So your saying if i get 17x8 with 6.25" backspacing i will have the same exact size wheel ad i have now. Also what about offset?
Your stock wheels are actually 17x7.5, but going to a 17x8 won't cause any issues at all. And, yes, your stock wheels have 6.25" of backspacing.
As for the difference between offset and backspace....
Like I said earlier, backspace is the distance from the mounting surface that goes against your rotor to the rear lip of the wheel. Offset it the distance from the mounting surface to the centerline of the wheel. Because of this, offset can either be negative (the mounting surface is closer to the rear of the wheel) or positive (mounting surface is closer to the front of the wheel). Offset can get quite confusing.
Go have a look and play around with the calculator over at www.rimsntires.com/specs.jsp
