About the Disc

Will This Fit My Car?

Full Upgrade CCB Big Brake Kits (With Calipers) for the 2008-2011 Porsche 911 (997) GT2. This page's exact brake setup:

Model Years Front Setup Rear Setup Min. Wheel Size
2008-2011 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

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.

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.

Winter & Cold-Weather Braking

A cold, untuned carbon-ceramic disc needs more pedal than iron on the first winter stops — normal material physics. StopFlex engineered the pad formula and disc coating specifically for cold starts, closing that gap: cold-car winter feel is now very close to summer feel. Keep a little extra distance on the coldest mornings; for harsh winters, choose Street Spec.

Caliper Overview

Front Caliper

The front uses the Brembo OEM Porsche 911 GT3 6-piston fixed caliper, the factory GT3 unit paired here with a 405mm carbon-ceramic rotor. Six opposed pistons hold pad pressure even and pedal feel steady from a cold first stop through repeated high-speed braking.

Rear Caliper

The rear runs the Brembo OEM Porsche 911 GT3 4-piston fixed caliper over a 390mm carbon-ceramic rotor, adding balanced rear thermal capacity for hard track use. The 997 GT2 uses a cable parking brake, so there is no electronic actuator to work around.

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

Carbon ceramic rotors tolerate extreme surface temperature, but they do not remove every heat-management requirement. During repeated hard stops, heat still soaks 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.

Get Your Fitment Confirmed

Send the exact vehicle details, current rotor sizes, and caliper type before ordering. Every StopFlex order is confirmed against your VIN-level configuration before production.

FAQ

Will this fit my exact 997 GT2 without guessing off the platform?

Every kit is built to your confirmed trim. The 997 GT2 and GT2 RS carry front knuckles, hub geometry, and wheel clearance that differ from a base 997, so we cut the brackets and set rotor-hat offsets to your specific car rather than assuming a platform fit. We confirm your VIN and trim before anything ships.

What wheels do I need to clear these rotors?

The front rotor is 405mm, so you need at least 21-inch wheels. Anything under 21 inches will not clear the disc, and spoke geometry matters too, so send us your wheel details and we will verify caliper-to-spoke clearance before you buy.

How do these behave in winter and on a cold car?

A cold carbon-ceramic disc naturally bites a little less than cold iron, which is physics, not a fault. We tune both the low-metallic pad compound and the disc's ceramic coating for cold starts, so first-stop feel comes very close to summer. Still, leave a little extra following distance on the coldest first few stops until everything is up to temperature.

Will the pad-wear warning still work on my dash?

Yes. The kit includes brake pad wear sensors that are fully compatible with the OEM Porsche wear-sensor system, so the factory pad-wear warning keeps functioning with no dashboard errors.
