If you want the flexibility of removing the plate and not see unsightly screw holes, check out Skene Design. At least the screws go in vertically on the underside of the lower bumper/grille. Bonus is that it's a minimalist design with no plastic backing bracket. I use it on my other car and it looks great being mounted lower than grille height. When I don't need to go into downtown much, I'll run without a plate.
On the F15, I didn't bother since it's my wife's DD and isn't modded much with front/rear MPerf spoilers, etc.
