Confirm before you order
This is built for Panamera 976 cars running the factory 10-piston Akebono front calipers. It's a rotor-only conversion around those calipers, not a universal swap. Check your exact model year, brake package, and wheel spec before ordering.
Why Carbon Ceramic Changes This Car
| STOPFLEX feature | Why it matters on the Panamera 976 | What you notice |
|---|---|---|
| Carbon ceramic rotor, about half the weight of same-size iron | The Panamera is heavy and quick, and the iron disc is the single biggest chunk of weight spinning at each corner. Drop it and you drop both unsprung and rotating mass. | Lighter steering over broken pavement and a car that settles faster after a bump. |
| Holds about 0.3μ friction at 900°C | Big-car speed dumps a lot of heat into the rotor. Iron starts fading once it's heat-soaked; carbon ceramic keeps biting. | A pedal that stays firm on a long highway descent or back-to-back stops instead of going long. |
| Over 0.4μ at normal temps, normal first stop near -20°C | A street car has to stop hard on the first pedal press, cold, not after a warm-up lap. | Strong, predictable bite from the first stop on a cold morning. |
| Very low dust with STOPFLEX pads | Iron rotors with sharp pads coat 21-inch wheels in black dust, which fights the whole point of a clean luxury car. | Wheels that stay clean far longer between washes. |
| Rotor face doesn't rust, long-fiber construction | Iron discs flash-rust after rain or a wash and show it through open spokes; the long-fiber build is there for structural strength. | A clean rotor face behind the spokes year-round, plus the crackle-texture ceramic finish. |
What gets better
- Less unsprung and rotating mass at every corner
- Firm pedal that resists fade on long descents and repeated stops
- Strong cold bite from the very first press
- Far less brake dust on the wheels
- No flash-rust on the rotor face after rain
- Street life rated around 250,000 to 300,000 km untracked
What to confirm first
- That your car runs the factory 10-piston Akebono front calipers
- Your exact model year and brake package
- OEM 21-inch wheel clearance against your specific wheels
- Rear electronic parking brake requirements
- Front and rear rotor sizes match this application (440mm / 410mm)

FAQ
My factory 10-piston calipers are strong. Why bother changing the rotors?
The calipers aren't the weak link on a Panamera. The heavy iron rotors are. They add rotating and unsprung mass and they heat-soak under repeated hard stops, which is where pedal feel goes soft. A carbon ceramic rotor cuts that weight and holds its friction far better when things get hot, so the calipers you already have work better.
Is this a big brake kit or just a rotor swap?
It's a direct-fit rotor conversion. You keep the factory 10-piston Akebono front calipers and the rear calipers, and replace the iron discs with STOPFLEX carbon ceramic rotors plus the matching pad compound. No aftermarket caliper, no relocation brackets.
Will it clear my OEM 21-inch wheels?
The conversion is built around the factory brake dimensions, so it's designed to clear the OEM 21-inch wheel package on the car shown here. Always confirm against your exact wheel and vehicle spec before ordering.
How does this compare to factory PCCB for daily driving?
In daily use the benefits line up: very low brake dust, strong heat tolerance, no rust on the rotor face, and a real drop in unsprung weight versus iron. The difference is this keeps your original calipers, so you get carbon ceramic behavior without a full factory PCCB retrofit.
How long do the rotors last on the street?
For street use STOPFLEX rates rotor life at roughly 250,000 to 300,000 km when the car isn't tracked. Your real number depends on driving style, pad choice, and conditions.
Does the rear keep the electronic parking brake?
Yes. The rear rotor hat is designed to retain full electronic parking brake function. Confirm fitment against your exact vehicle spec before ordering.
