The build: front and rear hardware
| Component | Specification |
|---|---|
| Vehicle | Porsche Panamera Sport Turismo (971) |
| Front calipers | OEM Akebono 10-piston Porsche calipers |
| Front rotors | 420 mm STOPFLEX carbon ceramic |
| Rear calipers | Factory 4-piston calipers retained |
| Rear rotors | 380 mm STOPFLEX carbon ceramic |
| Pads | STOPFLEX carbon-ceramic-specific compound |
| Wheel requirement | 21-inch wheels for front caliper clearance |
| Axle scope | Front PCCB-style conversion plus rear CCB rotor upgrade |
Check this before you order
The 10-piston, 420 mm front package needs 21-inch wheels, and even then barrel shape and spoke design have to clear the caliper. Don't assume any 21-inch wheel will fit — confirm your exact wheel against the caliper profile first.
Why carbon ceramic suits the Panamera 971
| STOPFLEX feature | Why it matters on the Panamera 971 | What you notice |
|---|---|---|
| Carbon ceramic rotors, ~half the weight of same-size steel | This is a long, heavy wagon, and the front axle carries most of the braking load | Less unsprung mass at each corner; the car feels more settled over rough pavement |
| Wide heat tolerance, ~0.3μ surface friction at 900°C | Repeated hard stops on a back road or a long grade push iron rotors into heat soak | Firm, predictable pedal that holds up as temperatures climb |
| Low dust with STOPFLEX pads, friction above 0.4μ at normal temps | 21-inch wheels show every bit of dust, and iron pads coat them fast | Wheels stay clean far longer between washes |
| Rotors that don't rust after rain | A daily-driven GT sits out in the weather and parks wet | No orange bloom on the rotor face after a rainy week |
| 420 mm front package with crackle-texture ceramic finish | The Panamera's scale wants a big, serious-looking brake behind the spokes | Cleaner, more premium look through 21-inch wheels |
What gets better
- More thermal headroom before the pedal goes soft
- Lighter rotors trim unsprung and rotating mass
- Brake dust drops sharply with the matched pads
- Rotor faces stay clean and rust-free after wet weather
- Factory rear calipers keep brake bias and the EPB working as designed
What to confirm first
- 21-inch wheels are required for the front package
- Wheel barrel shape and spoke design must clear the caliper
- Decide between rotor-only and the full 10-piston front conversion
- Run the carbon-ceramic-specific pads to get the low-dust benefit
- Keep the rear on the factory 4-piston calipers with 380 mm rotors

FAQ
Can you retrofit PCCB-style carbon ceramic brakes on a Panamera Sport Turismo 971?
Yes. This build runs OEM Akebono 10-piston front calipers with 420 mm STOPFLEX carbon ceramic rotors up front and 380 mm STOPFLEX rotors on the factory rear calipers, a proven PCCB-style path for the Panamera Sport Turismo 971.
Why keep the factory rear calipers on the Panamera 971?
Keeping the factory 4-piston rear calipers preserves the original front-to-rear brake balance and leaves the electronic parking brake working as designed, with no added wiring or adapter complexity.
What wheel size does the 10-piston 420 mm front package need?
This front package requires 21-inch wheels for clearance. Even on 21s, barrel shape and spoke design should be checked against the caliper profile before you order.
What will I actually notice after the STOPFLEX carbon ceramic upgrade?
Stronger resistance to heat soak on long drives, lighter rotors at about half the weight of same-size steel, far less brake dust with STOPFLEX pads, rotor faces that do not rust after rain, and a cleaner look behind 21-inch wheels.
