Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2022-2026+ Cadillac CT4-V / Blackwing. Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| CT4-V Blackwing | 380mm | 340mm | 19" |
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
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.

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 CT4-V Blackwing with the factory Brembo calipers?
Yes. This kit is built for the 2022-2026+ CT4-V Blackwing with its 380mm front and 340mm rear factory iron rotors. It reuses your six-piston front and four-piston rear Brembo calipers, so we supply the carbon-ceramic discs, hats, floating hardware, and pads to bolt to what you already have. This page covers only the Blackwing trim and those exact rotor sizes — the standard CT4-V uses a different, smaller brake setup and is not covered here.
How do these brake in cold weather? I daily-drive mine through winter.
Straight physics: a cold carbon-ceramic disc bites less than cold iron on the very first stops. That's normal for the material, not a defect. We tuned both the pad compound and the disc's ceramic coating specifically for cold starts, so on the Blackwing your first-stop feel in winter now comes very close to summer feel. On the coldest mornings, leave a little extra following distance for the first few stops until the front 380mm discs are up to temperature — same habit that keeps you safe on any high-performance brake.
Why isn't factory carbon ceramic available for my car anyway?
Cadillac reserved the Brembo carbon-ceramic option for the CT5-V Blackwing. The CT4-V Blackwing shipped only with cast-iron discs behind its six-piston front and four-piston rear Brembos, so aftermarket is the only route to carbon ceramic on this car. This kit gives you that upgrade while keeping your existing calipers, master cylinder feel, and EPB behavior intact.
How much unsprung weight does this remove versus my iron rotors?
Carbon-ceramic discs run well under half the mass of the factory 380mm front and 340mm rear iron rotors, and the reduction is unsprung and rotating, so you feel it in steering response and ride over rough pavement. Track owners burning through iron discs also get a disc that resists the heat-cracking and fade that eats iron on repeated hard stops from the Blackwing's speeds. Pads are a carbon-ceramic-specific low-metallic resin compound with steel, copper, and aramid fiber, roughly 0.44 friction, stable to about 750 °C.
