Porsche OE Akebono 10-Piston Caliper with StopFlex Carbon Ceramic Brake Disc Big Brake Kit
Official Warranty: 1‑year free replacement for quality defects or coating issues under normal (non-track) use.
StopFlex Carbon Ceramic Brake Disc Kit (C/SiC) + Porsche OE Akebono 10-Piston Calipers
Built for fast street cars and street + occasional track use that want cleaner wheels, fewer replacements, and stable braking when heat builds. This is a made-to-order front-axle package sized around your wheels and brake setup so it installs cleanly—not “close enough.”
What changes for you (real-world):
- More confident pedal: stiff fixed calipers + a matched pad/disc system for consistent response in repeated stops.
- Cleaner wheels: lower visible dust and no orange “flash rust” rotor faces after rain or storage.
- Longer replacement cycle: StopFlex targets 250,000–300,000 km typical road use when used as intended.
- Better front-end response: carbon-ceramic systems are commonly much lighter than comparable iron discs, helping steering and ride compliance.
Fitment confirmation (we keep it simple):
- Year / Make / Model / Wheel Size (VIN helps)
We finalize disc size (330–440 mm), hat geometry, and pad spec around your wheel barrel/spokes and your current brake setup so the kit clears properly and runs the correct pad sweep.
Bolt-On Package List
| Item | What it is | Why it matters |
|---|---|---|
| StopFlex Street Carbon Ceramic Discs (C/SiC) | Street-focused carbon-ceramic friction rings engineered for road temperatures and repeated high-energy stops. | Stable braking surface, reduced corrosion issues, and a long replacement cycle. |
| StopFlex CNC-machined Aluminum Hats | Application-specific hats with the correct offset and mounting geometry. | Correct alignment + wheel clearance, consistent pad sweep, and clean installation. |
| Porsche Akebono 10-Piston Calipers | Fixed multi-piston calipers selected to match disc sizing and pad shape for your application. | Even clamp distribution across a large pad area for consistent response under load. |
| StopFlex CCB-optimized Pad Set (Match Your Calipers) | Pad compound selected for carbon-ceramic discs and matched to your caliper shape. | Helps maintain a stable friction layer and avoids “wrong pad on CCB” issues (noise, inconsistent bite, accelerated surface wear). |
Note: Final disc size, hat offset, and pad spec are confirmed after the fitment step. We prefer “correct fit + correct pad match” over generic claims.
Carbon-Ceramic vs. Cast-Iron / Steel Discs
| Item | StopFlex Carbon-Ceramic (C/SiC) | Cast-Iron / Steel Disc |
|---|---|---|
| Typical disc weight (same size class) | Often ~40–60% lighter than comparable iron discs of similar size. | Heavier rotating mass at the wheel. |
| Service life (typical road use) | 250,000–300,000 km target for typical road use (conditions matter: vehicle weight, driving style, pad choice). | Common guidance is ~30,000–70,000 miles (≈48,000–113,000 km), strongly usage-dependent. |
| Corrosion & appearance | No flash rust; stays visually clean behind the wheel. | Surface rust after rain/storage is normal; cosmetic “orange” is common. |
| High-temperature stability | Designed to remain stable in repeated high-energy stops. Common wrong-use risks are impact damage (chips) and pad mismatch (unstable friction layer / accelerated wear). | For repeated high-energy use, iron systems can experience hot spotting, thermal cracking, and increased heat soak into pads/fluid if cooling is insufficient. |
| Track reality check | Short sessions: great. Long lapping: plan ducts/airflow and manage pad + fluid temps. | Often more forgiving with the “right” track pad + airflow, but heavier and typically needs more frequent rotor replacement. |
Bottom line: If you’re mainly fast-road with occasional track sessions and you care about clean wheels + long-term durability, carbon-ceramic is a clear step up. If you do long, heavy track days without cooling upgrades, plan airflow before you switch.
Choose Your Disc Style
Three variants built around the same long-fiber carbon-ceramic core. Pick the one that matches how you actually drive.
Street
- Face design: Drilled + Big Cooling Holes
- Cooling core: Directional internal venting
- Coating: Ceramic coating (street durability + clean look)
- Use: Daily, canyon runs, highway pulls, short light track sessions
Track-Day
- Face design: Blank + Hive Cooling Holes
- Cooling core: Hive-style internal cooling
- Coating: Ceramic coating (balanced street + heat tolerance)
- Use: Street + occasional track days (best with proper brake ducts)
Race-Only
- Face design: Blank + Hive Cooling Holes
- Cooling core: Hive-style internal cooling
- Coating: No coating (race-focused surface)
- Use: Dedicated track/race cars with strong cooling and regular inspections
Note: Not intended for street use.

Specs are finalized per vehicle and wheel clearance. We keep it honest: the details that matter are the ones that make it fit and work.
FAQ
Is this a universal kit?
No. The kit is made-to-order. We confirm your Year / Make / Model / Wheel Size (VIN helps) and build the hat geometry + disc size to clear your wheels and match your setup.
Will it work from cold on the street?
Yes—when paired with the specified StopFlex CCB-optimized Pad Set (Match Your Calipers). The goal is normal street bite from cold, not “needs heat to work.”
How long do the discs last?
For typical road use, StopFlex targets 250,000–300,000 km. Real life depends on vehicle weight, driving style, pad choice, and how often you do track sessions.
Do I need cooling upgrades for track use?
For street and short stints, you’re fine. For long lapping sessions, plan proper ducts/venting. On track, pads and fluid often become the limiting factor without airflow.
Can I use any pad that fits my calipers?
Not recommended. Pad chemistry matters more on carbon-ceramic. A wrong pad can create unstable friction, noise, and unnecessary surface wear. Use the StopFlex CCB-optimized Pad Set (Match Your Calipers) specified for your setup.
Is there a bed-in process?
Yes. A controlled bed-in builds a consistent friction layer. We provide a simple procedure with the kit (moderate stops, then cool-down—avoid long pedal holds while hot).
