If you want to do a car wheel modification for your BMW, who knows a more professional wheel modific

Tires are like shoes for a car. Pick the right pair of shoes so that you can run fast and walk steadily. A car with excellent driving performance needs other systems to balance it in addition to a strong powertrain, and this is especially true for modification.

Car wheel modification is a more important step in the car modification, whether it is the appearance of the modification or the improvement of handling performance, the wheel hub has played an important role in it, the last time my pony replaced the wheel, the recommendation of the rider came to Tianrong Hongdeli, with the help of the master selected a high-quality wheel, under strict inspection, to ensure that its personality parameters are qualified. Fabulous.

If ready to be retrofitted to a satisfactory look and performance. Need to spend more than 20,000 yuan on wheels and tires, which is the lowest number, those low-cost wheels can only be used for a few weeks will be deformed, and even bought is not round enough. I have bought two BMWs before, the BMW shock absorber itself is tough enough, the tires are too thin and the body will continue to shake, there is no comfort at all, it is recommended not to change, I bought a high configuration of 535, tires 245 45 18

But I'd rather use thicker tires, which don't have much impact on driving, but have a big impact on comfort.

If you modify very thin tires, you have to change the wheels, this can be modified, generally car boutiques or tire stores have, shock absorbers are best seen on the Internet, there are many brands.

1. Don't try to buy fakes cheaply.

The modification of the wheel hub is a more important step in the modification of the car, whether it is the appearance of the modification or the improvement of handling performance, the wheel hub has played an important role in it, a high-quality wheel, after the rigorous production process and strict inspection, to ensure that its personality parameters are qualified. If the economic conditions do not allow for the time being, please choose the modified wheels carefully, although the original "steel rims" and "cast wheels" may not be beautiful and lightweight, but at least the safety is guaranteed.

2. Choose the right wheel hub correctly.

The role of the wheel hub to enhance the appearance is more obvious, but when choosing the wheel hub, every detail must be taken into account, the various parameters of the wheel hub will affect the use of the wheel hub and the vehicle, the PCD value is incorrect may not be able to install normally, the ET value not only affects the installation and use, but also may affect the future upgrade and modification.

3. Ensure that the wheel hub is installed correctly.

It does not matter, but the insurance company's compensation is also based on the original wheel tire ** compensation, and the excess part is borne by itself.

1. First of all, you have to see how many inches the wheel hub of the customer's car is and how many inches you want to upgrade. For example, the original car is 16 inches, and it can be upgraded to 17 inches or 18 inches.

2. Determine how many inches to upgrade, for example, the customer wants to upgrade to 18 inches, well, then you can find 18-inch wheels, you only need to provide 18-inch and the customer's model, those wheel brands or modification shops, you must know the preliminary specifications of the wheels: hole spacing and center hole. For example, the hole spacing of the winged god is, the center hole is, as soon as you talk about the model, they all know it, they will find out the ** of the eligible wheels for you, and you choose a few favorite styles.

3. Pay attention to the brand, modified wheels, there are generally 4 categories, the worst is domestic unbranded, followed by domestic branded and Taiwanese imitation, these 2 kinds are almost the same, the best is imported. Ordinary cars can use a domestic brand or Taiwanese imitation, imported wheels are too expensive. The cheap one also costs 4,000 a piece.

4. Look at the weight and J value of the wheel, in the second step, it is only a preliminary selection of the hub that can be installed, and this step is to choose a more suitable one. The lighter the weight of the wheel, the less power loss and lower the fuel consumption, the greater the J value, the wider the wheel, the wider the tires, although the grip and handling will be improved, but the loss of low torque, and at the same time, the front wheel will be easy to dry up in the full direction. Choose a suitable wheel with the right weight and J-value.

Generally, aluminum alloy wheels are lighter in weight.

5. ET value, this data mainly affects the space of the brake and whether the wheel hub is protruding or concave. The higher the positive ET value, the more hub space there is, and the easier it is to install the brake kit. For example, 17-inch wheels generally have to be ET35 or more, so it is easy to install brake calipers with four pistons, and if you want to install brake calipers with six pistons, then the ET value is even greater.

6. After the modification of the wheels, it is necessary to equip the appropriate tires, so that the number of clear strokes in the state can remain basically unchanged.

If you still don't understand, you can take a look at this information: the concept and precautions of ET value.

When it comes to modifying a car, many people's first reaction is to change the wheels. Because the original wheels are either too "ordinary" or too "mediocre" (I can't feel like I can soak mm). I went to the modification shop to take a look, there were a dazzling array of wheels, and I didn't know where to start, and the store had a stand-up comedy, which made you say in the clouds.

