Check this before you order
This kit is built for Panamera (976) cars running the factory fixed multi-piston brake package. It replaces the iron rotors and reuses your existing calipers, so confirm your car's exact brake setup matches before buying.
What the upgrade actually does
| STOPFLEX feature | Why it matters on a Panamera 976 | What you notice |
|---|---|---|
| Carbon ceramic rotors, about half the weight of steel | The Panamera is a big, heavy four-door, so every kilo at the wheel hurts ride and steering. This build cuts roughly 20 kg total. | Sharper turn-in and a car that feels less like it's dragging mass over bumps. |
| Holds ~0.3μ surface friction at 900°C | A fast, heavy sedan dumps a lot of heat into the brakes on a long descent or a back-road blast. | A firmer, more repeatable pedal after several hard stops instead of fade. |
| Low-dust ceramic pads | Big multi-spoke Porsche wheels show every speck of brake dust and are a pain to keep clean. | Wheels that stay clean far longer between washes. |
| Rotors don't rust after rain | Steel discs build an orange film overnight and feel rough on the first few stops. | No surface rust, no gritty first-brake feel after the car sits. |
| Long-fiber CCB construction | A high-value car like this gets driven for years, so rotor durability is part of the math. | Street life that can reach roughly 250,000–300,000 km with no track use. |
What gets better
- Around 20 kg less unsprung mass for crisper steering and better composure over rough roads
- Stronger fade resistance when you're braking hard and often
- Much cleaner wheels thanks to low-dust pads
- No rust film after rain, so first-stop feel stays consistent
- Long street life on a car you plan to keep
What to confirm first
- Your Panamera 976 runs the factory fixed multi-piston brake package
- Front 440 mm and rear 410 mm rotor sizing matches your car
- You're keeping the factory calipers, not doing a big brake conversion
- Your wheels are OEM 21-inch or otherwise clear the rotors
If you're not sure your car matches the spec shown here, send us your details and we'll confirm Porsche Panamera 976 fitment before you order through our Porsche CCB collection.

FAQ
Do I have to swap the factory Porsche calipers?
No. This is a rotor-only upgrade for Panamera 976 cars running the factory fixed multi-piston brake package. The STOPFLEX carbon ceramic discs are built to bolt to your original calipers, so there's no full big brake conversion involved.
Will these rotors clear factory 21-inch wheels?
Yes. This build uses 440 mm front and 410 mm rear rotors sized to the factory brake package, with fitment confirmed for OEM 21-inch wheels. Always verify against your exact car before ordering.
How do carbon ceramic brakes behave when they're cold or wet?
You may notice a slightly different initial bite on the first stop when the discs are cold or wet. Paired with STOPFLEX pads, cold-weather response stays normal for street use, so the car is fine as a daily driver.
How is this different from factory PCCB?
It gets you carbon ceramic rotor performance while keeping your factory calipers. If you want lower rotor weight, strong heat resistance, and clean wheels without replacing the whole brake system, this is the OEM-style path to it.
How long do the rotors last on the street?
For street driving with no track use, STOPFLEX rotor life can reach roughly 250,000 to 300,000 km, far longer than a typical steel rotor under the same conditions.
