The date stamp on the inside of the wheel says they were made in 2002, but I don't think these were ever driven in the winter, because they don't have any corrosion - just some scratches.
I'll grab a pick of them from the side this weekend.
