Polestar 2 Carbon Ceramic Brakes Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2021-2026 Polestar 2 Carbon Ceramic Brake Kits
The Polestar 2 is a heavy EV fastback that splits between a standard 345 mm front setup and the Performance Pack’s larger 375 mm Brembo front brakes. Buyers usually care about keeping daily civility while adding more fade margin and reducing unsprung/rotating weight on a car that can still be driven very hard.
- Body style: Fastback
- Front rotor reference: Perf: 375mm; Std: 345mm
- Rear rotor reference: Perf: 340mm; Std: 320mm
This is an OEM-size replacement kit. The rotors are built to the factory rotor spec and install with the factory caliper when the front caliper is a fixed design and the rotor spec matches. The included pad shape matches the OEM pad shape. If the car uses aftermarket calipers such as Brembo, AP Racing, Alcon, or Wilwood, provide the exact caliper model and StopFlex can supply the matching pad shape. Direct replacement is not confirmed if the front caliper is floating, or if the car already runs a non-OEM-offset rotor and the actual rotor dimensions cannot be supplied.
Why StopFlex CCB
Lightweight
Half the Weight, Sharper Handling. StopFlex carbon-ceramic rotors shed roughly half the mass of equivalent iron discs. This massive drop in unsprung weight instantly transforms your chassis, delivering sharper turn-in response and a significantly more refined road feel.
High-Temp Resistance
Minimal Brake Fade at 900°C (1652°F). While traditional iron rotors severely fade under heavy track loads, our CCB matrix holds a stable 0.30μ friction coefficient even at 900°C (1652°F). You get consistent, predictable stopping power when things get dangerously hot.
Corrosion Resistance
100% Rust-Free Durability. Say goodbye to flash rust after a car wash or heavy rain. The carbon-silicon carbide material is naturally impervious to corrosion, ensuring your brake rotors look completely clean and pristine no matter the weather conditions.
Long Lifespan
250,000+ km (155,000+ mi) Lifespan. Iron rotors typically require replacement around 100,000 km (62,000 mi). In normal street driving conditions, a StopFlex CCB rotor can easily last 250,000 to 300,000 km (155,000 to 186,000 mi), effectively outlasting the vehicle itself.
Ultra-Low Dust
Ultra-Low Visible Brake Dust. Heavy black dust destroying your wheel finish is a thing of the past. When paired with our matched StopFlex pads, these rotors generate virtually zero visible brake dust, keeping your premium wheels spotless for much longer.
Premium Visual Finish
Premium Mirror-Like Finish. StopFlex utilizes a patented ceramic formula that cures with a distinct crackle pattern. The surface is machined dead-smooth for high reflectivity, providing a premium aesthetic behind open wheels under the right lighting.
High Normal-Temp Friction
Strong Initial Bite (0.40μ+). With matched StopFlex pads, normal-temperature friction can exceed 0.40μ for a firmer pedal feel and strong initial bite.
Long-Fiber Construction
Continuous Long-Fiber Strength. StopFlex utilizes a continuous long-fiber 3D matrix. This structure is significantly stronger and offers higher thermal conductivity than standard chopped-fiber OEM CCM discs.
Cold First-Stop Confidence
Reliable Cold-Bite at -20°C (-4°F). Coated street rotors still deliver normal first-stop braking at -20°C (-4°F). Uncoated motorsport rotors are the exception.
Important heat note
Carbon ceramic does not shed heat as fast as steel. Long hard driving can heat-soak the rest of the brake system, including fluid, seals, and nearby parts. Unless the car already has strong brake cooling, or you plan to upgrade brake cooling, prolonged aggressive driving is not recommended.
Rotor options
Street Spec
Ceramic coating + cross-drilled face + large cooling channels.
345/320 is the sensible street choice for standard-brake Polestar 2 cars that want a straightforward daily-driven upgrade.
Track-Day Spec
Ceramic coating + blank face + honeycomb cooling channels.
375/340 suits Performance Pack cars or owners wanting more thermal headroom for repeated hard stops.
Motorsport Spec
No coating + blank face + honeycomb cooling channels. Not for normal street use.
Use the largest compatible 375 mm front-based setup when the car sees sustained high-speed laps or aggressive downhill work.

FAQ
Can I upgrade my Polestar 2 to a StopFlex carbon ceramic brake kit with the factory calipers, or do I need aftermarket calipers?
That depends on whether your car has the standard front brakes or the Performance Pack Brembo front calipers. Match the kit to your exact front caliper and rotor size first; if your car is non-Performance, confirm whether you are keeping the stock caliper package or converting to a larger caliper setup before ordering.
Which StopFlex carbon ceramic brake size is correct for my 2021-2026 Polestar 2?
Use 345 mm front and 320 mm rear for standard-brake cars, and 375 mm front with 340 mm rear for Performance Pack-based setups. The key buying step is identifying your current front brake package, because that is where Polestar 2 fitment usually changes.
Is a StopFlex carbon ceramic brake kit a good daily-driver upgrade for a Polestar 2, including cold first stops?
Yes, if you want a road-driven setup with better consistency and less heavy-EV brake punishment over time. Daily buyers should choose the street-oriented setup and order for their exact caliper package rather than over-sizing the kit just for appearance.
Will my Polestar 2 need extra cooling with a StopFlex carbon ceramic brake kit for repeated hard driving?
For normal road use, usually not. For repeated mountain descents or track sessions, the bigger concern is choosing the correct larger setup and making sure your wheel and airflow package are appropriate, because the Polestar 2’s mass can build heat quickly once friction braking takes over.
