After buying a car, many friends will want to decorate their new car or buy some modified parts to personalize it. However, some modified parts with higher performance or better appearance are more expensive. Some friends who only care about appearance may settle for second best and buy some non-genuine products. As everyone knows, using such modified parts or decorations will not only compromise performance and appearance, but may even endanger driving safety. So which "modified parts" must not be purchased? Here is an inventory for you.

Copycat aluminum alloy wheels

I believe that many friends will consider changing to a better-looking set of wheels after buying a car, especially the low-end models using steel rims. Generally speaking, genuine brand-name aluminum alloy wheels are generally more expensive due to their exquisite manufacturing processes and materials. For example, one of the most popular products, RAYS TE37, uses a single-piece forging process, which is very lightweight and rigid. The price of an ordinary 17-inch product is several thousand yuan or close to 10,000 yuan. Popular high-performance wheels such as BBS LM cost 20,000 yuan for a 17-inch wheel. Even the spin-cast products of domestic famous brands such as ARTKA cost close to 2,000 yuan for an 18-inch piece. The ultra-lightweight RAYS CE28 is the favorite of many small car owners. The price of a 15-inch unit exceeds 10,000 yuan. In comparison, the so-called "Taiwanese-made", "Taiwanese-made" and the same type of rims sold by Taobao only cost 3,400 yuan a piece, and can even be created in special sizes that are not available in the original factory, making them popular. Shy players welcome.

BBS LM is the best-selling two-piece forged wheel from Japan BBS. Its classic tuning fork shape and excellent quality are the favorite of performance cars.

A single rim of a 17-inch product costs more than 20,000 yuan.

LM adopts a two-piece structure, and the rim and rim are fastened with screws. This design can provide a more complete range of rim sizes to suit more models.

The copycat BBS LM 17-inch product only costs less than 700 yuan a piece, and the price is more than ten times lower than the original product.

Shenma Forging does not exist. It is just a one-piece casting made by a copycat workshop. The quality and shape cannot be compared with the genuine product.

Some friends may have said that foreign products are too expensive. These knock-off rims are cheap and have a certain similarity in appearance. Moreover, he does not race cars, so these products are the most suitable for him. This idea is completely wrong. First of all, the production process and materials of these knock-off rims are not as good as genuine products, and all the testing procedures are not perfect. Therefore, the materials are uneven, the manufacturing process is poor, and the quality is very uncertain. Regardless of whether it can have a good dynamic balance, it cannot even meet the basic requirement of a perfect circle, causing abnormal vibration when driving.

Another player’s favorite is RAYS’s TE37, which has a forged six-spoke design and is extremely rigid and can also be used in racing cars. This wheel rim has become the hardest hit area by copycats.

TE37 copycat version only costs 340 yuan a piece. The key is that except for the first generation TE37 (which is out of print),

’s current TE37 does not have 15 or 16 inches. The copycat factory is really capable of everything.

Vossen is a favorite of European and American players who play posture, and the look is quite good. Genuine Vossen CVT uses a forging process.

Even so, because the spokes are very thin, genuine Vossen CVT and CV3 rims also have the reputation of "the king of bells".

And the cheap forged products from the counterfeit products dare to launch such thin-spoke wheels. Do you dare to buy them?

There are also some genuine products that use forging technology and are extremely rigid, so the spokes can be hollowed out thinner to achieve a lightweight effect. However, counterfeit workshops can only use the worst casting technology to manufacture spokes. Such thin spokes cannot withstand slight impacts and are easily broken, seriously endangering driving safety. Therefore, if a cash-strapped player wants to replace the rims, the best way is to buy second-hand genuine products, or purchase genuine rims from other models, and resolutely say no to counterfeit rims.

A genuine factory forged or cast wheel with reliable quality can maintain a certain degree of integrity even if it encounters an emergency impact. This is to reduce the safety risk caused by a tire blowout.Like the AMG original forged aluminum rims in the picture, even if part of it is exploded, the whole thing can still remain intact.

Counterfeit products often have all the spokes broken at the same time, causing great driving danger. Some low-quality rims can even be blown apart by the air waves from a puncture.

In addition to the spokes, the rim body of inferior rims is also quite weak in terms of impact resistance. Relying on such rims to ensure life safety can only be a joke.

Counterfeit brake calipers and counterfeit caliper shells

Some friends want to change to a good-looking brake kit after changing their wheel rims to make the wheels look fuller. However, genuine brand-name brake kits such as Brembo, Alcon, and AP Racing are not cheap, so many unscrupulous merchants sell fake brakes as genuine ones at special prices, or pass them off as good ones. For some brake kits, some businesses will even use genuine calipers with knockoff brake discs and knockoff accessories to increase profits. And this kind of brake kit that seems to be cheaper is also more difficult to identify the authenticity. As a result, many car enthusiasts think they are getting a big bargain when they buy, but in fact they also create hidden dangers for safety.

Many people change their brakes not to make them stronger, but to fill up the rims and make them look fuller. This is the soil for copycat inferior brakes.

only needs the AP 5200 package that costs NT$3,000, including calipers, floating discs, brake pads, brake steel pipes and brake fluid . Such a package seems to be a good deal, but with a brand from a world-renowned manufacturer and a price comparable to original parts, do you dare to buy it?

The color of the brake disc, do you dare to tell me that it is genuine? What kind of heat treatment has this low-quality steel just undergone?

