Is it allowed to modify air suspension in China?

It is allowed to modify air suspension in China. Modifying vehicle height adjustment with air suspension is a legal practice. Functions of air suspension: Vehicles equipped with air suspension systems can adjust ride height, as this technology utilizes air spring suspension that enables chassis elevation control. Definition of vehicle modification: Vehicle modification refers to altering the exterior styling, interior design or mechanical performance of manufacturer-produced vehicles according to owner requirements, mainly categorized into body modifications and powertrain modifications. Air suspension modification falls under legal vehicle customization. Common modifications include exterior color changes, typically achieved through repainting - though this method may cause color fading over time and damage chrome plating's luster, compromising aesthetic appeal. Alternatively, vinyl wrapping provides more durable results. All modifications must be registered with local vehicle management authorities; color changes can be implemented first before official registration.

Is the Compulsory Insurance Date the Same as the Vehicle Inspection Date?

The compulsory insurance date is the vehicle inspection date, and the annual inspection date is related to the vehicle registration date. The timing of vehicle inspection and compulsory insurance does not need to be consistent: During the vehicle inspection, the vehicle must have compulsory insurance, but the timing of the compulsory insurance does not affect the annual inspection of the vehicle. The timing of the vehicle's annual inspection and compulsory insurance does not need to be the same. The relationship between vehicle annual inspection and compulsory insurance is minimal: The prerequisite for vehicle annual inspection is having compulsory insurance, but almost all vehicles on the road have compulsory insurance, so there is no direct relationship between the timing of vehicle annual inspection and compulsory insurance. Compulsory insurance and vehicle inspection do not affect each other: From a timing perspective, the vehicle's lifespan for annual inspection and compulsory insurance does not affect each other. There is even less relationship between the timing of compulsory insurance and vehicle inspection.

Should You Buy a Steering Wheel Cover?

If the grip of the steering wheel is not unbearable, it is not recommended to install a steering wheel cover. However, if you must install one, be sure to choose a properly sized or securely fixed steering wheel cover for optimal results. Aesthetics: Steering wheel covers come in a wide variety of shapes, colors, and styles, which can significantly enhance the otherwise monotonous interior of a car. Improved Grip: For some lower-priced or entry-level models, manufacturers often cut costs, which results in the use of cheap materials and less comfortable steering wheel grips. The use of a steering wheel cover can greatly alleviate this issue.
