I too am considering gettin 19's....what offset is required? I have NO suspension mods yet, so clearance may not be an issue at this time. I just dont want to get tires that are too wide and rub like a b**** every time I turn. I know that I am going with a 35 series tire, because it is pretty damn small and will lessen the likelihood of rubbing. I am currently all stock with wheels and suspension. I have also heard that if you up your wheel size by more than 2" you also should recalibrate your speedometer and odometer, is this true?
