The 2024+ Porsche Panamera (976 Chassis) is more than just a facelift; it's a technical leap forward. While the suspension and powertrain have evolved, so have the brakes. But here is the secret most dealers won't tell you: The standard brakes still leave performance on the table. For the owner who demands Turbo S-level stopping power without the Turbo S price tag, we have engineered the ultimate OEM+ solution: The 976-Specific 10-Piston Carbon Ceramic Upgrade.
971 vs. 976: The Evolution of Braking
Porsche didn't just carry over the old parts. The new Panamera is faster and heavier, requiring more thermal capacity. Here is the breakdown:
| Chassis Generation | Front Caliper Spec | Max Rotor Size | Rear Rotor Size |
|---|---|---|---|
| Old (971) | Akebono 10-Piston (Gen 1) | 420mm | 410mm |
| New (976) | Akebono 10-Piston (Gen 2) | 440mm | 410mm |
The key takeaway? To get the proper "flush" look and maximum performance on a 2024+ model, you need the Gen 2 caliper and the 440mm rotor. Anything less is a compromise.
The 976 Build Spec (440mm)
This build utilizes the correct, chassis-specific hardware for the new Panamera.
| Vehicle | 2024+ Porsche Panamera (976) |
|---|---|
| Front Hardware | OEM 976-Spec 10-Piston + 440mm StopFlex CCB |
| Rear Hardware | OEM 4-Piston + 410mm StopFlex CCB |
| Wheel Req. | 21-inch Minimum (Standard on most 976 models) |
⚠️ Fitment Note
Because the front rotor has grown to 440mm, 21-inch wheels are now the mandatory minimum for this kit. The caliper is positioned further out radially to increase leverage (torque), meaning barrel clearance is tighter than on previous models.
The Rational Choice (Value Proposition)
Why choose StopFlex over factory PCCB? Simple math.
- Factory Option: Ticking the PCCB box on a new Panamera build sheet costs upwards of $10,000 USD (depending on region).
- StopFlex Retrofit: Our kit provides the exact same caliper hardware and carbon ceramic rotor technology for a fraction of the price.
You get the same 440mm visual impact, the same zero-dust benefits, and the same fade-free performance. It's the smart money choice for the informed Porsche owner.

2024 Panamera FAQ
Q: Can I use 971 (older) calipers on my 976?
Technically yes, they bolt up, but you will be limited to 420mm rotors. To get the proper 440mm rotor fitment that fills the 21-inch wheel arches correctly, you need the specific 976-generation calipers.
Q: Will this void my warranty?
This uses genuine OEM Porsche calipers. Mechanically, it is identical to a factory PCCB car. However, warranty coverage on the braking system itself (rotors/pads) will naturally shift to the StopFlex components.
Q: Do I need to change the brake booster?
No. The 2024 Panamera uses an electric brake booster (iBooster) that adapts to the hydraulic pressure requirements automatically. The pedal feel with the 10-piston calipers is firm and linear right out of the box.
