2019 Porsche 911 (991) Speedster Carbon Ceramic Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
2019 Porsche 911 (991) Speedster Carbon Ceramic Brake Kit — OEM-Size Replacement
The 2019 Porsche 911 Speedster uses the 991 GT-derived PCCB package: 410mm front and 390mm rear carbon-ceramic rotors with fixed monobloc calipers. This StopFlex OEM-size replacement kit is for owners replacing worn, heat-checked, or cracked factory ceramic rotors while keeping the Speedster’s original brake balance, yellow-caliper fitment, low dust, and reduced unsprung weight. The kit includes carbon-ceramic rotors, matched pads, hats, and floating hardware, with pad wear sensors that remain compatible with the Porsche factory warning system.
- Direct OEM-size replacement for the 2019 911 Speedster PCCB setup: 410mm front rotors and 390mm rear rotors.
- Built for the Speedster’s GT-based fixed-caliper brake package, not for smaller 991 Carrera, Carrera S, or non-PCCB rotor configurations.
- Compatible pad wear sensors keep the Porsche factory pad-wear warning active without dashboard errors.
Fitment Hard Lines
| Field | Specification |
|---|---|
| Vehicle | Porsche 911 (991) Speedster |
| Model years | 2019 |
| Front rotor reference | Speedster: 410mm (PCCB) |
| Rear rotor reference | Speedster: 390mm (PCCB) |
| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 21" (for the 410 mm rotor) |
For OEM replacement orders, StopFlex builds around the factory rotor specification shown for this vehicle. Front floating-caliper setups require manual review before production. If the car uses aftermarket calipers such as Brembo, AP Racing, Alcon, or Wilwood, the order can still be built, but the exact caliper model, pad shape, and rotor dimensions must be confirmed before production.
This setup uses a 410 mm rotor, so the minimum wheel size is 21". Wheels under 21" will not clear the caliper and rotor, and spoke profile and offset affect clearance too — confirm your exact wheels before ordering.
Why StopFlex CCB
Lower Unsprung Mass
StopFlex carbon-ceramic rotors are engineered to reduce rotor mass versus comparable iron discs, helping the suspension react cleaner and the steering feel more precise.
High-Temperature Stability
The carbon-silicon-carbide matrix is built for stable braking behavior at temperatures that can push iron rotors into heavy fade.
Rust-Free Rotor Surface
Carbon ceramic does not form orange flash rust after rain, washing, or storage, keeping the visible rotor face cleaner behind open wheels.
Long Street-Service Potential
In normal road use with matched pads and proper bedding, StopFlex CCB rotors are designed for far longer service life than typical iron replacement rotors.
Low Visible Dust
When paired with matched StopFlex pads, the system produces very low visible brake dust compared with conventional iron rotor and pad combinations.
Premium Ceramic-Glaze Appearance
StopFlex's proprietary coating creates a bright, high-end ceramic-glaze finish with subtle glaze texture and a more premium visual character behind open wheels.
Street-Usable Cold Bite
Street Spec and Track-Day Spec rotors are designed for normal first-stop road use, including cold-weather operation. Motorsport Spec is the competition-focused exception.
Continuous Fiber Reinforcement
Long-fiber carbon ceramic construction improves structural strength and thermal durability versus chopped-fiber approaches.
Custom Rotor Hat Color
Every StopFlex OEM replacement order can be built with a custom rotor hat color, giving the carbon ceramic rotor package a cleaner match with the wheel, body color, and overall build style.
Heat Management Note
Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat can still soak into pads, fluid, seals, calipers, wheels, and nearby components. For long track sessions, mountain descents, or sustained aggressive driving, brake cooling and high-temperature fluid are still recommended.
Street / Track-Day / Motorsport Rotor Options
Street Spec
Ceramic coating, cross-drilled face, and large cooling channels.
Best for daily driving and premium street builds that need clean cold bite, low dust, corrosion-free appearance, and long service life.
Track-Day Spec
Ceramic coating, blank face, and honeycomb cooling channels.
Best for fast-road and track-day use where repeated braking stability matters more than maximum visual drilling style.
Motorsport Spec
Uncoated blank face with honeycomb cooling channels.
Best for race-focused builds that run competition pads, high-temperature fluid, cooling strategy, and a proper warm-up window. Not the default street choice.

FAQ
Will this kit fit every 2019 Porsche 911 Speedster?
It is built for the 2019 911 (991) Speedster with the factory PCCB rotor sizes listed here: 410mm front and 390mm rear. Before ordering, confirm your VIN, existing rotor diameter, and caliper package because this page is not for smaller 991 brake systems.
Will the factory pad-wear warning still work?
Yes. This Speedster kit includes brake pad wear sensors that are compatible with the OEM Porsche wear-sensor system, so the factory pad-wear warning remains functional with no sensor-related dashboard errors.
Does this change the parking brake or rear electronics?
No conversion is required for the rear brake interface when the car has the correct 390mm PCCB rear setup. The kit replaces the rotors, pads, hats, and floating hardware while preserving the OEM-size layout used by the Speedster.
Why replace the factory PCCB rotors with StopFlex instead of switching to iron?
Iron conversions can add rotating mass, increase wheel dust, and change the brake feel that Porsche engineered into the Speedster. StopFlex keeps the 410mm/390mm carbon-ceramic format for low dust, high heat capacity, and the steering response expected from this 991 GT-based chassis.