Since the brake caliper itself is a component that withstands high pressure and high heat, under high temperature and high load, poor quality brake calipers will cause internal oil circuit failure, piston stuck, abnormal deformation, etc., or even cause non-linear brake vibration. , which may seriously lead to brake failure. The strong torque exerted by the brake disc on the brake caliper at the moment of braking can easily cause the joint part of the counterfeit brake caliper with poor material and heat resistance to burst and cause the entire brake caliper to fall, seriously affecting driving safety.

Counterfeit calipers can easily break in a high-heat environment and under heavy-duty braking, and the consequences can be imagined.

Counterfeit brake discs will also suffer adverse effects such as cracking and deformation under frequent braking and high temperatures. Some copycat split brake discs may even break and disintegrate the disc and closing screws. Copycat brake steel pipes cannot withstand too much pressure. The joints and pipes are prone to bursting and oil leakage, resulting in loss of brake pressure and loss of braking effect.

If the quality of the modified floating brake disc is unreliable, the tragedy of the closing screw part being torn off may occur.

brake caliper housing is also a "decorative part" favored by many "auto parts city style". Some brake caliper casings are made of plastic, which can easily melt due to the high temperature of the brakes. In mild cases, it will affect the heat dissipation of the caliper itself, causing the brake to easily overheat and fail. In severe cases, it will melt between the brake pads and brake discs, causing brake failure, or high temperature fire. Although some brake calipers made of metal will not melt, they can easily fall off under constant vibration and slight collisions, causing serious accidents such as wheel rims and brakes getting stuck. Therefore, to improve braking in a cost-effective way, you can choose high-performance brake pads and brake fluid, which is always much safer and more effective than buying a copycat brake kit.

In addition to looking inferior, it is not uncommon for brake caliper covers to fall off due to vibration while driving, jamming the brakes and rims, causing loss of control. It is not uncommon for accidents to occur.

steering wheel covers made of various materials

I don’t know when the steering wheel covers started to emerge. According to the explanation on "Some Degree", the steering wheel covers can protect the steering wheel from wear; increase the feel and friction; and prevent the hands from sweating. Skidding; enhancing the response sensitivity and safety of the car when driving; reducing vibration absorption. The material is usually elastic rubber, leather or plush.Let’s not talk about the quality of the material and whether it increases the feel. From a safety perspective, you must take off the steering wheel cover.

Do you believe that furry steering wheel covers like this can increase safety?

Generally speaking, the steering wheel cover is placed directly on the steering wheel without any reinforcement measures. During use, dust and debris can easily accumulate between the steering wheel cover and the steering wheel. At the same time, the steering wheel cover is fastened by elasticity. After being used for a long time, it is easy to lose elasticity due to long-term stretching, so the steering wheel cover is easy to slide on the steering wheel. Sometimes when turning the steering wheel in an emergency, the steering wheel cover slips and the steering wheel is not turned fully, which can cause danger. At the same time, when turning the direction, your fingers can easily get stuck in the gaps in the steering wheel cover, causing unsmooth movements and easily causing distraction. Therefore, from a hygienic and safety perspective, never use a steering wheel cover.

Copycat xenon and LED light sets

Many low-end or entry-level models still use halogen headlights, and their brightness and "handsomeness" are somewhat inferior to those of xenon models. So many friends have started thinking about modifying xenon headlights or LED headlights. However, since halogen headlights and xenon headlights have different specifications, voltages, control programs, etc., they cannot be directly replaced. So you need to use some set of light sets. Some well-known brands will have corresponding modified products for corresponding models, such as Bellof, PIAA, OSRAM, etc. However, due to its high price, many friends have started to think of doing it themselves and buying some cheap xenon headlight sets. However, in addition to being improperly installed and unable to achieve the desired effect, this type of lamp unit is more likely to cause safety hazards.

Worldwide brands like Bellof have strict standards for lamp design and requirements, which are unmatched by ordinary workshop-style products.

First of all, xenon headlights must have lenses to ensure that the light is concentrated and not diverged. However, to install xenon lenses on halogen headlights, the headlights must be disassembled and specially adjusted by a master. Many xenon headlights sold online do not have lenses, and direct installation will cause the light to diverge. In addition to poor lighting effects caused by insufficient gathering, oncoming pedestrians and vehicles will also be illuminated by divergent xenon headlights and unable to see the road ahead, increasing traffic risks. Generally speaking, the color temperature of general xenon headlights does not exceed 5000K, and some unbranded xenon headlights adjust the color temperature to more than 5000K in order to increase the lumen, which will also affect the line of sight of oncoming cars due to excessive light.

The products of some workshops will blindly pursue range and brightness. If you can see clearly, the other party will not be able to see clearly, which will also cause driving dangers.

Xenon headlights must use ballasts . The quality of the ballasts produced by some copycat workshops is uneven, and the voltage is unstable and generates serious heat. In addition to being prone to malfunctions, short circuits and spontaneous combustion may occur, or the entire vehicle circuit may be affected. . Therefore, if you want to modify xenon headlights, you must use qualified products from major manufacturers and find a professional master to adjust and install them. You must not install some substandard xenon headlight products naked.

Here are four very common "modified products" on the market. Although the price is not high, it will always give people the illusion of "high cost performance", but it will have very big hidden dangers for driving safety. The most basic bottom line of modification is to ensure or even improve safety performance, and this point cannot be compromised. Therefore, friends who want to modify such products should think twice. They would rather save money slowly and choose genuine products with good quality.
