2019-2020 Cadillac CT6-V Carbon Ceramic Brake Kit — OEM-Size Replacement
The 2019-2020 Cadillac CT6-V puts 550 hp through a 4,470-lb AWD sedan, so repeated high-speed stops can overwhelm conventional iron rotors with heat, pad transfer, dust, and steering shake. This StopFlex OEM-size carbon-ceramic replacement kit is built around the CT6-V brake references: 390 mm front rotors and 345 mm rear rotors, with matched pads, hats, and floating hardware for the factory caliper package. The payoff is lower rotating mass, higher heat stability, cleaner open 20-inch wheels, and fitment tied to the exact CT6-V rotor sizes listed here.
- Sized for the CT6-V brake package only: 390 mm front rotors and 345 mm rear rotors, not the 345 mm heavy-duty front brake setup used on other CT6 configurations.
- Includes carbon-ceramic rotors, matched pads, hats, and floating hardware so the rotor assembly replaces the OEM-size friction package rather than changing caliper position.
- Built for the 2019-2020 CT6-V Blackwing twin-turbo V8 AWD sedan, where curb weight, speed, and 20-inch open wheels make heat control, brake dust, and unsprung weight visible concerns.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Cadillac CT6-V |
| Model years | 2019-2020 |
| Front rotor reference | CT6-V: 390mm |
| Rear rotor reference | CT6-V: 345mm |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 20" (for the 390 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 390 mm rotor, so the minimum wheel size is 20". Wheels under 20" 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 2019-2020 Cadillac CT6?
No. This page is limited to the 2019-2020 Cadillac CT6-V brake setup with 390 mm front rotors and 345 mm rear rotors. Other CT6 trims can use different brake codes and rotor diameters, including 345 mm front heavy-duty iron rotors, so those cars must not be ordered from this page.
Will my factory wheels and calipers still fit?
This is an OEM-size replacement for the CT6-V rotor package, so it is intended to work with the factory CT6-V calipers and the wheel clearance used for the 390 mm front brake assembly. Confirm your car has the listed CT6-V rotor sizes before ordering, especially if the car has aftermarket wheels or a prior brake conversion.
Does the electronic parking brake and auto-hold system still work?
The kit replaces the rotors, pads, hats, and floating hardware while retaining the vehicle-side brake controls. On a correctly configured CT6-V, the electronic parking brake and auto-hold functions remain governed by the factory rear brake hardware and control system, not by a standalone aftermarket parking brake.
Why switch a CT6-V from iron rotors to carbon ceramic?
Carbon-ceramic rotors reduce rotating and unsprung mass and hold friction behavior more consistently under repeated heat cycles. On a CT6-V, that matters because the car combines a 4.2L twin-turbo V8, AWD traction, and large sedan weight with visible 20-inch wheels that show iron brake dust quickly.
