Official Warranty: We offer a 1-year free replacement for quality defects or coating issues under normal (non-track) use. Please note that provided specs apply strictly to brake hats and brackets; wheel fitment data is for general reference only. Wheel clearance issues are excluded from warranty coverage and data accuracy claims. If additional clearance is needed, wheel spacers must be added at the customer's discretion.

Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2021-2026+ Polestar 2. Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| Perf | 375mm | 340mm | 19" |
| Std | 345mm | 320mm | 18" |
Keep Your Factory Calipers?
Front factory calipers must be fixed 4-piston or more; the rear axle is unrestricted. A 1- or 2-piston floating front setup belongs on the Full Upgrade route rather than this disc-only listing. For aftermarket calipers such as Brembo, AP Racing, Alcon or Wilwood, send the exact caliper model, pad shape, rotor dimensions and offset for custom-fitment review before ordering.
Spoke profile and offset also affect clearance — confirm your exact wheels before ordering.

Why Carbon Ceramic — and Why StopFlex
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.
Short-Fiber or Long-Fiber — Your Call
Every StopFlex disc is true carbon-ceramic. Short-Fiber Street Spec uses a simpler chopped-fiber process for a lower price and street-only duty; the Long-Fiber line uses continuous carbon strands that carry load across the whole rotor for higher strength and thermal durability — the pick for track and race heat.
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 like-size carbon-ceramic rotor can be materially lighter than an iron disc; the exact saving depends on rotor dimensions. Lower rotating, unsprung mass can reduce the load the suspension has to control.
High-Temperature Stability
The carbon-silicon-carbide friction material is selected for high-temperature stability and fade resistance. Overall pedal feel still depends on pad condition, fluid, caliper stiffness, cooling and operating temperature.
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, carbon-ceramic friction surfaces are designed for low wear. Actual service life depends on mileage, contamination, pad choice, heat cycles and driving use.
Low Visible Dust
Matched StopFlex pads are selected for low visible dust on the ceramic friction surface. Actual wheel dust still varies with pad choice, traffic, temperature, bedding and driving intensity.
Winter & Cold-Weather Braking
Cold-weather trade-off: an untuned carbon-ceramic disc can have less initial bite than cold iron. StopFlex specifies a matched pad compound and ceramic coating tuned to reduce that cold-start gap, but the coldest first stops still deserve extra following distance. Severe-winter daily drivers should choose a Street Spec.
Choose Your Rotor: Short-Fiber Street to Long-Fiber Motorsport
Pick by how you drive and what you want to spend. Street-only and budget-minded: Short-Fiber Street Spec. Premium street, track days, or competition: one of the three Long-Fiber specs, whose continuous carbon strands carry the strength and heat margin that repeated hard braking demands.
Short-Fiber Street Spec
Chopped short-fiber carbon-ceramic body, ceramic coating, cross-drilled face.
Choose this for street-only use when purchase price matters most. It keeps the carbon-ceramic friction surface and coated finish, but it is not specified for track sessions.
Long-Fiber Street Spec
Continuous long-fiber body, ceramic coating, cross-drilled face, large cooling channels.
Choose this for daily and fast-road use when you want the long-fiber construction without moving to a track-focused face and cooling specification.
Long-Fiber Track-Day Spec
Continuous long-fiber body, ceramic coating, blank face, honeycomb cooling channels.
Choose this for repeated fast-road or track-day braking where thermal duty matters more than the drilled street appearance. High-temperature fluid and appropriate cooling still matter.
Long-Fiber Motorsport Spec
Continuous long-fiber body, uncoated blank face, honeycomb cooling channels.
Choose this for competition-focused use with the corresponding pad, fluid, cooling and warm-up strategy. It is not the default recommendation for a street-driven car.
Heat Management Note
Ceramic discs shrug off surface temperatures that would destroy iron, but the rest of the system still heats up: pads, fluid, seals, calipers, and wheels all absorb soak heat during repeated hard stops. For track days, long descents, and sustained hard driving, run brake cooling and high-temperature fluid.
Get Your Fitment Confirmed
Send the exact year, model, trim, current rotor sizes, caliper type, and wheel details before ordering. StopFlex confirms the supplied configuration before production and requests VIN/build data when needed.
FAQ
Which Polestar 2 brake configurations does this Direct Replacement set cover?
This listing covers 2021-2026+ Polestar 2 configurations using the supplied factory rotor references: 375 mm Performance or 345 mm Standard front discs, plus 340 mm Performance or 320 mm Standard rear discs. The front factory calipers must be fixed 4-piston or larger; the rear axle has no caliper restriction.
Do I keep my factory calipers with these carbon-ceramic discs?
Yes. This is a Direct Replacement configuration that retains the factory calipers. The package uses StopFlex CCB rotors, matched pads, vehicle-specific rotor hats and floating hardware for the applicable Polestar 2 rotor reference.
Which StopFlex rotor specification should I choose for my Polestar 2?
Choose Short-Fiber Street Spec for the lower-cost, street-only option. Long-Fiber Street, Track-Day and Motorsport use long-fiber construction for progressively higher heat and duty requirements. Select the specification around the vehicle’s actual use, then confirm the 375/345 mm front and 340/320 mm rear configuration before ordering.
How do these brakes behave on cold winter starts?
An untuned cold carbon-ceramic disc can have less initial bite than cold iron. StopFlex specifies a matched pad compound and disc coating to reduce that cold-start gap, but the coldest first stops still deserve extra margin. Allow normal braking distance until the system has some temperature.
