About the Disc

Will This Fit My Car?

Full Upgrade CCB Big Brake Kits (With Calipers) for the 2021-2026+ Porsche 911 (992) Turbo. This page's exact brake setup:

Model Years Front Setup Rear Setup Min. Wheel Size
2021-2026+ Brembo OEM Porsche 911 GT3 6-Piston Caliper / 410mm Brembo OEM Porsche 911 GT3 4-Piston Caliper / 390mm 21"

Fitment here is bespoke: brackets, hat offsets, and caliper mounting are engineered for your exact model and trim rather than copied across the platform. Two trims with the same chassis code can still differ in knuckles, hub geometry, and wheel ET clearance — which is why we confirm your trim first, then build the matched system of calipers, pads, rotor hats, floating hardware, and lines for it. Modified knuckles, uprights, or non-factory suspension points require review before ordering.

The 410 mm rotor sets the minimum wheel size at 21" — smaller wheels will not clear the caliper and rotor. Spoke profile and offset also affect clearance; confirm your exact wheels before ordering.

Wheel Size (Standard) Disc Range
15" 260 mm – 285 mm
16" 285 mm – 300 mm
17" 300 mm – 330 mm

Why Carbon Ceramic — and Why StopFlex

CCB-Specific Pad Compound

A low-metallic resin pad compound reinforced with steel, copper, and aramid fiber, made for ceramic discs: stable to about 750 °C, roughly 0.44 average friction, strong fade resistance, low rotor wear.

Lower Unsprung Mass

A carbon-ceramic rotor weighs roughly half of the equivalent iron disc. Less rotating, unsprung mass lets the suspension follow broken pavement more cleanly and makes steering response noticeably sharper.

High-Temperature Stability

The carbon-silicon-carbide friction matrix keeps working at temperatures that push iron rotors into heavy fade, so the tenth hard stop feels like the first — same pedal travel, same bite point.

Rust-Free Rotor Surface

Ceramic discs cannot flash-rust. After rain, a wash, or weeks of parking, the rotor face behind your open-spoke wheels stays clean — no orange ring on a freshly detailed car.

Long Street-Service Life

In normal road use with matched pads and correct bedding, one StopFlex CCB rotor set is engineered to outlast several sets of iron replacement rotors, recovering part of the up-front cost.

Low Visible Dust

Matched with StopFlex pads, the system sheds a fraction of the dust an iron rotor and pad combination throws. Wheels stay clean for weeks of driving instead of days.

Premium Ceramic-Glaze Finish

StopFlex's proprietary coating gives the disc a bright ceramic-glaze surface with subtle texture — the factory carbon-ceramic look, clearly visible through open wheel designs.

Continuous Fiber Construction

StopFlex discs are built with long continuous carbon fiber instead of chopped short fiber. Continuous strands carry load across the whole rotor body, raising strength and thermal durability under heat cycles.

Bespoke Per-Vehicle Engineering

Every order is machined to the confirmed vehicle and trim. Brackets, hat offsets, and pad shapes are built for that exact car — never pulled from a one-size-fits-all catalog.

Winter & Cold-Weather Braking

Cold facts first: an untuned ceramic disc bites less than iron on a freezing morning — physics, not a defect. StopFlex tuned both the pad compound and the disc's ceramic coating for cold starts, so winter cold-car braking now feels very close to summer. Leave extra margin on the very coldest first stops; severe-climate daily drivers should build Street Spec.

Caliper Overview

Front Caliper

The front uses the Brembo OEM Porsche 911 GT3 6-piston caliper, the same monobloc unit engineered for GT3 clamping duty. Six pistons spread pad pressure evenly across the 410mm disc for a firm, repeatable pedal lap after lap.

Rear Caliper

The rear runs the Brembo OEM Porsche 911 GT3 4-piston caliper, adding rear thermal capacity to balance the front bite and hold pedal feel under sustained heat. It's mounted to brackets cut for your confirmed 992 Turbo trim.

Choose Your Rotor: Street, Track-Day, or Motorsport

StopFlex Street Spec carbon ceramic brake rotor

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.

StopFlex Track-Day Spec carbon ceramic brake rotor

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.

StopFlex Motorsport Spec carbon ceramic brake rotor

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.

Heat Management Note

High rotor temperature tolerance does not mean heat management disappears. Under repeated hard braking, heat migrates into the pads, brake fluid, seals, calipers, and wheels even when the ceramic disc itself is comfortable. Plan brake cooling and high-temperature fluid for extended track sessions, long mountain descents, or sustained aggressive driving.

Get Your Fitment Confirmed

Before ordering, tell us the exact vehicle, current rotor sizes, and caliper type. Nothing goes to production until the build is confirmed against your VIN-level configuration.

FAQ

How does this kit behave in winter or on a cold first stop?

A cold carbon-ceramic disc naturally bites less than cold iron on the very first stops — that's physics, not a fault. StopFlex tunes both the pad compound and the disc's ceramic coating specifically for cold starts, so cold-car feel on your 992 Turbo now comes very close to summer feel. On the coldest mornings, leave a little extra following distance for the first stop or two while the system comes up to temperature.

Will this fit my exact 992 Turbo, or is it a generic 911 kit?

It's bespoke per confirmed trim. The 992 Turbo and Turbo S can differ from standard Carrera models in knuckle geometry, hub offset, and wheel clearance, so we cut the brackets, rotor-hat offsets, and caliper mounting for your exact car after you confirm the trim. We do not make a platform-wide bolt-on claim across the whole 911 family.

What wheels do I need to clear these brakes?

The front rotor is 410mm, so 21-inch wheels are the minimum — anything under 21 inches will not clear the disc. Spoke design matters too, so send us your wheel details and we'll confirm caliper-to-spoke clearance before you order.

Will the electric parking brake and pad-wear warning still work?

Yes. The rear GT3 4-piston calipers retain the 992's factory electric parking brake function, and the included pad wear sensors are fully compatible with the OEM wear-sensor system. Your factory pad-wear warning keeps working with no dashboard errors.
