Will This Fit My Car?
Direct Replacement CCB Discs (Retain Factory Calipers) for the 2019-2020 Cadillac CT6-V. Factory rotor specifications and the smallest wheel that clears each trim:
| Trim | Front Rotor (Factory) | Rear Rotor (Factory) | Min. Wheel Size |
|---|---|---|---|
| CT6-V | 390mm | 345mm | 20" |
Keep Your Factory Calipers?
Keep them if the front calipers are fixed 4-piston or more — the rear axle qualifies regardless. Front 1- or 2-piston floating calipers rule out the disc-only route; choose the Full Upgrade kit instead. Every set is machined to the factory rotor specs listed above, and aftermarket calipers (Brembo, AP Racing, Alcon, Wilwood) only need the caliper model, pad shape, and rotor dimensions confirmed before we build.
Spoke profile and offset also affect clearance — confirm your exact wheels before ordering.

Why Carbon Ceramic — and Why StopFlex
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.
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.
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
High rotor temperature tolerance does not mean heat management disappears. Under repeated hard braking, heat migrates into the pads, brake fluid, seals, calipers, and wheels even when the ceramic disc itself is comfortable. Plan brake cooling and high-temperature fluid for extended track sessions, long mountain descents, or sustained aggressive driving.
Get Your Fitment Confirmed
Send the exact vehicle details, current rotor sizes, and caliper type before ordering. Every StopFlex order is confirmed against your VIN-level configuration before production.
FAQ
Will this fit my exact CT6-V, and does it work with the electronic parking brake?
This page covers the 2019-2020 CT6-V only, with the factory 390mm front and 345mm rear rotor sizes. It's a direct replacement that reuses your factory Brembo calipers, including the integrated rear electronic parking brake mechanism, so the EPB continues to function normally. Confirm your front calipers are the original 4-piston (or larger) units before ordering, since direct replacement requires that front piston count.
How do these carbon ceramic rotors behave in winter and on cold mornings?
Any cold carbon-ceramic disc bites a little less than cold iron on the first stop of the day. That's physics, not a defect. We tuned both the pad compound and the disc's ceramic surface coating for cold starts, so cold-car feel on the CT6-V now comes very close to warm summer feel after the first rotation or two. On the coldest first stops, leave a little extra following distance until the front 390mm rotors come up to temperature.
Why is this so much less than the dealer replacement CCB rotors?
CT6-V owners see quotes north of $4,000 per corner for factory carbon-ceramic rotors. This kit gives you carbon-ceramic front (390mm) and rear (345mm) discs, matched pads, hats, and floating hardware while keeping your original calipers, which is the single biggest cost driver on a factory replacement. You get the heat and weight benefits of CCB without buying an entire big-brake system.
What pads come with the kit and how much heat can they take?
The kit includes a carbon-ceramic-specific low-metallic resin-composite pad built with steel, copper, and aramid fiber. Average friction coefficient is about 0.44, with heat resistance to roughly 750 °C and strong anti-fade behavior, which suits the CT6-V's 587 hp Blackwing V8 on both street and track-day duty. The pad is matched to the disc coating, so don't swap in a generic iron-rotor pad.
