ok, well you already have a +2 axle in the rear, i dont think its necessary to go wider than that in the rear. You could flip your fronts though, VoOK has it and im planning on doing the fronts as well. The only thing is the valve stem will hit the caliper so you need to dismount the tire, drill a hole and mount a valve stem on the inside of the rim and flip the other one inside out so it soesnt hit the caliper.
