Installation is easy! Unscrew the old sign, two brackets off (this also with the old screws) clipped with a little force and the license plate. Finished! In the event that your old license plate holder has been much screwed tight, you should consider whether their new holes screwed. This is also not a problem because the land behind the number plate is so or so "invisible".
For quality itself: The license plate bracket fixes the plate extremely well and looks great. Some customers report that they had remedied because their shield sat quite loose. I can not confirm this. I have a license plate in normal size. And that is firmly seated so that I had to spend quite a lot of power, so that my plate snaps into the cradle. Even high speeds (tested to 210) easily movable.
Finally, the price is unbeatable, because the set contains yes holders for front and rear.
From me a strong buy recommendation!
