If you observe the side view, the gap between license plate and bumper it just few mm. When pressure is applied on plate, it will rest on the bumper ( I tested that). Also, that is the reason the mounts material is thin unlike those commercial one and bends easily.You mounted your plate holder to that lower grill.
10MPH front bump and that grill cracks and is $800 ( not installed ).
Also trimmed length of screws those holding plate from bottom so that those would not protrude and scratch in case of hit on license plate. I will try take a photo later.
BTW, some folks expressed issue about shutters. There is quite a bit of gap between the grill and actual shutters. Grill is a separate piece and should not be that expensive for that insert.
