Porsche Cayenne (9Y0) Turbo GT / Turbo E-Hybrid with GT Package Carbon Ceramic Brakes Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2022–2026 Porsche Cayenne (9Y0) Turbo GT / Turbo E-Hybrid with GT Package Carbon Ceramic Brake Kits
The 9Y0 Cayenne Turbo GT and Turbo E-Hybrid Coupe with GT Package are very heavy, very fast Porsche SUVs built around the 440mm front / 410mm rear PCCB layout. Factory references show 10-piston front and 4-piston rear fixed calipers, so buyers usually care about exact fitment, wheel clearance, and replacement cost control.
- Body style: Coupe
- Front rotor reference: Turbo GT/GT Package: 440mm(PCCB)
- Rear rotor reference: Turbo GT/GT Package: 410mm(PCCB)
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.
- Match the order to the 440mm front / 410mm rear GT/PCCB setup, not a standard Cayenne Turbo brake package.
- Confirm factory PCCB calipers, or provide full aftermarket caliper details before ordering.
- Best suited to owners replacing worn or damaged ceramic rotors without changing the character of the Turbo GT brake system.
- Heavy SUV use means heat and cooling matter more than on a lighter 911, especially for repeated high-speed braking.
- Track-day buyers should plan cooling, inspection intervals, and tire choice together, not treat rotors as the only upgrade.
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 uses long-fiber construction, which is stronger than the chopped-fiber CCM used in most OEM carbon-ceramic rotors.
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: choose this for daily driving, mountain roads, and factory-like usability.
Track-Day Spec
Ceramic coating + blank face + honeycomb cooling channels.
Trackday: choose this for repeated hard road use or occasional HPDE sessions with proper inspection habits.
Motorsport Spec
No coating + blank face + honeycomb cooling channels. Not for normal street use.
Motorsport: choose this only for sustained high-speed use with dedicated cooling and maintenance planning.

FAQ
Will a StopFlex carbon ceramic brake kit fit my Cayenne Turbo GT or Turbo E-Hybrid GT Package with the factory calipers?
Yes, order the kit for the factory 440mm / 410mm PCCB brake package with 10-piston front and 4-piston rear calipers. If your Cayenne has aftermarket calipers or brackets, confirm caliper model, rotor offset, and wheel clearance before ordering.
Which StopFlex CCB size should I select for this 9Y0 Cayenne Coupe row?
Select the Turbo GT / GT Package 440mm front and 410mm rear setup. Do not select a non-GT Cayenne Turbo size unless your car has been converted and measured.
Is the StopFlex CCB upgrade sensible for street use and cold first stops on this Cayenne?
For a daily-driven Turbo GT or Turbo E-Hybrid GT Package, choose the street-focused setup. It is the right direction if you want predictable first-stop behavior and low-drama road use rather than a heat-only track configuration.
Do I need extra cooling if I upgrade this Cayenne to a StopFlex CCB kit for hard use?
For aggressive road driving, the correct 440/410 setup and fresh supporting hardware may be enough. For prolonged track sessions in a nearly 5,000-lb SUV, plan brake cooling, cooldown laps, and frequent inspections before ordering the more aggressive rotor option.
