2024-2026+ Xiaomi SU7 Ultra / Max Carbon Ceramic Brake Kit — OEM-Size Replacement
The SU7 Ultra owner is usually replacing 430 mm front and 410 mm rear factory carbon-ceramic discs after heat checking or impact damage; the SU7 Max owner is usually trying to cut heat, dust, and rotating mass from the 414 mm front and 380 mm rear iron setup. This OEM-size StopFlex kit keeps the brake package matched to the listed trim: Ultra uses the 430/410 mm carbon-ceramic layout with fixed Akebono calipers, while Max uses the 414/380 mm layout with its factory fixed Brembo front calipers. Carbon-ceramic rotors, matched pads, hats, and floating hardware are supplied together so the disc mass, expansion behavior, and pad compound are engineered as one replacement system.
- Built only for the listed SU7 Ultra 430 mm front / 410 mm rear CCB setup and SU7 Max 414 mm front / 380 mm rear setup; other SU7 trims or rotor sizes require separate verification.
- Ultra fitment is based on the OEM carbon-ceramic brake architecture with 6-piston front and 4-piston rear Akebono fixed calipers, not a caliper-conversion big brake kit.
- Max fitment targets the factory 414/380 mm rotor package and Brembo front caliper layout, giving a carbon-ceramic replacement path without changing the car’s basic brake geometry.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Xiaomi SU7 Ultra / Max |
| Model years | 2024-2026+ |
| Front rotor reference | Ultra: 430mm (CCB); SU7 Max: 414mm |
| Rear rotor reference | Ultra: 410mm (CCB); SU7 Max: 380mm |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 22" (for the 430 mm rotor) |
For OEM replacement orders, StopFlex builds around the factory rotor specification shown for this vehicle. Front floating-caliper setups require manual review before production. If the car uses aftermarket calipers such as Brembo, AP Racing, Alcon, or Wilwood, the order can still be built, but the exact caliper model, pad shape, and rotor dimensions must be confirmed before production.
This setup uses a 430 mm rotor, so the minimum wheel size is 22". Wheels under 22" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.
Why StopFlex CCB
Lower Unsprung Mass
StopFlex carbon-ceramic rotors are engineered to reduce rotor mass versus comparable iron discs, helping the suspension react cleaner and the steering feel more precise.
High-Temperature Stability
The carbon-silicon-carbide matrix is built for stable braking behavior at temperatures that can push iron rotors into heavy fade.
Rust-Free Rotor Surface
Carbon ceramic does not form orange flash rust after rain, washing, or storage, keeping the visible rotor face cleaner behind open wheels.
Long Street-Service Potential
In normal road use with matched pads and proper bedding, StopFlex CCB rotors are designed for far longer service life than typical iron replacement rotors.
Low Visible Dust
When paired with matched StopFlex pads, the system produces very low visible brake dust compared with conventional iron rotor and pad combinations.
Premium Ceramic-Glaze Appearance
StopFlex's proprietary coating creates a bright, high-end ceramic-glaze finish with subtle glaze texture and a more premium visual character behind open wheels.
Street-Usable Cold Bite
Street Spec and Track-Day Spec rotors are designed for normal first-stop road use, including cold-weather operation. Motorsport Spec is the competition-focused exception.
Continuous Fiber Reinforcement
Long-fiber carbon ceramic construction improves structural strength and thermal durability versus chopped-fiber approaches.
Custom Rotor Hat Color
Every StopFlex OEM replacement order can be built with a custom rotor hat color, giving the carbon ceramic rotor package a cleaner match with the wheel, body color, and overall build style.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat can still soak into pads, fluid, seals, calipers, wheels, and nearby components. For long track sessions, mountain descents, or sustained aggressive driving, brake cooling and high-temperature fluid are still recommended.
Street / Track-Day / Motorsport Rotor Options
Street Spec
Ceramic coating, cross-drilled face, and large cooling channels.
Best for daily driving and premium street builds that need clean cold bite, low dust, corrosion-free appearance, and long service life.
Track-Day Spec
Ceramic coating, blank face, and honeycomb cooling channels.
Best for fast-road and track-day use where repeated braking stability matters more than maximum visual drilling style.
Motorsport Spec
Uncoated blank face with honeycomb cooling channels.
Best for race-focused builds that run competition pads, high-temperature fluid, cooling strategy, and a proper warm-up window. Not the default street choice.

FAQ
Will this fit every Xiaomi SU7 Ultra or SU7 Max?
No. This page is limited to SU7 Ultra with 430 mm front and 410 mm rear rotors, and SU7 Max with 414 mm front and 380 mm rear rotors. Confirm the trim, rotor diameter, caliper type, and wheel clearance before ordering.
Does the kit keep the factory electronic parking brake and auto-hold functions?
Yes, when ordered for the correct listed rear brake configuration. The kit replaces the rotors, pads, hats, and floating hardware; it does not replace the factory rear caliper or EPB control system.
Why choose carbon-ceramic on an SU7 Max instead of another iron rotor set?
The SU7 Max is a heavy, high-output EV, so repeated high-speed stops put large thermal load into the 414/380 mm brake package. Carbon-ceramic rotors reduce brake dust, cut rotating mass, and maintain friction stability better than iron when temperatures rise.
Is this for street use, track use, or both?
It is an OEM-size replacement for street-driven and hard-driven SU7 Ultra / Max cars that need the listed factory rotor diameters. For track use, confirm pad compound, bedding procedure, wheel clearance, and inspection intervals before installation.
