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 Turbo S 10-Piston Caliper / 420mm 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 420 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

Why Carbon Ceramic — and Why StopFlex

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.

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.

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 runs the Brembo OEM Porsche 911 Turbo S 10-piston caliper over a 420mm carbon-ceramic rotor. Ten pistons spread clamp evenly across a large pad, so the 992 Turbo holds a firm, repeatable pedal through hard back-to-back stops.

Rear Caliper

The rear uses the Brembo OEM Porsche 911 GT3 4-piston caliper on a 390mm carbon-ceramic rotor, adding rear thermal capacity and keeping brake balance stable on track. It retains the factory electronic parking brake function on this 992.

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

Ceramic discs shrug off surface temperatures that would destroy iron, but the rest of the system still heats up: pads, fluid, seals, calipers, and wheels all absorb soak heat during repeated hard stops. For track days, long descents, and sustained hard driving, run brake cooling and high-temperature fluid.

FAQ

Will these carbon ceramic brakes work in cold winter weather?

Yes, with a caveat rooted in physics: a cold carbon-ceramic disc naturally bites less than cold iron on the first stop or two, which is normal, not a fault. StopFlex tunes both the pad compound and the disc ceramic coating for cold starts, so on your 992 Turbo the first-stop feel on a freezing morning comes very close to summer feel. On the coldest first stops, still leave a little extra following distance until the front 420mm and rear 390mm rotors are up to a few degrees of working temperature.

Is this kit really made for my exact 992 Turbo trim?

Yes. Every kit is bespoke-engineered to your confirmed trim, because the Turbo and Turbo S can differ in front upright geometry, hub dimensions, and wheel ET clearance from standard 992 Carrera models. We machine the brackets and set the rotor-hat offsets specifically for your car so the 10-piston front and 4-piston rear calipers sit centered on the rotors. We do not sell this as a platform-wide bolt-on.

What wheels do I need to clear the 420mm front rotors?

The front rotor is 420mm, so you need a minimum 21-inch wheel. Wheels under 21 inches will not clear the disc, and spoke shape matters as much as diameter, since some 21-inch designs sit too close to the 10-piston caliper body. Send us your exact wheel spec during fitment confirmation and we will check clearance before anything ships.

Will my dashboard pad-wear warning still work?

Yes. The kit includes brake pad wear sensors that are fully compatible with the OEM 992 wear-sensor system, so your factory pad-wear warning keeps working with no dashboard errors. The electronic parking brake on the rear GT3 caliper also operates normally.
