Will This Fit My Car?
Full Upgrade CCB Big Brake Kits (With Calipers) for the 2010-2011 Porsche 911 (997) Sport Classic. This page's exact brake setup:
| Model Years | Front Setup | Rear Setup | Min. Wheel Size |
|---|---|---|---|
| 2010-2011 | Brembo OEM Porsche 911 GT3 6-Piston Caliper / 405mm | 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 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 |
|---|---|
| 15" | 260 mm – 285 mm |
| 16" | 285 mm – 300 mm |
| 17" | 300 mm – 330 mm |
| 18" | 330 mm – 355 mm |
| 19" | 355 mm – 380 mm |
| 20" | 380 mm – 400 mm |
| 21" | 400 mm – 420 mm |
| 22" | 420 mm – 440 mm |

Why Carbon Ceramic — and Why StopFlex
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.
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.
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 caliper is the Brembo OEM Porsche 911 GT3 6-piston unit, the same monobloc caliper Porsche specified for the GT3. Six pistons spread clamping load evenly across the 405mm disc for a firm, repeatable pedal even after repeated hard stops.
Rear Caliper
The rear runs the Brembo OEM Porsche 911 GT3 4-piston caliper on a 390mm disc, adding rear thermal capacity and balanced braking under sustained load. It bolts to a bracket cut for the Sport Classic's rear geometry.
Choose Your Rotor: Street, Track-Day, or Motorsport

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.
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
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 kit fit my exact Sport Classic, or is it a generic 997 kit?
It is engineered for the confirmed 2010-2011 997 Sport Classic, not the whole 997 platform. The Sport Classic uses its own front and rear geometry, so the brackets, rotor-hat offsets, and caliper mounting are cut to match your car specifically. We confirm your VIN and trim before building; we never assume platform-wide bolt-on fit across 997 variants that share a chassis name.
What wheels do I need to clear these brakes?
The front rotor is 405mm, so you need a minimum 21-inch wheel to clear the caliper and disc. Spoke geometry also matters at this diameter, not just the nominal wheel size, so send us your wheel details and we'll verify clearance before you order.
How do carbon ceramics behave on a cold winter morning?
An untuned cold carbon-ceramic disc bites less than cold iron on the first stops. That's normal physics. We've optimized both the pad compound and the disc's ceramic coating for cold starts, so cold-car winter feel comes very close to summer feel. On the coldest first stops, leave a little extra following distance until the system is up to temperature.
Will my dashboard pad-wear warning still work?
Yes. The kit includes brake pad wear sensors that are fully compatible with your Porsche's OEM wear-sensor system, so the factory pad-wear warning keeps functioning with no dashboard errors. The car reads the new pads exactly as it read the originals.
