About the Disc

Will This Fit My Car?

Full Upgrade CCB Big Brake Kits (With Calipers) for the 2005-2012 Porsche 911 (997) Carrera. This page's exact brake setup:

Model Years Front Setup Rear Setup Min. Wheel Size
2005-2012 Brembo OEM Porsche 911 GT3 6-Piston Caliper / 405mm Brembo OEM Porsche 911 GT3 4-Piston Caliper / 390mm 21"

This kit is built per car, not per platform. We engineer the brackets, rotor-hat offsets, and caliper mounting to your confirmed model and trim, because trims sharing a chassis name frequently differ underneath — performance variants can run different knuckles, hub geometry, and wheel ET clearance than their standard siblings. You receive calipers, pads, rotor hats, floating hardware, and brake lines as one matched, trim-specific system. Cars with modified knuckles, uprights, or non-factory suspension mounting points need review before ordering.

The 405 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

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.

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.

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 caliper is the Brembo OEM Porsche 911 GT3 6-piston monobloc, the same clamp used on the factory GT3. Six pistons spread pad pressure evenly across the 405mm disc for a firm, repeatable pedal lap after lap.

Rear Caliper

The rear runs the Brembo OEM Porsche 911 GT3 4-piston caliper on a 390mm disc, adding rear thermal capacity so the car stays balanced under hard, repeated braking. It works with the 997 cable parking brake.

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 winter and cold weather?

An untuned cold carbon-ceramic disc bites a little less than cold iron on the first stops — that is normal physics, not a fault. We tune both the pad compound and the disc's ceramic coating for cold starts, so winter cold-car feel comes very close to summer feel. Still leave a bit of extra following distance on the coldest first stops until the system is warm.

Does this fit both the 997 Carrera and Carrera S?

Each kit is engineered for your exact confirmed trim. The 997.1 and 997.2 Carrera and Carrera S can differ in upright and hub geometry, so we build the correct brackets and rotor-hat offsets for your specific car. We do not assume a single platform-wide bolt-on — we confirm your model, year, and trim first.

What wheels do I need to clear the 405mm front rotor?

The 405mm front disc with the GT3 6-piston caliper needs a minimum 21-inch wheel. Anything smaller will not clear the caliper, and spoke shape also matters. Send us your wheel details and we'll confirm clearance before you buy.

Will the factory brake wear warning still work?

Yes. This kit includes pad wear sensors that are fully compatible with the 997's OEM wear-sensor system, so the factory pad-wear warning keeps working with no dashboard errors.
