Does Modifying and Removing Interior Affect the Car?
4 Answers
Modifying the interior will affect the vehicle's annual inspection. Interior modifications: Mainly involve modifications to the vehicle's electrical systems, such as installing multimedia or upgrading the stereo. However, modifications that alter the vehicle's technical parameters—such as changing the intake and exhaust systems, widening the body, lowering the suspension, modifying braking components, or blindly upgrading high-beam headlights—are not legal under regulations. Precautions for vehicle performance modifications: Converting a single exhaust to a dual exhaust is not allowed, as it may alter engine parameters. Brake calipers can be modified, as this upgrade can improve the vehicle's braking performance. Currently, domestic traffic police are relatively lenient toward modifications that enhance braking performance. Replacing or reinforcing chassis suspension components is permissible, as it can improve the vehicle's handling and stability.
I had modified the interior by removing the seats and door panels to install new covers myself, but ended up with a bunch of issues afterward. While driving, I always felt the door panels were loose, and the noise was unbearably loud. A shop inspection revealed that the clips weren't properly installed, and the damaged sound insulation affected quietness. Even worse, the wiring got loosened, potentially causing issues with the airbag sensors, which might weaken the protection function in emergencies. The air conditioning efficiency also dropped, with uneven temperature regulation. So I believe dismantling the interior is no small matter—if not done right, it can affect both comfort and safety. It's best to leave it to professional shops.
Interior modification can be quite interesting, giving your car a fresh and personalized look, but it comes with significant risks. I tried it once—when replacing the carpet, I found the sound insulation layer was torn, leading to noticeably increased wind noise at high speeds. The main concerns lie with the airbag system and wiring; improper disassembly can cause misalignment or damage, increasing safety hazards. Additionally, replacing original parts affects the car's integrity and may lead to warranty disputes. For safe modifications, it's advisable to thoroughly research or consult experts—don't take risks just to save money.
Interior disassembly and modification directly impact safety. Airbags may fail to deploy properly due to obstruction, leading to loss of protection. Wiring faults can trigger warning lights. Removing sound insulation materials increases noise levels, distracting drivers and potentially causing accidents. Warranty coverage may also be voided, affecting long-term maintenance costs. Therefore, such operations require caution, with priority given to preserving the original factory design.
