What are the regulations for modifying vehicle interior seats?

[JohnDella]

Removing seats from the interior of a vehicle is considered illegal modification. Vehicle modifications mainly include two types: body modifications and power modifications, such as braking systems, suspension systems, engine power, etc. Simply removing seats to install floor mats is generally not considered illegal modification, similar to replacing tires with different brands but the same model. Relevant information about vehicle modifications is as follows: 1. Regulations: According to the motor vehicle registration regulations, any changes to the body color, model, performance, purpose, or structure of a licensed motor vehicle, or replacement of the frame, body, or engine, must be reported to the vehicle management office for modification registration. 2. Benefits of modifying rims: Installing a good set of rims can improve heat dissipation and achieve lightweight goals, providing high visual impact both statically and dynamically, and enhancing the vehicle's handling performance. Increasing the diameter and width of the rims and reducing the flatness can overall improve the tire's grip.
