just to clear things up :
wheel spacer
wheel adapter
note the 1st one is illegal, despite being OEM on some dodge, and toyota trucks.
the second is not illegal as it bolts to the axle,then the wheel bolts to it. making this illegal will make all duallies illegal as they all come with these in the front (usually cast iron, and shaped abit differently).
i run 2" wheel adapters myself. thats as wide as i would go because of stress on steering components. you might consider different offset rims as well.
they do make doing anything that requires taking the rotor off a PITA since you are instructed to loctite them on. That may make a trail repair take longer.
You want the front axle to be a little bit wider than the rear axle, because it is easier to steer, and tracks better. Thats why a bunch of toyota guys run the spacers up front when they have the ifs axles.
Plus, the Toy IFS rear axle is about 1.5" wider than a Toy front axle.
