The build: 992 CCB hardware and parts
| Item | STOPFLEX 992 configuration | Notes |
|---|---|---|
| Vehicle | Porsche 911, 992 chassis (Carrera-based) | Retrofit path for cars without factory PCCB |
| Front package | OEM-style Porsche PCCB caliper with 420 mm STOPFLEX carbon ceramic rotor | Larger front package; wheel clearance must be confirmed |
| Rear package | OEM-style rear caliper with 390 mm STOPFLEX carbon ceramic rotor | Keeps front-to-rear balance honest under repeated stops |
| Rotor construction | STOPFLEX long-fiber carbon ceramic | About half the weight of a same-size steel rotor |
| Wheel fitted in this build | 20-inch front / 21-inch rear | Diameter alone does not guarantee caliper clearance |
| Unsprung weight change | About 18 kg (roughly 40 lb) lighter vs iron | Build-specific figure for this setup |
Confirm before you order: the 420 mm front rotor and larger caliper leave very little margin inside the wheel. A 20-inch front is the starting point, not a guarantee — spoke shape, offset, and inner barrel profile all need checking, especially on aftermarket wheels.
Why carbon ceramic on a 992
| STOPFLEX feature | Why it matters on a 992 | What you notice |
|---|---|---|
| Rotor about half the weight of steel | A 911 lives or dies on how it changes direction; weight at the corners blunts that | Roughly 18 kg less unsprung mass, crisper turn-in and ride response |
| Long-fiber carbon ceramic construction | Street and fast back-road use means repeated hard stops, not one big one | Pedal stays consistent stop after stop instead of going long with heat |
| High-heat friction holds ~0.3μ at 900°C | A long mountain descent stacks heat into the system fast | The brakes still bite when an iron setup would start fading |
| Low dust with STOPFLEX pads | 992 wheels are open-spoke, so the calipers and rotors are on display | Wheel faces stay clean; less scrubbing between washes |
| No rust after rain | A daily-driven 911 sees wet roads and sits between drives | No rusty rotor ring staring back at you through the spokes |
| Crackle-texture ceramic finish | The brake hardware is a styling element on this car, not just function | A clean, premium look behind the wheels without fabricated-bracket clutter |
What gets better
- About 18 kg less unsprung weight versus iron rotors
- Consistent pedal through repeated hard stops
- Cleaner wheels with very low brake dust
- No rust streaks after wet weather or storage
- Long street life, roughly 250,000–300,000 km when not tracked
- OEM-style look, no fabricated-bracket appearance
What to confirm first
- Your 992 variant and current caliper/rotor hardware
- Front wheel clearance: spoke profile, offset, inner barrel shape
- That you're matching the correct rotor size: 420 mm front, 390 mm rear
- Rotor and pad ordered together as one system
- Whether your wheels are OEM or aftermarket before final sizing
If you're not sure your car matches the spec shown here, send us your 992 details and wheel info and we'll confirm fitment before you order through our Porsche CCB collection.

992 carbon ceramic FAQ
Can you retrofit PCCB-style brakes onto a standard Porsche 911 992 Carrera?
Yes. A 992 Carrera-based car can run larger OEM-style Porsche PCCB calipers with STOPFLEX carbon ceramic rotors once the hardware, rotor size, and wheel clearance are matched correctly.
What rotor sizes does this 992 carbon ceramic build use?
It is built around 420 mm front rotors and 390 mm rear rotors for the 992 platform.
Do STOPFLEX rotors work with OEM-style Porsche calipers?
Yes. Ordered for the correct Porsche application, STOPFLEX carbon ceramic rotors are built for OEM-style fitment and work with factory-type calipers in a properly configured retrofit.
Do I need to check wheel clearance before this upgrade?
Yes. The larger front caliper and 420 mm rotor leave little room inside the wheel, so spoke profile, offset, and inner barrel shape all need confirming, especially on aftermarket wheels.
How much weight does this 992 carbon ceramic conversion save?
This build references about 18 kg (roughly 40 lb) of unsprung weight cut versus the iron setup, since STOPFLEX carbon ceramic rotors weigh about half what same-size steel rotors do.
