Unleashing a Tech Giant: A Xiaomi SU7 Ultra Carbon-Ceramic Brake Upgrade
The Xiaomi SU7 Ultra is a landmark vehicle, representing the pinnacle of electric performance and automotive technology. To complement its staggering acceleration and manage its considerable mass during high-performance driving, the braking system must be equally advanced. This case study details the installation of a **STOPFLEX Carbon-Ceramic Rotor System**, the ultimate braking solution for a truly cutting-edge car.
The Complete Performance Rotor System
This is a comprehensive, direct-fit rotor upgrade designed to work flawlessly with the SU7 Ultra's impressive factory Brembo calipers. The system provides a complete front-and-rear transformation, elevating the vehicle's dynamic capabilities.
- Vehicle: Xiaomi SU7 Ultra
- Front Rotors: STOPFLEX 430mm Carbon-Ceramic Discs with custom-fit billet aluminum hats
- Rear Rotors: STOPFLEX 410mm Carbon-Ceramic Discs with custom-fit billet aluminum hats
- Brake Pads: STOPFLEX Performance Pads formulated for Carbon-Ceramic
- Brake Lines: STOPFLEX Stainless Steel Braided Lines
Key Advantages for a High-Performance EV
Our system is engineered to enhance every aspect of the SU7 Ultra's character, from its track-day potential to its daily refinement.
- Engineered for Extreme Thermal Endurance: To manage the SU7 Ultra's ~2,360 kg mass at speed, our system is rated to withstand temperatures of 1,300°C. It is engineered to handle extreme duty cycles, such as ten consecutive 180 km/h to 0 km/h stops, without any performance degradation or fade.
- Transformative Weight Reduction for Enhanced Dynamics: Our carbon-ceramic discs are **dramatically lighter—up to 50% less than iron rotors** of the same size. This massive reduction in unsprung and rotational mass allows the SU7's advanced air suspension and chassis controls to react with greater speed and precision, resulting in a more agile feel and improved ride quality.
- Perfect Synergy with the Electric Drivetrain: In an EV, where physical brakes are used less frequently for daily driving, iron rotors can develop performance-hampering corrosion. Our **100% corrosion-proof** carbon-ceramic rotors are the perfect solution, remaining pristine and ready to deliver full power the instant they are needed.
- Zero Dust for a Flawless Finish: The SU7's design is clean and futuristic. Our ultra-low-dust pad formulation preserves this aesthetic by keeping the bespoke 21-inch wheels free from the unsightly, corrosive dust created by conventional performance brakes.

Frequently Asked Questions for SU7 Ultra Owners
Q: The SU7 Ultra already has performance Brembo brakes. Why upgrade the rotors?
A: While the factory Brembo calipers are excellent, the standard iron rotors can be overwhelmed by the immense heat generated during sustained track driving, especially with a heavy EV. Our carbon-ceramic rotors offer a vastly superior level of thermal management, eliminating fade entirely. The significant weight savings and corrosion-proof nature are also critical benefits the stock iron system cannot provide.
Q: Will this upgrade affect my car's regenerative braking?
A: Our system does not interfere with the vehicle's advanced regenerative braking, which will function as designed for everyday driving. Our kit enhances the friction braking system, which is crucial for emergency stops and for high-performance driving where regen may be limited.
Q: Is this system suitable for daily driving in a city like Taipei?
A: Yes, absolutely. Our brake pads are formulated to provide excellent response even when cold, and their low-dust, silent operation is perfect for city driving. The corrosion-proof rotors are also a major advantage in humid climates like Taiwan, as they won't develop the surface rust that can cause noise on iron discs after rain.
