Offset is just where your wheel would sit at. Our stock wheel, the offset is +45. The higher the number is, the wheel would go inward like the front of a USPS mail truck. The lower the number the wheel comes out. Correct me if I'm wrong, I think it's right unless it's the other way around.
Whatever offset you want I would stay in between 42-45 but thats me, Everybody is different
