I run many FZJ80 series parts on my 4-Runner, including the 12" brake system, and it works beutifully on the lighter rig. Many of you seem to be having issues with them in the application for which they were designed. If there is interest, I'd be willing to look into a 'BIG brake' upgrade for the FZJ80. The stock calipers could probably be retained, and if they'll fit into the 16" wheel, a 13" rotor would probably fit the bill quite well. Not looking for profit here.... not really sure how far I'll even go due to the lawsuit factor... brakes are serious stuff.
