Check this before you order
This kit is built around the factory fixed 10-piston front caliper. That's the one part that has to match. If your Sport Turismo runs a different factory front brake package, confirm fitment first — the rotor diameter is sized to that specific caliper.
What the upgrade does for this car
| STOPFLEX feature | Why it matters on a Sport Turismo | What you notice |
|---|---|---|
| 440mm front CCB rotor | This car is heavy and quick, and the factory 10-piston caliper was built for a big disc. The 440mm rotor gives it the full diameter and swept area it was meant to clamp. | Strong, repeatable bite on long descents instead of a pedal that goes soft once the brakes heat-soak. |
| Carbon ceramic vs. iron | A loaded wagon doing high-speed highway runs dumps a lot of heat into the rotors. Iron fades once it's saturated; ceramic holds its number. | Consistent pedal feel hard run after hard run. At 900°C, tested rotor friction still holds around 0.3μ. |
| About half the weight of steel | Rotors are unsprung and rotating mass. Cutting that at all four corners is weight the suspension no longer has to fight. | Sharper turn-in and a more settled ride over broken pavement. |
| Low-dust ceramic pads | Open-spoke 21 and 22-inch Porsche wheels show iron dust within a day or two of driving. | Wheels stay clean far longer, and the rotors don't rust after rain. |
| Long-fiber CCB construction | A daily-driven GT car needs a rotor that lasts, not a track-only consumable. | On the street, service life can run about 250,000–300,000 km. |
What gets better
- Heat-stable braking on mountain passes and long highway descents
- Lower unsprung mass for crisper steering and better ride compliance
- Very low brake dust on big open-spoke wheels
- Rotors that don't rust and look the part behind premium wheels
- Rear electronic parking brake works exactly as it did stock
What to confirm first
- Your car runs the factory fixed 10-piston front caliper
- Wheel fitment matches the 440mm front / 410mm rear sizing inside 21 or 22-inch wheels
- You want a direct-fit rotor swap rather than a full aftermarket caliper conversion
- Standard CCB pad bedding gets done at install
If you're not sure your car matches the spec shown here, send us your VIN and wheel details and we'll confirm Panamera Sport Turismo (976) fitment before you order through our Porsche CCB collection.

FAQ
Does this fit my Panamera Sport Turismo, or only certain ones?
This rotor upgrade is built for 976 Panamera Sport Turismo cars running the factory fixed 10-piston front caliper. If your car has that hardware, the 440mm front and 410mm rear STOPFLEX rotors bolt straight on. If you're running a different factory brake package, send us your details first and we'll confirm before you order.
Why a 440mm front rotor instead of something smaller?
The factory 10-piston caliper was engineered around a large rotor. A 440mm front disc gives that caliper the diameter and swept area it was designed to clamp, so you get the thermal capacity the hardware can actually use instead of undersizing it.
Is this a bolt-on, or do I need adapters and a full big brake kit?
Bolt-on. It replaces the factory rotors and keeps your original Porsche calipers and hydraulics. No adapter brackets, no caliper relocation, no lines to re-plumb.
Does the rear keep the electronic parking brake?
Yes. The rear 410mm setup retains the factory electronic parking brake function, so daily use is unchanged.
Will these stay clean behind my 21 or 22-inch wheels?
Paired with STOPFLEX pads, carbon ceramic rotors throw very little dust, so open-spoke 21 and 22-inch Porsche wheels stay clean far longer between washes. The rotors also don't rust after rain.
