Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2023-2026+ NIO ET5T. Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| ET5T | 355mm | 330mm | 18" |
Keep Your Factory Calipers?
Yes — if your front factory calipers are fixed 4-piston or more. The rear axle has no restriction. Cars with 1- or 2-piston floating front calipers should use the Full Upgrade kit (calipers + discs) instead. Discs are built to the factory rotor specs shown above; if you run aftermarket calipers (Brembo, AP Racing, Alcon, Wilwood), we simply confirm the caliper model, pad shape, and rotor dimensions before production.
Spoke profile and offset also affect clearance — confirm your exact wheels before ordering.

Why Carbon Ceramic — and Why StopFlex
Long Street-Service Life
In normal road use with matched pads and correct bedding, one StopFlex CCB rotor set is engineered to outlast several sets of iron replacement rotors, recovering part of the up-front cost.
Low Visible Dust
Matched with StopFlex pads, the system sheds a fraction of the dust an iron rotor and pad combination throws. Wheels stay clean for weeks of driving instead of days.
Premium Ceramic-Glaze Finish
StopFlex's proprietary coating gives the disc a bright ceramic-glaze surface with subtle texture — the factory carbon-ceramic look, clearly visible through open wheel designs.
Continuous Fiber Construction
StopFlex discs are built with long continuous carbon fiber instead of chopped short fiber. Continuous strands carry load across the whole rotor body, raising strength and thermal durability under heat cycles.
Bespoke Per-Vehicle Engineering
Every order is machined to the confirmed vehicle and trim. Brackets, hat offsets, and pad shapes are built for that exact car — never pulled from a one-size-fits-all catalog.
CCB-Specific Pad Compound
A low-metallic resin pad compound reinforced with steel, copper, and aramid fiber, made for ceramic discs: stable to about 750 °C, roughly 0.44 average friction, strong fade resistance, low rotor wear.
Lower Unsprung Mass
A carbon-ceramic rotor weighs roughly half of the equivalent iron disc. Less rotating, unsprung mass lets the suspension follow broken pavement more cleanly and makes steering response noticeably sharper.
High-Temperature Stability
The carbon-silicon-carbide friction matrix keeps working at temperatures that push iron rotors into heavy fade, so the tenth hard stop feels like the first — same pedal travel, same bite point.
Rust-Free Rotor Surface
Ceramic discs cannot flash-rust. After rain, a wash, or weeks of parking, the rotor face behind your open-spoke wheels stays clean — no orange ring on a freshly detailed car.
Winter & Cold-Weather Braking
A cold, untuned carbon-ceramic disc needs more pedal than iron on the first winter stops — normal material physics. StopFlex engineered the pad formula and disc coating specifically for cold starts, closing that gap: cold-car winter feel is now very close to summer feel. Keep a little extra distance on the coldest mornings; for harsh winters, choose Street Spec.
Choose Your Rotor: Street, Track-Day, or Motorsport
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.
Heat Management Note
High rotor temperature tolerance does not mean heat management disappears. Under repeated hard braking, heat migrates into the pads, brake fluid, seals, calipers, and wheels even when the ceramic disc itself is comfortable. Plan brake cooling and high-temperature fluid for extended track sessions, long mountain descents, or sustained aggressive driving.
Get Your Fitment Confirmed
Before ordering, tell us the exact vehicle, current rotor sizes, and caliper type. Nothing goes to production until the build is confirmed against your VIN-level configuration.
FAQ
Does this fit my ET5T without changing the calipers?
Yes, as long as your car uses the factory front caliper this page is built around. This kit replaces the 355mm front and 330mm rear factory rotors with carbon-ceramic discs on new hats and floating hardware, then reuses your original NIO calipers and mounts. Direct Replacement is only valid when the front factory calipers are 4-piston or more, which is why fitment is locked to the exact ET5T trims and rotor sizes listed. If your rotor references match, you bolt on and go.
How do these behave on a cold winter morning?
Physics first: an untuned cold carbon-ceramic disc bites less than cold iron on the very first stops. That's normal, not a defect. StopFlex tuned both the pad compound and the disc's ceramic coating specifically for cold starts, so first-stop feel on a cold ET5T now comes very close to summer feel. On the coldest mornings, leave a little extra following distance for your first one or two stops until the front 355mm discs come up to temperature, then they're fully responsive.
Will these reduce brake heat when I slow this heavy EV from highway speed?
That's the main reason to run them. The ET5T is a 2.2-ton-plus EV, and stopping from highway speed dumps a large amount of kinetic energy into the rotors as heat. Carbon-ceramic discs handle sustained high temperatures far better than iron and resist the fade you get from repeated hard stops. Paired with our carbon-ceramic-specific pad (about 0.44 average friction, heat resistance to roughly 750 C with strong anti-fade behavior), the front axle stays composed on long descents and repeated braking.
Does this work with the electronic parking brake and my current wheels?
Yes. The rear 330mm discs are designed to work with the ET5T's factory rear caliper and its electronic parking brake function, so your EPB continues to operate normally after installation. Because you keep the factory calipers, wheel clearance matches your current setup, but always confirm your wheel and spoke clearance before install, especially on aftermarket wheels.
