Full analysis of wheel hub upgrade in car modification

In the field of car modification, wheel hub modification is one of the projects that many car owners are enthusiastic about. It not only brings a refreshing visual effect to the vehicle, but also plays an undeniable role in improving performance. A suitable modified wheel hub can make your car stand out in the vast sea of cars and optimize the driving experience.

1、 Why do we need to modify the wheel hub
From an appearance perspective, the design of original wheel hubs tends to be conservative to meet the universal aesthetic preferences of most consumers. The modified wheels come in a variety of shapes, from simple and stylish single spoke designs to complex and powerful multi spoke styles, and even unique shapes such as hollowed out and petal shaped designs. Car owners can freely choose according to their own vehicle style and personal preferences, making the vehicle more recognizable. For example, a sports car with smooth lines paired with a set of sharp and large-sized wheels can further enhance its dynamism and sense of speed; A sedan with a strong business atmosphere, when paired with a set of exquisite and atmospheric multi spoke wheels, can add more luxury and stability atmosphere.
In terms of performance improvement, the role of the wheel hub is also significant. Firstly, high-quality modified wheels usually use lighter materials such as aluminum alloy, which can effectively reduce the unsprung mass of the vehicle compared to traditional steel wheels. For every kilogram decrease in unsprung mass, it is like a four kilogram decrease in the overall mass of the vehicle, which means that the acceleration performance of the vehicle will be improved, the braking distance can be shortened, and the steering will be more responsive. Secondly, modifying the wheel size reasonably, such as increasing the wheel diameter appropriately and matching it with tires with corresponding flat ratios, can increase the contact area between the tires and the ground, thereby improving the vehicle's grip. In scenarios such as high-speed driving, cornering, and slippery roads, stronger grip can make the vehicle travel more stable and safe, effectively reducing the risk of losing control.

2、 Key points to note when modifying wheel hubs
（1） Material selection
The mainstream wheel hub materials on the market currently include aluminum alloy and steel. Although steel wheels have a relatively low price and a certain degree of flexibility, and have the possibility of repair after being hit to a certain extent, their disadvantages are also obvious. They are heavy, which increases the energy consumption of the vehicle, and the appearance style is relatively simple, which is difficult to meet the needs of car owners who pursue individuality. Aluminum alloy wheels have become the preferred material for modified wheels due to their advantages of light weight, high strength, and good heat dissipation performance. It can not only effectively improve vehicle performance, but also create rich and diverse shapes through various advanced manufacturing processes, meeting the dual pursuit of beauty and performance of different car owners.
（2） Consideration of size
Car owners need to be extra cautious when modifying wheel hub sizes. According to relevant regulations in our country, changes in wheel hub size must be within a reasonable range, otherwise it will not pass the vehicle annual inspection. Generally speaking, it is recommended that the upgraded wheel hub size should not exceed two inches of the original wheel hub size. If the wheel size is blindly increased, it may lead to a decrease in the power performance of the vehicle, because the rotational inertia of large-sized wheels increases, and the engine needs to output more energy to drive the wheels to rotate, which will slow down the acceleration of the vehicle and significantly increase fuel consumption. In addition, oversized wheels may interfere with the suspension, brakes, and other components of the vehicle, affecting normal driving and even posing safety hazards.
（3） Matching of data
The data of the wheel hub is crucial for the success of the modification and the driving safety of the vehicle. Among them, PCD (pitch diameter) determines whether the wheel hub can be correctly installed on the axle head of the vehicle. If the PCD value does not match the original vehicle, the wheel hub will not be able to be installed. The size of the center hole (CB) must also be precisely adapted to the wheel axle of the vehicle, as being too large or too small may cause the wheel hub to shake during driving, affecting driving stability. The offset distance (ET) affects the position of the wheel hub after installation. If the ET value is too small, the wheel hub will be too convex, which may cause friction with the vehicle's fenders and other components; If the ET value is too high, it will cause the wheel hub to shrink inward, affecting the vehicle's handling performance. Therefore, when choosing to retrofit wheels, it is important to ensure that all data matches the original car perfectly, or to make reasonable adjustments under the guidance of professionals.
