I have mine done. I don't have the full front, but I should have done it. So far, I can tell it saved me at least twice..
One advice I offer, get the fenders on the back wheels done too. I got a nasty rock chip there. They do stick out a bit. Not as much as on a 911 but enough to get a rock in it. I would also suggest getting the bottom part on the sides from the front wheel to the back wheel.
