How to legally modify a car's body kit?

[Alivia]

First, you need to apply for a modification registration at the vehicle management office. A decision on whether to approve or reject the modification will be made within one working day from the date of acceptance. If the vehicle management office approves the body kit modification, you can proceed with the modification. After completing the modification, the owner must return to the location where the modification registration was processed to submit the original and photocopy of the vehicle owner's ID, the vehicle registration certificate, and other required documents. Submit one vehicle photo from the "Motor Vehicle Registration Form (Supplementary Form)" to the vehicle management department of the local traffic police branch (or headquarters).
