Haha, this guy upstairs is really funny, still playing with fire. It's okay. Who's going to open it?
This thing can't be changed by a car decoration shop.
If you want to do it, you have to find a small garage, the kind with welding. Go there and ask them to weld you an I-beam.
But first of all, the main purpose of this kind of steel beam can only be to prevent small bumps in the city.
It may not play a protective role in a high-speed collision!
Next time you buy a car, find someone with this thing. Is it annoying to make such a fuss? Japanese cars are really nothing.
