2007-2011 Porsche 911 (997) GT3 / RS 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
The 2007-2011 Porsche 911 (997) GT3 / RS is often shopped for carbon-ceramic brakes when track heat, iron-rotor dust, or the cost of replacing worn Porsche ceramics becomes the limiting factor. This StopFlex kit pairs a 405mm front rotor with the Genuine Brembo OEM Porsche 911 GT3 6-Piston Caliper and a 390mm rear rotor with the Genuine Brembo OEM Porsche 911 GT3 4-Piston Caliper, giving the car more thermal mass, lower rotating weight than iron, and a cleaner open-wheel brake package. Brackets, rotor-hat offsets, caliper mounting, pads, hardware, and lines are engineered to the customer's exact GT3 or GT3 RS configuration, not assumed from the 997 platform.
- 405mm front and 390mm rear carbon-ceramic rotors are sized for a 997 GT3 / RS buyer prioritizing repeated high-speed braking and lower brake dust on exposed wheels.
- The front axle uses the exact Genuine Brembo OEM Porsche 911 GT3 6-Piston Caliper; the rear axle uses the Genuine Brembo OEM Porsche 911 GT3 4-Piston Caliper to keep the package Porsche GT3-based.
- The 405mm front rotor requires 21-inch or larger wheels, and spoke clearance must be checked before ordering because diameter alone does not confirm caliper clearance.

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 405 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, giving the 405mm rotor a stiff, multi-piston clamp package for stable pedal response and even pad loading. Because the caliper is a genuine Brembo OEM Porsche GT3-derived unit, the upgrade keeps the front brake hardware within a proven Porsche motorsport-style architecture rather than using an anonymous universal caliper. The caliper is paired with StopFlex carbon-ceramic rotors, pads, hats, hardware, and lines as a complete front system.
Rear Caliper (Balance)
The rear axle uses the Genuine Brembo OEM Porsche 911 GT3 4-Piston Caliper with a 390mm carbon-ceramic rotor so rear brake torque, thermal behavior, and stability under trail braking are engineered with the front upgrade. The 997 GT3 / RS uses a manual cable handbrake system, so there is no EPB motor to retain or recalibrate.
Front & rear, engineered together: The 405mm front and 390mm rear package is engineered as a full-car brake system so piston area, rotor diameter, pad compound, and hydraulic response are matched together. That avoids the bias and pedal-feel problems that can come from installing a large front-only kit while leaving the rear axle mechanically mismatched.
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.

- Custom rotor hat color
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.

FAQ
Will this kit fit my exact 997 GT3 or GT3 RS?
Fitment is built around your confirmed year, GT3 or GT3 RS trim, hub geometry, wheel package, and brake configuration. StopFlex does not treat every 997 chassis as the same car; brackets, rotor-hat offsets, and caliper mounting are specified for your exact trim before production.
What wheel size is required for the 405mm front rotor?
The 405mm front rotor requires 21-inch or larger wheels. Wheels under 21 inches will not clear the rotor, and StopFlex still checks spoke clearance because caliper clearance depends on wheel face shape and offset, not diameter alone.
Does the kit keep the Porsche brake pad wear warning system working?
Yes. This Porsche application uses brake pad wear sensors that are 100% compatible with the OEM wear-sensor system, so the factory pad-wear warning remains functional without dashboard errors when the kit is installed correctly.
Why convert a 997 GT3 / RS to this carbon-ceramic kit instead of staying with iron rotors?
For a 997 GT3 / RS used on fast street drives or track days, carbon-ceramic rotors reduce brake dust, reduce rotating mass compared with iron, and handle repeated heat cycles differently than conventional steel discs. This kit also gives owners replacing expensive worn or cracked ceramics a complete caliper, rotor, pad, hat, hardware, and line package instead of piecing together axle-by-axle parts.
