I've just have my stock fj40 wheels widen in southern california, the inlaws is picking them up for me today
Let you guys know how it goes next year. It's done by Bolton Classic Wheels in Gardena, California (use Yahoo Yellow Page to look up the phone/address), after my set they increased the price to 65 bucks each (used to be 55 bucks).
Depending on how wide youa re looking to go, you can track down a set of the Sahara rims for the FJ60 that were offered in desert regions as an option on the FJ60. They come from the factory as a 15x7 instead of the 15x6, I can get some pics of mine if you're interested.
