2021-2026+ Polestar 2 Carbon Ceramic Brake Kit — OEM-Size Replacement
The Polestar 2 is heavy, quick, and regen-heavy, so owners shopping this OEM-size carbon-ceramic kit are usually trying to reduce iron rotor heat, corrosion, brake dust, and rotating mass without changing the factory brake package. StopFlex builds this page around the two Polestar 2 brake families: Performance Pack 375 mm front / 340 mm rear and standard 345 mm front / 320 mm rear. The kit includes carbon-ceramic rotors, matched pads, hats, and floating hardware for the listed rotor size so the buyer can keep the correct factory caliper architecture while gaining carbon-ceramic thermal stability and cleaner wheels.
- Performance Pack fitment is based on the 375 mm front rotor used with the Polestar 2’s Swedish-gold four-piston Brembo front calipers and 340 mm rear rotor.
- Standard Polestar 2 fitment on this page is limited to the 345 mm front and 320 mm rear OEM-size rotor package; Performance Pack and standard parts are not interchangeable.
- Carbon-ceramic rotors reduce brake dust and rotating mass versus iron discs, a direct benefit on a high-curb-weight EV with open 19- or 20-inch wheel designs.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Polestar 2 |
| Model years | 2021-2026+ |
| Front rotor reference | Perf: 375mm; Std: 345mm |
| Rear rotor reference | Perf: 340mm; Std: 320mm |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 19" (for the 375 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 375 mm rotor, so the minimum wheel size is 19". Wheels under 19" 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 kit fit every 2021-2026+ Polestar 2?
No. This page is limited to the exact brake setup selected at order: Performance Pack 375 mm front / 340 mm rear or standard 345 mm front / 320 mm rear. Confirm your rotor diameters, caliper type, model year, and wheel clearance before ordering.
Does the kit keep the factory parking brake and auto-hold functions?
The kit is designed as an OEM-size rotor and pad replacement for the listed Polestar 2 brake package, so the factory rear brake control strategy is retained when the correct rear fitment is supplied. Confirm the rear rotor size and EPB configuration before production.
Why switch a Polestar 2 from iron rotors to carbon-ceramic rotors?
Carbon-ceramic rotors are chosen for lower dust, lower rotating mass, and more stable friction behavior under repeated high-energy stops. On a Polestar 2, those gains matter because the car is EV-heavy and can mask brake wear during regen-heavy daily driving until the friction brakes are pushed hard.
What should I verify before placing the order?
Verify whether the car has Performance Pack Brembo front calipers or the standard caliper package, measure or confirm the front and rear rotor diameters, and confirm the wheels clear the selected brake package. The 375 mm Performance Pack setup requires the correct wheel clearance; do not assume standard Polestar 2 wheels fit it.
Need Fitment Confirmation?
Send the exact vehicle details, current rotor sizes, and caliper type before ordering.
