Expensive car accessories may not bring many benefits
Many people often install car accessories to improve the performance of the car, but that does not necessarily bring benefits, they can even damage the car.
Install a balance bar for the engine compartment
Stabilizer bar or tie bar for cars is an equipment that can be available with the car or added as an additional car accessory. Stabilizer bars are installed in many positions of the car frame to increase the stability of the car body, reduce drag and torsion of the car frame.
According to a survey by VietNamNet, the main choice of Vietnamese customers is the balance bar installed in the engine compartment, with prices ranging from 2,000,000 VND to several million VND, depending on the brand. Because this equipment usually only appears on sports and high-performance models, when installed on popular cars, many people think that it helps the engine compartment look more or less sporty.
According to driving safety training expert Nguyen Hong Vinh, for a car to operate stably, the first core thing still has to come from the car, which already has a good enough chassis, suspension system and safety features. With high-performance sports cars, manufacturers have designed stabilizer bars to optimize driving feel as well as rigidity.
Meanwhile, to achieve such stability in a popular car, the user needs to install many balance bars in different positions on the chassis. If only one balance bar is installed in the engine compartment, this will certainly not bring about obvious results, if not to say it is unnecessary, Mr. Vinh shared.
In addition, many auto experts believe that adding a stabilizer bar can affect the technical structure of the vehicle, and the manufacturer can completely refuse to provide warranty if there are problems related to operation.
Cheap soundproofing materials
Noise is something that most ordinary drivers encounter. Therefore, understanding this psychology, car care units and auto accessories businesses often advise customers to overcome it by installing soundproofing materials, which can reduce noise by 45-80%.
However, after a period of installing soundproofing, many car owners have had to remove it. Not only that, the areas where the soundproofing panels are installed on the car also cause water to accumulate, making the car frame susceptible to termites and rust, damaging the car's components, causing the car owner to "lose money and get sick".
Mr. Chu Van Thuong, owner of Scar Workshop, a car audio store, said: "To soundproof a car, the cost will range from 20-30 million VND. For popular cars, many car owners may only choose cheap products that cost only a few million VND, but the quality is not guaranteed, so it is easy to encounter risks during use."
Not to mention, many car owners often have the mentality of comparing prices, then choosing the place with the cheapest cost. During the installation process, cheap places will often use fake, low-quality soundproofing materials. In addition, the level of the workers is not guaranteed due to lack of proper training, which can completely lead to the above incidents.
Therefore, users should proactively choose reputable establishments. Remember that soundproofing and noise reduction for cars depends on many factors and to achieve the desired soundproofing quality, the price will not be cheap, Mr. Thuong emphasized.
Rubber cushion for shock absorber
In recent years, many users have known about the shock absorber rubber pads installed on the shock absorber of the car. According to the seller's advertisement, the shock absorber rubber pads only cost from 200,000 to 3,000,000 VND. The effect of this accessory is to reduce the vibration of the car when traveling on bumpy roads, increase the ground clearance of the car, help the shock absorber to be sturdy and increase the life of this part.
However, automotive engineer Le Van Tach commented that the downside of installing additional shock absorber rubber pads is that when carrying a light load, it will increase the height of the vehicle body, making the vehicle unstable and unsafe when cornering. In addition, installing additional shock absorber rubber pads that do not meet the manufacturer's standards will likely cause the vehicle to be rejected for inspection.
Another technical aspect that users need to pay attention to is that when installing this rubber pad on the spring, it will shorten the working length of the spring, increase the stiffness of the spring, increase the free oscillation frequency of the spring, leading to breaking the overall stability of the suspension system, the engineer added.
Therefore, installing shock absorber rubber pads on the spring set requires expert advice, otherwise installing this accessory yourself will be useless and even unsafe for your vehicle.
Nylon car ceiling cover
On popular cars today, the car ceiling is mainly made of felt. This is a cheap material, with effective sound absorption and heat insulation. However, this material often gets dirty quickly, retains odors and quickly becomes old over time, causing the car to lose value when the owner wants to transfer it.
Therefore, many car owners, especially those who use their cars for service, often choose to cover the car ceiling with nylon, in addition to other materials such as imitation leather, PU synthetic leather or suede. However, nylon is still the most popular choice because of its low price, around 300,000-500,000 VND, does not attract dirt, does not retain odors and is easy to clean. In addition, when it is necessary to return to the original for transfer, users can easily remove it.
But besides these advantages, Mr. Le Dang Trung, CEO of Chung Auto car tuning center, assessed that covering the car ceiling with nylon will also cause certain inconveniences. Specifically, people sitting inside the car will feel uncomfortable because it feels noisier and more humming than usual.
This is because the smooth nylon surface does not have the ability to absorb sound, when stretched it will create a vibrating membrane causing the sound to bounce back to the ears of the person sitting in the car. Moreover, the car ceiling is often curved, so when wrapped in nylon, it will be difficult to hug the surface, affecting the ventilation of the car ceiling. Nylon is a material that is easily torn, so when torn, the car owner will be forced to re-cover it.
