The build: parts and fitment
| Component | Configuration in this case | Why it's here |
|---|---|---|
| Vehicle | 2024+ Porsche Panamera (976) | Newer chassis with a forward-moved front brake package and common 21-inch wheel fitment |
| Front calipers | Gen 2 Akebono 10-piston | The 976-specific caliper that supports the larger 440 mm front rotor format |
| Front rotors | 440 mm STOPFLEX carbon ceramic | Pushes braking force further out for more leverage and a fuller look behind big wheels |
| Rear calipers | Factory 4-piston, retained | Keeps the existing rear brake architecture and EPB intact |
| Rear rotors | 410 mm STOPFLEX carbon ceramic | Matches the front in material so the car brakes as one coherent package |
| Pads | STOPFLEX ceramic pads | Very low dust, with normal-temperature friction that can exceed 0.4μ |
| Wheel requirement | 21-inch minimum | Needed for 440 mm front rotor and caliper barrel clearance |
Read this before you order
The older 971 front caliper will bolt up, but it caps you at the earlier 420 mm front rotor. If you specifically want the 440 mm front carbon ceramic setup on a 976, the Gen 2 Akebono caliper is the only correct route, and it requires 21-inch wheels.
Why this setup works on a 976
| STOPFLEX feature | Why it matters on the Panamera 976 | What you notice |
|---|---|---|
| 440 mm front carbon ceramic rotor | This is a big, fast executive sedan that asks a lot of its front axle, and the bigger rotor moves the contact patch outward for more leverage | A more substantial brake behind the spokes and a front end that doesn't feel under-braked at speed |
| Roughly half the weight of same-size steel | Heavy cars carry their brake mass at each corner, where it hurts ride and response most | Less rotating and unsprung mass, so the car feels a touch lighter on its feet |
| Low dust with STOPFLEX pads | 21-inch wheels show every speck of iron-pad dust, and nobody wants to scrub wheels weekly | Wheel faces that stay clean far longer between washes |
| No surface rust after rain | A daily-driven Panamera sits outside, and iron rotors flash orange fast | A clean rotor face through the spokes even after the car sits wet |
| Crackle-texture ceramic finish | On a car at this price point, the brake is part of the wheel's visual story | A finished, premium look that fills the 21-inch barrel properly |
What gets better
- A larger 440 mm front footprint sized for the car's mass and speed
- Less rotating and unsprung mass at each corner
- Dramatically less wheel dust when paired with STOPFLEX pads
- No orange rotor rust after the car sits in the rain
- A fuller, more premium look behind 21-inch wheels
What to confirm first
- Your car is the 976-generation Panamera, not the earlier 971
- You're running 21-inch wheels, or willing to move to them
- You want the Gen 2 Akebono front caliper, not a 971 carryover
- Front, rear, and pads are bought together as one package

FAQ
Can I use older 971-generation front calipers on my 976 Panamera?
They may bolt up physically, but they cap the front rotor at the older 420 mm format. If you want the 440 mm front carbon ceramic setup shown here, the correct match is the Gen 2 Akebono caliper designed for the 976 chassis.
Will this 440 mm front setup fit 20-inch wheels?
No. In this build the 440 mm front rotor and caliper position need 21-inch wheels for proper barrel clearance. If you have to keep 20-inch wheels, this exact front package is not the right match.
Do I need to reprogram the brake booster for the 10-piston front calipers?
No extra booster reprogramming was needed in this case. The 2024+ Panamera uses an electric brake booster, and the setup keeps the factory-style pedal behavior with a firm, linear response after installation.
How much weight do the carbon ceramic rotors save versus OEM iron?
STOPFLEX carbon ceramic rotors weigh roughly half of a same-size steel rotor. On a car as heavy as the Panamera 976, that takes real rotating and unsprung mass off each corner.
Will the carbon ceramic rotors rust if the car sits out in the rain?
No. STOPFLEX carbon ceramic rotors do not develop the orange surface corrosion that shows up on iron rotors after moisture, so the wheel face stays clean on a daily-driven 976.
