These wheels are up there in the Extremely rare category with very few sets been observed for sale.
Most examples I have seen for sale have been relatively narrow in the 6-7" wide range which don't seen to get much interest and sell for relatively low prices , but recently, a set popped up on Yahoo Japan that proves there are some wide sets out there!
The set above are 8" and 10" wide with unknown offsets. The 10s defiantly have some serious negative offset though. They are not in the best condition and missing the bolts and centre caps but still got a whopping 130,000Yen! Or around $1400Aud. Which I guess really isn't too bad for wheels this size and of this rarity even if the condition isn't the best.
The only information I can find on these wheels is the scan above High Top Fades Park had uploaded a while ago on his facebook page. You can see they were made from 5.5" to 11" wide in 13 and 14" diameters. So the set above was defiantly in the higher end of the scale! I love seeing these old scans and seeing that would could get a set of 14x11s for a tiny 32,000yen!!
These are defiantly one set of wheels Id love to have in my collection! =)
Also Id love everyones suggestions on what wheels to do next week? Thinking of doing a special on some old school aero or maybe the Super Star range?
