2014-2019 Porsche 911 (991) Targa / S / GTS Carbon Ceramic Brake Kit — OEM-Size Replacement
This OEM-replacement StopFlex carbon-ceramic kit is built for 2014-2019 Porsche 911 (991) Targa 4, Targa 4S, and Targa 4 GTS cars using the exact factory rotor sizes listed for this page. It replaces the heavy iron setup or a worn PCCB setup with carbon-ceramic rotors, matched pads, hats, and floating hardware while preserving the factory caliper architecture: 330 mm front on Targa 4, 340 mm or 350 mm front on 4S/4 GTS, and PCCB sizes up to 410 mm front depending on model year and option package. The payoff is lower rotating mass, less visible brake dust on open Targa wheels, and better heat stability during repeated canyon or track braking without giving up OEM-style fitment checks.
- Direct OEM-size coverage for 991 Targa 4 front/rear 330 mm iron brakes, 991 Targa 4S/4 GTS 340 mm or 350 mm front and 330 mm or 350 mm rear iron brakes, and PCCB 350/410 mm front with 350/390 mm rear configurations by model year and package.
- Includes carbon-ceramic rotors, pads, hats, and floating hardware, so the 991 Targa’s factory calipers stay in place instead of converting the car to a non-OEM brake architecture.
- Pad wear sensors are compatible with the Porsche 991 factory wear-sensor system, keeping the dashboard pad-wear warning functional without sensor bypasses or fault lights.

| Page type | OEM-size carbon ceramic replacement |
| Minimum wheel size | 17" (for the 330 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 330 mm rotor, so the minimum wheel size is 17". Wheels under 17" 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 2014-2019 Porsche 911 Targa?
No. This page is limited to 991-generation Targa 4, Targa 4S, and Targa 4 GTS models with the exact rotor sizes listed here. Before ordering, confirm your front and rear rotor diameters, model year, trim, and whether the car has PCCB from the factory.
What should I confirm before ordering for a 991 Targa 4S or Targa 4 GTS?
Confirm whether your car uses 340 mm or 350 mm front iron rotors, 330 mm or 350 mm rear rotors, or a PCCB package with 350 mm or 410 mm front and 350 mm or 390 mm rear rotors. VIN/build-sheet and rotor measurements are the safest way to match the correct StopFlex kit.
Will the electronic parking brake and pad-wear warning still work?
The kit is designed as an OEM-size replacement for the listed 991 Targa brake configurations, so the rear brake layout is not converted away from the Porsche parking-brake arrangement. The included pad setup is compatible with the factory Porsche wear-sensor system, so the OEM pad-wear warning remains active without dashboard errors.
Why switch a 991 Targa from iron rotors or worn PCCB to StopFlex carbon ceramic?
Iron rotors add rotating and unsprung mass and produce dark dust on the 991 Targa’s visible wheels; worn or cracked Porsche PCCB rotors are expensive to replace through dealer channels. StopFlex carbon ceramic keeps the OEM-size fitment while reducing brake dust, improving heat stability, and replacing the rotor-and-pad wear package as a matched system.
