Porsche Panamera (971) / 4 / 4S / 4 E-Hybrid / 4S E-Hybrid / GTS Carbon Ceramic Brakes Kit

2017–2023 Porsche Panamera (971) / 4 / 4S / 4 E-Hybrid / 4S E-Hybrid / GTS Carbon Ceramic Brake Kits The 971 Panamera is a fast, heavy grand-tourer offered as Sedan, Executive, and Sport Turismo, including hybrid variants. Brake sizing varies sharply across 360/330, GTS 390/365, and PSCB 410/380 setups, so ordering by trim alone is risky. Body style: Sedan, Executive & Sport Turismo Front rotor reference: Base/4/4S/Hybrid: 360mm; GTS: 390mm; PSCB option: 410mm Rear rotor reference: Base/4/4S/Hybrid: 330mm; GTS: 365mm; PSCB option: 380mm 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. Confirm current rotor diameter before ordering; 971 cars can have iron, GTS, PSCB, or prior retrofit hardware. Best match is for owners who want less unsprung mass, cleaner wheels, and more stable braking on repeated high-speed stops. Hybrid and Executive cars add weight, so heat margin matters more than peak stopping feel. GTS buyers should not assume base/4S sizing; the factory GTS package uses larger brakes. Sport Turismo owners who carry passengers or luggage should prioritize thermal capacity over appearance. 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. Use the direct confirmed size: 360/330 for Base/4/4S/Hybrid, 390/365 for GTS, or 410/380 only for PSCB-compatible hardware. Track-Day Spec Ceramic coating + blank face + honeycomb cooling channels. Choose the largest caliper-supported StopFlex setup you can verify, with suitable fluid and pre-event inspection. Motorsport Spec No coating + blank face + honeycomb cooling channels. Not for normal street use. Treat sustained lapping as a full brake system build: verified calipers, brackets, ducts, fluid, and temperature monitoring. Pads Item Details Pad shape The included StopFlex pad shape matches the OEM pad shape used by the retained caliper. Aftermarket calipers Provide the exact caliper model and StopFlex can supply the matching pad shape.

FAQ Will a StopFlex carbon ceramic brake kit fit my 2017–2023 Panamera 971 with factory calipers?It can be ordered for factory-caliper style fitment when the rotor diameter and caliper package are confirmed first. If the car has PSCB, PCCB, or aftermarket calipers, StopFlex should match the kit to photos, VIN/options, and measured rotor size before you order.Which StopFlex rotor size should I choose for my Panamera 4, 4S, Hybrid, or GTS?Most Base/4/4S/Hybrid cars use 360 mm front and 330 mm rear, while GTS uses 390 mm front and 365 mm rear. Cars with the PSCB option are different again at 410 mm front and 380 mm rear, so measure or verify the option code before checkout.Is a StopFlex CCB upgrade reasonable for daily street use on this Panamera, including cold first stops?Yes, if the kit is ordered with the intended street pad compound and the driver accepts a different feel than iron brakes. For daily use, the priority is predictable cold response, low noise, and clean operation rather than maximum track bite.Do I need extra cooling if I upgrade my Panamera 971 to StopFlex carbon ceramic brakes for hard driving?For fast road use, correct sizing, fluid condition, and pad choice may be enough. For prolonged sessions or repeated heavy stops in a heavy hybrid, Executive, or Sport Turismo, plan brake cooling and temperature checks before relying on the upgrade alone.
