This setup has seemed to work everywhere from high bite to low bite, but I have also ran 27.5 f 25r with kyosho gold rear springs and liked it as well. As far as the gear diff I just pack it as full as I can with the black grease and you're set. Only advice I can give is when you first drive it don't point and shoot, just carry speed and ease into the throttle and you shouldn't have any trouble
