Confirm before you order
This is a custom big brake kit. The 420mm front and 410mm rear setup shown here generally needs 21-inch wheels to clear. A 20-inch fit may be possible with a different rotor package, but barrel and spoke clearance has to be checked against your exact wheel first.
What STOPFLEX CCB does for the Panamera 971
| STOPFLEX feature | Why it matters on a Panamera 971 | What you notice |
|---|---|---|
| Carbon ceramic rotors, about half the weight of steel | The 971 is a long, heavy four-door, so every kilo of rotating mass at the corners works the suspension hard. | Lighter turn-in, calmer body over expansion joints, and a car that feels smaller than its length. |
| Long-fiber CCB construction | Repeated hard stops from speed build heat fast on a car that can move like this one. | Pedal stays consistent down a long grade or after a hard highway pull instead of going soft. |
| High-heat friction stability | Surface friction holds near 0.3μ even at 900°C, and tops 0.4μ at normal temps with STOPFLEX pads. | Bite you can lean on whether the brakes are cold off the driveway or hot off a back road. |
| Low-dust STOPFLEX pads | Big 21-inch wheels show every bit of dust a steel system throws off. | Wheels stay clean far longer, so washing stops being a weekly chore. |
| Non-rusting friction surface | A daily-driven Panamera sees rain, car washes, and long parked stretches. | No rust bloom on the rotor face, plus a crackle-texture ceramic finish behind the spokes. |
| Long street life | Replacing premium iron hardware on a car this size adds up over the years. | Roughly 250,000 to 300,000 km of street life when the car stays off track. |
What gets better
- About 28 kg less unsprung and rotating mass for sharper response.
- Stable pedal feel under repeated hard stops, no early fade.
- Much lower brake dust on the 21-inch wheels.
- No rust staining on the rotor faces after rain or washing.
- Normal cold bite, with usable first-stop response even around -20°C.
- Long street life, roughly 250,000 to 300,000 km off track.
What to confirm first
- Your wheel diameter, since the 420F/410R layout generally wants 21-inch wheels.
- Barrel and spoke clearance against your exact wheel design before ordering.
- Current caliper and rotor hardware on your specific 971 trim.
- That you want a street-focused setup rather than a track-only build.
If you're not sure your car matches the spec shown here, send us your wheel and trim details and we'll confirm Porsche Panamera 971 fitment before you order through our Porsche CCB collection.

FAQ
Why pair Akebono front calipers with Brembo rear calipers on the Panamera 971?
This featured build runs a mixed-caliper layout matched front to rear. The Akebono 10-piston front calipers clamp 420mm STOPFLEX carbon ceramic rotors, while the rear uses Brembo 4-piston calipers on 410mm rotors for a balanced custom package on a heavy four-door.
Is this carbon ceramic setup fine for daily street driving?
Yes. It is built as a street-focused upgrade, not a track-only conversion. With the matched STOPFLEX pads you get clean operation, a stable pedal, and normal cold-weather bite, with usable first-stop response even around -20°C.
Will this Panamera 971 brake upgrade clear 20-inch wheels?
The 420mm front and 410mm rear package shown here generally needs 21-inch wheels for clearance. Some 20-inch fits may be possible with a different rotor size, but barrel and spoke clearance has to be confirmed against your exact wheel first.
Does the STOPFLEX carbon ceramic upgrade cut brake dust?
Yes. Paired with STOPFLEX pads, dust output is very low next to typical steel setups, so the wheels stay cleaner and you lose most of the dark residue large factory brakes leave behind.
How long do STOPFLEX carbon ceramic rotors last on a street Panamera?
On the street, with no track use, rotor life can reach roughly 250,000 to 300,000 km. Exact life depends on how you drive, pad choice, and conditions, but carbon ceramic rotors generally outlast steel in normal road use.
