Compared to genuine Japanese Fit, our European Jazzes have a black plastic base for mounting the front license plate. I don't like the look of this bulge, as it makes the front look even longer and heavier. So I took it off to find out what are the possibilities to mount the license plate in more sleek way.
Beneath the black plastic bulge there is a smaller protrusion which has the size and fixing points to fit a Japanese 330x165 mm license plate. While a plate close to this size is available in Finland, it is a special plate and costs ridiculously much. Our standard EU license plate is 442 mm long but it is also available per request without EU-sign on 397x118 mm size. And that's what I have.
I ended up to mounting the license plate directly to original mounting points. Even when the mounting screws are on top edge and both ends of the plate are without backing, the mounting feels sufficiently firm. Besides this makes the car at least 1 cm shorter.
I'd wish there was no protrusion at all, but didn't want to shave the bumper either.
In rear I used original mounting points on hatch and no back plate. Just drilled and threaded the plastic inserts for M6 screws and mounted the plate vertically 7 mm off-center, which I think looks better.
BTW for just out of interest, the license plate fixing points in front have M6 thread inserts on 210 mm distance and in rear plastic inserts for 5 mm self tapping screws on 240 mm distance.
