The Perfect Match: A 440mm STOPFLEX Carbon-Ceramic Upgrade for the Panamera Sport Turismo
The Porsche Panamera Sport Turismo (976) is the ultimate fusion of performance and practicality, featuring some of Porsche's most advanced engineering—including formidable factory 10-piston front calipers. This case study details the installation of the **STOPFLEX 440mm Carbon-Ceramic Rotor System**, a solution purpose-built to be the perfect match for this elite factory hardware.
The OEM-Spec 440mm Rotor System
This is a complete, bolt-on upgrade that provides the 440mm front and 410mm rear rotors that the 976 chassis's top-tier calipers were designed for, delivering a no-compromise, perfectly integrated solution.
- Vehicle: Porsche Panamera Sport Turismo (976)
- Front Rotors: STOPFLEX 440mm Carbon-Ceramic Discs with custom-fit billet aluminum hats
- Rear Rotors: STOPFLEX 410mm Carbon-Ceramic Discs with custom-fit billet aluminum hats
- Brake Pads: STOPFLEX Performance Pads formulated for Carbon-Ceramic
- Brake Lines: STOPFLEX Stainless Steel Braided Lines
Fitment Requirements for STOPFLEX Rotors
This direct-fit upgrade is possible because the Panamera 976 is equipped with elite factory hardware that meets our two critical conditions:
- Caliper Type: The factory calipers are the required opposed multi-piston (fixed) design.
- Minimum Size: The factory system is designed for massive rotors, well above our 355mm minimum.
Key Advantages for the Panamera 976 Platform
Our purpose-built system is more than an upgrade; it's a meticulously engineered solution that completes the vehicle's performance potential.
- Engineered for Porsche’s 10-Piston Calipers: The 976 chassis introduced incredible 10-piston front calipers designed for 440mm rotors. Our system provides these exact OEM-spec 440mm carbon-ceramic discs, offering a perfect, no-compromise fit **without the hassle of retrofitting parts from other models like the Cayenne.**
- Proportional Performance for Large Wheels: For owners running 21" or 22" wheels, the larger 440mm rotor not only looks proportionally correct, but it also provides the necessary increase in thermal mass and braking leverage to effectively manage the heavier wheel and tire package.
- An Intelligent Alternative to Factory Carbon (PCCB): The factory Porsche Carbon Ceramic Brake (PCCB) option is an investment that can exceed RMB 100,000 in the Taiwan market. Our system is engineered to deliver the same elite level of performance—fade-proof stopping, massive weight reduction, and zero dust—at a more accessible price point.
- Enhanced Driving Dynamics: Our carbon-ceramic discs are **up to 50% lighter than factory iron rotors**. By reducing this critical unsprung mass at all four corners, the Panamera's celebrated handling becomes even more responsive and the ride more composed.

Frequently Asked Questions for Panamera 976 Owners
Q: Why is a 440mm rotor better than the 420mm rotor on some Panamera models?
A: The factory 10-piston caliper is physically designed to work most effectively with a 440mm rotor, providing the maximum pad contact patch and braking leverage. For vehicles with larger, heavier 21" or 22" wheels, the 440mm rotor also offers greater thermal capacity to prevent fade and provides a more balanced and proportional aesthetic.
Q: Is this installation complicated?
A: No. A key benefit of our system is its **100% direct-fit** design. It is a bolt-on replacement for the factory rotors and requires no adapters or modifications. This preserves the Panamera's original engineering geometry and simplifies the installation process for a qualified technician.
Q: How does the performance feel compared to the stock iron brakes?
A: Drivers report a more immediate and confident pedal feel. The car feels more agile due to the significant reduction in unsprung mass. Most importantly, the braking is consistently powerful and fade-free, even under hard, repeated use, which fully complements the Panamera's "sports car in disguise" character.