Casting "forging" which wheel is best for you?

As the saying goes, only the foot knows whether the shoe fits or not, and we should also avoid some misunderstandings about the choice of wheels.

Budgets are everything.

The grade of the wheel hub is very different, when buying the wheel, you must be clear about your budget and needs, and at the same time you must understand the market, shop around, otherwise it is a sheep into the tiger's mouth.

Cast wheels. Casting wheels are divided into gravity casting, low-pressure casting and spinning casting.

Gravity casting is to pour liquid alloy into the casting mold to cool and form, which is the lowest cost casting method.

Low-pressure casting is to use low pressure to press the liquid alloy into the casting mold, so that the molecular distribution is even, the pores are less, the metal density is high, so the strength is stronger, the safety factor is higher than that of gravity casting, and there are more modeling options.

Spinning casting first makes the prototype of the wheel hub, and then through special equipment, the cast wheel hub is reprocessed and rotated stamping, so as to further strengthen the density of the wheel hub material and achieve higher strength requirements.

The advantages of cast wheels: low, diverse shapes, bent and deformed by impact, not easy to break.

Forged wheels. Forged wheel hub is through thousands of tons of high pressure, a piece of alloy that has been heated into the rough embryo of the hub, and then use CNC detail carving secondary processing, due to the impact of high pressure, so the molecules between the alloys will be smaller, the gap will be finer, the density will be higher, and the interaction force between the material molecules will be stronger, so the hub only needs less raw materials to achieve enough rigidity, so that the overall weight of the hub is lighter.

Advantages of forged wheels: light weight and high rigidity.

Little Pony concluded.

Cast wheels, with a certain toughness, are not easy to break when impacted, but easy to deform, cheap can meet the daily safe driving, the disadvantage is that the weight is heavier affects the performance of the vehicle, acceleration and deceleration, fuel consumption will have an impact, but since the decision to modify, the budget is limited, it is recommended to buy a set of spin casting wheels are cheap and can be comparable to the sturdiness of forged wheels. Forged wheels have a lower weight, which allows for better handling and sportiness, and higher strength makes for safer driving. In the end, how to choose depends on your wallet.

The quality of the wheel hub is related to driving safety, and you can't buy inferior products cheaply.

When we choose the right wheel hub in the modification of our own car, we must first understand that in the face of different models, the choice of wheels should also be different, do not think that what kind of wheels you want to change can be replaced with what kind of wheels. Wheels are mainly divided into steel, aluminum alloy and magnesium alloy wheels. Steel is the heaviest, but the price is the cheapest, aluminum alloy wheels are lighter than steel wheels, magnesium alloy wheels are lighter and softer than aluminum alloy, and the acceleration performance is better, but magnesium alloy is mainly used for racing, so magnesium alloy wheels are only useful in places with excellent road conditions.

There is also the need to upgrade with the tires, and you must pay attention to the upgrade with the tires when the car modifies the wheels, because the size of the tires itself has a close relationship with the size of the wheels. There may be car owners will choose second-hand tires, which is actually an irrational behavior, after all, there is a certain gap between the texture and life of second-hand tires and new tires, and it will also bring certain hidden dangers to driving safety. Therefore, new tires should be selected for wheel modification and upgrading.

And the size of the wheel hub has become larger, and the brakes and shock absorbers have to be adjusted, because in the process of your car modification, in addition to considering the modification limit, the modified shock absorber is the best match. Good quality shock absorbers can reduce the damage caused by ground bumps to the chassis, and the reinforced suspension not only enhances stability, but also maintains the comfort of the vehicle during the ride. Good performance shock absorbers can lower the car's center of gravity, so that the vehicle can be more stable when hitting the dust when going straight or cornering, and with the tires will have better grip, giving the driver a very flexible handling.

You can't blindly increase the wheel hub for the sake of beauty or performance, because some car owners think that the bigger the wheel, the better, and the wider the tires, the better, but in fact, this idea is not scientific.

On the one hand, the diameter of the wheel hub is too large, which will increase the torque and increase the load when the propeller shaft is rotated, so that the power of the vehicle during starting and acceleration will be weakened. In addition, when we use large wheels, we must match tires with a flat rate, because the friction contact area with the ground increases, and the friction will also increase, which will make the fuel consumption higher. Finally, the replacement of wide tires will increase the load on the steering wheel, which will not only affect the handling of the steering wheel, but also shorten the service life of the steering machine.
