I'm located in orlando and shared_pm for contact info and research the wheels and you can find out why they are diffrent. I will go ahead and save the time for the fake wheel people and tell you. They are diffrent cause if you want a staggered offset you have to use the dunlops but then your front tires will wear like crazy. So you have to get the sprint harts for the fronts. If you would take the time to read the offset you would've figured that out.
