[RC51V2]

Without getting off the main thread, b/c this is thread is exactly what I was looking for, can someone simply explain to me what difference I will notice on my truck if I fit a 17x8 wheel with +25 offset/backspace v. the same wheel with 0 offset/backspace. I'm confused how the same wheels (American Racing) fit, but have different offset/backspace measurements. Does it mean one wheel is going to stick out of the fender more? Or is something going to rub on the fender or when I turn at full lock? I really like the Sidewinders but I want to be sure I know what I am getting into before I shell out $ for a set of wheels that might look great in a picture but not fit right.

TIA
