Sounds good, but then the plate would be above the grill and you'd see the mounting bracket below it which would look c**p
No, you'd take the mounting bracket off it
It's the plastic bit that's part of the bumper that will still show. Arrowed in the attached picture.
There is a metal bracket that screws over this for the JDM number plate, but obviously they are a different shape completely.
Still looking for a better way
Get a motorbike rear shrunk down plate. That'd look sweet! It's illeagal but take it off if you get pulled for it!
