Mid to high end car performance upgrade: the art of brake modification and wheel hub upgrade
For mid to high end car users, vehicles are not only means of transportation, but also carriers of driving pleasure and personal expression. In the field of modification, the upgrade of brake system and wheel hub is regarded as a core project that combines practicality and aesthetics, and the reasonable disposal of original car accessories is an indispensable part of the entire modification chain.
Brake modification: dual evolution of safety and performance
The original brake system of mid to high end car models can meet daily use, but it is still insufficient in intense driving or complex road conditions. Upgrading the braking system usually starts with multi piston calipers, such as the front six and rear four piston calipers from brands like Brembo and AP Racing, which can significantly improve the linear output of braking force; Paired with high-performance brake pads (such as carbon ceramic or low metal formulations) and perforated and lined ventilated discs * *, it can effectively solve the problem of thermal attenuation and shorten braking distance by more than 30%. It is worth noting that the modification needs to be matched with the original ABS and ESP systems, and some models need to recalibrate the brake proportional valve through professional equipment to avoid compatibility issues with the electronic system.
Wheel hub upgrade: balance between lightweight and aesthetics
As the "shoes of the car", the wheel hub directly affects the handling performance and visual impact. Mid to high end car owners often choose forged wheels, which are made of T6 aviation aluminum material, which reduces weight by 40% compared to original factory cast wheels, can reduce unsprung mass, and improve suspension response speed. If you pursue visual tension, you can choose large-sized wheels of 20 inches or more, paired with narrow front and wide rear tires (such as 255/35 R21 rear wheels), which can enhance grip and create a sports car like posture. When selecting, it is necessary to strictly check the ET value PCD、 Center hole data, if necessary, install a variable diameter ring to ensure installation accuracy. For air suspension models, it is recommended to upgrade the adjustable tilt lever simultaneously to avoid interference between the wheel hub and wheel arch.
The value cycle of original car accessories
The disassembled original brake calipers, wheel hubs, and other components still have a high residual value. OEM parts with relatively new condition can be circulated through 4S store certified second-hand channels, and some luxury car original wheel hubs can have a premium of up to 60% in the second-hand market. It is recommended to keep at least one set of original brake assembly for quick restoration in case of annual inspection or warranty disputes. For the dismantling parts of limited edition models, they can also be included in the brand's officially certified classic car parts library, forming a unique automotive cultural asset.
During the modification process, it is necessary to adhere to the principle of "data first", use 3D scanners to obtain the original chassis parameters, and use professional software to simulate the stress changes after modification. Choosing modified parts certified by TUV or DOT can ensure legal compliance and provide technical endorsement for future resale value of used cars. Through scientific modification, mid to high end cars will undergo a transformation from "mass-produced industrial products" to "personalized precision machinery", truly unleashing their engineering potential.
