Will 19x9.5 ET15 cause rock chips on doors?

[tbenson5]

First off, I am a new owner of a 370z, had a 350z for 3 years and did aftermarket wheels with decent offset to flush out the wheels. I notice on the 370z that the top of the fender is out further then the bottom of the fender and front bumper.
Im looking at getting a set of forgestar f14 19x9 deep concave with +15 on the front. I know this will flush it out on the top but my question is whether that much poke on the bottom will cause rock chips along the door/side panel.
Anyone have any experience with this? Ive considered getting a clear bra just not sure if I would do the whole door or just cap the bottom.

Any feedback would be appreciated. I could just be overly worried but since the car only has 7k miles and no dings at all I would love to keep it that way as long as possible.
