No idea, but most 18" japanese rims would sell for $2-$4k depending on make model etc etc inc freight from japan. I was looking at some racing hart wheels and they were around $800 each inc freight. I have been able to source some enkei's quite cheap, $500each from sydney + $20/rim to freight. A friend sold me 2 18x9 enkei rp01 rims (they dont make them anymore, but the rp02 is pretty much the same) 2nd hand and I'm gonna order 2 new 18x8 rp02's from sydney in a month or 2. At $500/rim new I think they are the cheapest jap rim you'll find in 18". Then you've got 18" rubber on top of that, for good dunlop rubber its $600/tyre, falken is around $400/tyre cheapest performance tyre I've found is a simotoma around $300/corner.
