With the rapid advancement of EV technology, owners are demanding more than just straight-line speed; they want sustained performance and long-term durability. The Xiaomi SU7 Max is a powerhouse, but its factory braking system can be a limiting factor for enthusiasts who want to unlock the car's full dynamic potential.
Carbon-ceramic technology is the answer. By offering superior heat resistance and massive weight reduction compared to traditional metal brakes, the STOPFLEX Carbon-Ceramic System has become the top choice for discerning owners. This case study details a complete overhaul using TTSPORT calipers to create a braking system that is lighter, stronger, and more durable.
The Complete Performance Build
This build features a comprehensive front-and-rear Big Brake Kit (BBK) designed to manage the SU7's mass and torque, fitting perfectly within the 20-inch wheels.
- Vehicle: Xiaomi SU7 (Max)
- Front Calipers: TTSPORT EB8 8-Piston Calipers
- Front Rotors: STOPFLEX 405mm (15.9 in) Carbon-Ceramic Discs
- Rear Calipers: TTSPORT 4-Piston Calipers
- Rear Rotors: STOPFLEX 380mm (15.0 in) Carbon-Ceramic Discs
- Brake Pads: STOPFLEX High-Performance Ceramic Pads
- Hardware: Custom mounting bridges, bolts, and TTSPORT stainless steel lines
Important: System Compatibility
This case study features a full Big Brake Kit (BBK) conversion using aftermarket fixed multi-piston calipers (TTSPORT). Our STOPFLEX carbon-ceramic rotors are engineered to pair with this specific high-performance hardware.
Please note: These rotors are custom-configured for the TTSPORT kit and cannot be directly installed with the factory Xiaomi calipers. A full caliper upgrade is required to use this specific setup.
Key Advantages for the SU7 Max
- Extraordinary Longevity: STOPFLEX carbon-ceramic rotors are manufactured from carbon-fiber-reinforced silicon carbide at temperatures exceeding 1700°C (approx. 3092°F). This process creates an incredibly durable disc. Under normal driving conditions, provided the ceramic layer is not compromised by track abuse, these rotors offer extraordinary longevity compared to iron.
- Efficiency & Range: STOPFLEX carbon-ceramic discs are over 50% lighter than comparable cast iron rotors. In an EV, reducing this rotational weight not only improves handling agility but also reduces the load on the electric motors, potentially contributing to better energy efficiency and range.
- Fade-Proof Endurance: The drilled carbon-ceramic rotors effectively resist heat fade, maintaining stable friction coefficients even under high-intensity braking. This is crucial for safely stopping a heavy, high-performance EV repeatedly.
- Corrosion-Proof Reliability: Iron rotors on EVs often rust due to the frequent use of regenerative braking. STOPFLEX rotors are corrosion-proof, ensuring they remain clean, effective, and visually pristine regardless of weather conditions.

Frequently Asked Questions for SU7 Owners
Q: Why choose an 8-piston caliper for the front?
A: The SU7 Max is a heavy vehicle with supercar-level acceleration. An 8-piston caliper provides a massive brake pad surface area and evenly distributed clamping force. This maximizes stopping power and thermal management, ensuring the brakes can handle the immense kinetic energy of the vehicle.
Q: Does this upgrade affect the car's warranty or electronics?
A: This is a mechanical upgrade. While it significantly improves performance, it operates independently of the car's software. However, as with any major modification, we recommend consulting with your local specialist regarding specific warranty terms. The system is designed to work seamlessly with the car's ABS and traction control.
Q: Is this kit suitable for street driving?
A: Yes. Despite the track-level hardware, the system is refined for street use. The pads offer excellent cold bite, and the virtually no-dust performance keeps your wheels clean during daily commuting.
