Rolls-Royce Ghost (RR21) Black Badge / Extended / Ghost Carbon Ceramic Brakes Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2021-2026 Rolls-Royce Ghost (RR21) Black Badge / Extended / Ghost Carbon Ceramic Brake Kits
The RR21 Ghost is a very heavy luxury sedan that still sees fast-road use, especially in Black Badge form. Buyers usually want a cleaner wheel appearance, less brake dust, and stronger heat margin without upsetting the car’s factory refinement.
- Body style: Sedan
- Front rotor reference: Ghost (RR21): 395mm
- Rear rotor reference: Ghost (RR21): 370mm
This is an OEM-size replacement kit. The rotors are built to the factory rotor spec and install with the factory caliper when the front caliper is a fixed design and the rotor spec matches. The included pad shape matches the OEM pad shape. If the car uses aftermarket calipers such as Brembo, AP Racing, Alcon, or Wilwood, provide the exact caliper model and StopFlex can supply the matching pad shape. Direct replacement is not confirmed if the front caliper is floating, or if the car already runs a non-OEM-offset rotor and the actual rotor dimensions cannot be supplied.
Why StopFlex CCB
Lightweight
Half the Weight, Sharper Handling. StopFlex carbon-ceramic rotors shed roughly half the mass of equivalent iron discs. This massive drop in unsprung weight instantly transforms your chassis, delivering sharper turn-in response and a significantly more refined road feel.
High-Temp Resistance
Minimal Brake Fade at 900°C (1652°F). While traditional iron rotors severely fade under heavy track loads, our CCB matrix holds a stable 0.30μ friction coefficient even at 900°C (1652°F). You get consistent, predictable stopping power when things get dangerously hot.
Corrosion Resistance
100% Rust-Free Durability. Say goodbye to flash rust after a car wash or heavy rain. The carbon-silicon carbide material is naturally impervious to corrosion, ensuring your brake rotors look completely clean and pristine no matter the weather conditions.
Long Lifespan
250,000+ km (155,000+ mi) Lifespan. Iron rotors typically require replacement around 100,000 km (62,000 mi). In normal street driving conditions, a StopFlex CCB rotor can easily last 250,000 to 300,000 km (155,000 to 186,000 mi), effectively outlasting the vehicle itself.
Ultra-Low Dust
Ultra-Low Visible Brake Dust. Heavy black dust destroying your wheel finish is a thing of the past. When paired with our matched StopFlex pads, these rotors generate virtually zero visible brake dust, keeping your premium wheels spotless for much longer.
Premium Visual Finish
Premium Mirror-Like Finish. StopFlex utilizes a patented ceramic formula that cures with a distinct crackle pattern. The surface is machined dead-smooth for high reflectivity, providing a premium aesthetic behind open wheels under the right lighting.
High Normal-Temp Friction
Strong Initial Bite (0.40μ+). With matched StopFlex pads, normal-temperature friction can exceed 0.40μ for a firmer pedal feel and strong initial bite.
Long-Fiber Construction
Continuous Long-Fiber Strength. StopFlex utilizes a continuous long-fiber 3D matrix. This structure is significantly stronger and offers higher thermal conductivity than standard chopped-fiber OEM CCM discs.
Cold First-Stop Confidence
Reliable Cold-Bite at -20°C (-4°F). Coated street rotors still deliver normal first-stop braking at -20°C (-4°F). Uncoated motorsport rotors are the exception.
Important heat note
Carbon ceramic does not shed heat as fast as steel. Long hard driving can heat-soak the rest of the brake system, including fluid, seals, and nearby parts. Unless the car already has strong brake cooling, or you plan to upgrade brake cooling, prolonged aggressive driving is not recommended.
Rotor options
Street Spec
Ceramic coating + cross-drilled face + large cooling channels.
Street spec is the right match for most RR21 Ghosts that stay daily driven and comfort-focused.
Track-Day Spec
Ceramic coating + blank face + honeycomb cooling channels.
Trackday spec suits faster Black Badge or chauffeur-light cars that see repeated hard road use and want more heat margin.
Motorsport Spec
No coating + blank face + honeycomb cooling channels. Not for normal street use.
Motorsport spec should be chosen only for unusually aggressive use, with brake cooling and system heat management considered at the same time.

FAQ
Will a StopFlex carbon ceramic brake kit for the Rolls-Royce Ghost RR21 work with my factory calipers, or do I need aftermarket calipers?
For this RR21 row, the intended setup is the OEM iron-brake car with the factory calipers retained. You should confirm exact rotor and caliper pairing before order, because caliper compatibility is the key fitment checkpoint on this platform.
What is the correct StopFlex size/setup for my 2021-2026 Rolls-Royce Ghost RR21, Ghost Extended, or Black Badge?
For this exact vehicle row, the matched sizes are 395mm front and 370mm rear. Most buyers should stay with the stock-diameter RR21 setup and choose the rotor spec by use case rather than trying to oversize the package.
Is a StopFlex carbon ceramic brake kit on the Rolls-Royce Ghost RR21 still suitable for street use, cold starts, and normal daily driving?
Yes, if your Ghost is mainly a road car, the street-focused setup is the safer choice. It keeps the upgrade aligned with daily-use manners, which matters more on an RR21 than chasing a harsher track-biased feel.
Do I need extra cooling if I upgrade my Rolls-Royce Ghost RR21 to a StopFlex carbon ceramic brake kit for prolonged hard use?
If the car will see repeated heavy stops, long descents, or sustained high-speed driving, cooling and fluid condition deserve attention. Carbon ceramic helps with heat tolerance, but a heavy RR21 can still load the whole brake system hard during prolonged use.
