2022-2027 Porsche 911 (992) GT3 / RS / S/T / Sport Classic CCB Big Brake Kit — Genuine Brembo OEM Porsche 911 GT3 6-Piston Caliper Front + Genuine Brembo OEM Porsche 911 GT3 4-Piston Caliper Rear Setup
This StopFlex kit is for 992 GT3, GT3 RS, S/T, and Sport Classic owners who need carbon-ceramic heat capacity without guessing around Porsche trim-specific brake geometry. The package pairs a Genuine Brembo OEM Porsche 911 GT3 6-Piston Caliper with a 410mm front carbon-ceramic rotor and a Genuine Brembo OEM Porsche 911 GT3 4-Piston Caliper with a 390mm rear carbon-ceramic rotor. The result is lower brake dust on open Porsche wheels, reduced rotating mass compared with iron discs, and fitment engineered around the customer’s exact 992 trim rather than a generic 911 chassis assumption.
- 410mm front and 390mm rear carbon-ceramic rotors are sized for the GT3-family brake envelope, so the kit requires 21-inch or larger wheels plus confirmed spoke clearance.
- The front axle uses the exact Genuine Brembo OEM Porsche 911 GT3 6-Piston Caliper, matched to StopFlex carbon-ceramic rotors, pads, hats, hardware, and lines.
- Brake pad wear sensors remain compatible with the Porsche OEM wear-sensor system, so factory pad-wear warnings continue to function without dashboard errors.

Every StopFlex kit is bespoke-engineered for your exact model and trim — the brackets, rotor-hat offsets, and caliper mounting are matched to your specific car, not assumed from the platform. This matters because trims that share a chassis name can differ mechanically: a pure M or performance variant often carries different front knuckles/uprights, hub geometry, and wheel axial (ET) clearance than the standard models in the same family, so a bracket and hat offset that bolt onto one are not the same parts that fit the other. StopFlex supplies the calipers, pads, rotor hats, floating hardware, and brake lines as a matched system built to your confirmed trim. Cars with modified knuckles, modified uprights, or non-factory suspension mounting points must be reviewed before ordering and are not treated as direct-fit.
This setup uses a 410 mm front 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.

Caliper Overview — Front & Rear Balance
Front Caliper (Primary Upgrade)
The front axle uses the Genuine Brembo OEM Porsche 911 GT3 6-Piston Caliper, a Porsche GT3-derived Brembo fixed caliper chosen for high, repeatable clamping force across the 410mm carbon-ceramic rotor. The six-piston layout distributes pad pressure across a large pad area, which supports stable pedal feel and even pad loading during repeated high-speed stops. Its OEM-derived Brembo construction gives this kit a known Porsche performance-caliper foundation instead of an unproven universal caliper body.
Rear Caliper (Balance)
The rear axle uses the Genuine Brembo OEM Porsche 911 GT3 4-Piston Caliper with a 390mm carbon-ceramic rotor to keep rear brake contribution matched to the front upgrade. The rear package is engineered to retain the Porsche electronic parking brake function where equipped.
Front & rear, engineered together: The 410mm front and 390mm rear carbon-ceramic package is engineered as a complete system so hydraulic balance, rotor diameter, pad selection, hat offset, and caliper position are not treated as separate front-only changes. That matters on a rear-engine 992 because rear brake contribution affects stability, ABS behavior, and confidence when trail braking into a corner.
Make It Yours — Color & Logo Customization
Every StopFlex kit-upgrade order can be finished with custom caliper colors, a custom caliper logo, and custom rotor hat colors, so the brake package matches your exact build instead of a fixed off-the-shelf look.

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.
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.

EPB & Rear Caliper Options
This vehicle leaves the factory with an electronic parking brake (EPB) built into the rear brake, so the rear of the kit is built to keep that EPB working. There are two rear paths. The first is a dual-caliper rear: a main performance caliper handles braking while a dedicated EPB actuator caliper is retained alongside it, so the electronic parking brake, auto-hold, and hill-start assist all keep working; on this path the rear performance caliper can be the TTSPORT EP4 / EP4S 4-piston caliper. The second is an EPB-integrated caliper, a single rear caliper with the electromechanical parking-brake motor built in for a cleaner install with fewer parts behind the wheel; on this path the rear is the TTSPORT EP4 / EP4S 4-piston caliper with integrated EPB. Which path fits best depends on your exact trim and EPB configuration, your budget, your appearance preference, and your wheel size and spoke clearance. Confirm your car's rear-brake configuration with StopFlex before ordering so the correct EPB-compatible rear option is built for your kit.
| Rear option | What it is | Rear caliper | Best when |
|---|---|---|---|
| Dual caliper (EPB retained) | Performance caliper plus a dedicated EPB actuator caliper, both fitted on the rear, so the factory electronic parking brake keeps working. | TTSPORT EP4 / EP4S 4-Piston Caliper | You want guaranteed factory EPB, auto-hold, and hill-start behavior preserved. |
| EPB-integrated caliper | A single rear caliper with the electromechanical parking-brake motor built in, for a cleaner install with fewer parts behind the wheel. | TTSPORT EP4 / EP4S 4-Piston Caliper with integrated EPB | You want a cleaner single-caliper rear with full EPB function. |
FAQ
Will this kit fit my exact 992 GT3, GT3 RS, S/T, or Sport Classic?
StopFlex does not treat every 992 as the same brake chassis. Brackets, rotor-hat offsets, and caliper mounting are confirmed for your exact trim because GT models and special variants can differ from standard Carrera-platform hardware and wheel clearance.
What wheel size do I need for the 410mm front rotor?
The largest rotor in this kit is 410mm, so the minimum wheel size is 21 inches. Wheel diameter is only the first check; spoke shape, wheel offset, and caliper face clearance must also be confirmed before the kit is built.
Will the Porsche parking brake and pad-wear warnings still work?
Yes. The rear setup is engineered to retain the factory electronic parking brake function where equipped, and the brake pad wear sensors are 100% compatible with the Porsche OEM wear-sensor system, so the factory pad-wear warning remains active without dashboard errors.
Why move from iron or OEM carbon-ceramic brakes to this StopFlex kit?
Iron rotors add dust and rotating mass, while replacing damaged OEM carbon-ceramic rotors through the dealer can be expensive. This StopFlex package gives the 992 GT3-family car 410mm front and 390mm rear carbon-ceramic hardware with matched Brembo OEM Porsche GT3 calipers, pads, hats, lines, and trim-specific fitment validation.
