Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2024-2026+ Polestar 3. Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| Polestar 3 | 400mm | 390mm | 20" |
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
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.
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.
Winter & Cold-Weather Braking
Winter question, straight answer: untuned ceramic discs bite less when cold. StopFlex optimized the pad compound and the rotor's ceramic coating for cold operation, so cold-start braking in winter feels very close to warm-weather braking. Extra following distance on freezing first stops is still smart; severe-winter daily cars should run 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
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat still soaks 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.
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
Will this fit my Polestar 3 without new calipers?
Yes. This is a direct replacement that reuses your factory Polestar 3 calipers. The kit ships carbon-ceramic rotors sized to your car — 400mm front and 390mm rear — plus pads, hats, and floating hardware. It only applies to the exact trims and rotor sizes listed on this page, and direct replacement is valid because the Polestar 3 front caliper is a 4-piston fixed unit. Confirm your rotor diameters before ordering, since the wrong size will not seat correctly on the caliper bracket.
How do these rotors behave in winter and on cold first stops?
Honest answer: an untuned cold carbon-ceramic disc bites less than cold iron. That's normal physics, not a defect — the ceramic matrix needs a little energy in it before friction peaks. StopFlex tuned both the low-metallic resin-composite pad and the disc's ceramic coating for cold starts, so on a cold Polestar 3 the first-stop feel now comes very close to summer feel. It's still smart to leave a little extra following distance on the coldest first stops until the rotors take some heat, which on a 2.5-ton EV SUV happens quickly.
Does the kit work with the electronic parking brake on the rear axle?
Yes. The rear 390mm carbon-ceramic rotors are machined to accept the Polestar 3's integrated electronic parking brake function through the factory rear calipers you're keeping. No parking-brake recalibration hardware is added or removed — you retain the OEM caliper and its EPB actuation.
Why go carbon ceramic on a Polestar 3 instead of replacing the OEM discs with iron?
The Polestar 3 is a heavy, high-torque EV SUV, and regen doesn't cover hard braking or repeated stops from speed — that load falls on the friction brakes. Carbon-ceramic rotors resist fade far better under that heat, cut unsprung and rotational weight versus iron, and shed almost no brake dust, so your wheels stay clean. Dealer carbon-ceramic corners can run $3,000–$5,000 each; this complete kit replaces both axles while keeping your factory calipers.
