Alcon RC6 6-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 + Alcon RC6 6-Piston Calipers
Built for fast street cars that want cleaner wheels, fewer rotor replacements, and stable braking when heat builds. Made-to-order discs in your exact sizes, paired with StopFlex CNC-machined Aluminum Hats, Alcon RC6 6-piston front calipers, and a StopFlex CCB-optimized Pad Set (Match Your Calipers).
What changes for you (real-world):
- Less rotating mass: carbon-ceramic systems are commonly about ~50% lighter than comparable steel/iron discs, improving response and reducing load on suspension and hubs.
- Cleaner wheels: low visible dust, no orange “flash rust” after rain or storage.
- Longer replacement cycle: StopFlex targets 250,000–300,000 km typical road use when used as intended (conditions matter).
- Defined, repeatable braking: RC6 6-piston calipers add clamp stability so the system stays predictable when you drive hard.
Fitment confirmation (we keep it simple):
- Year / Make / Model / Wheel Size (VIN helps)
We build disc size (330–440 mm), hat geometry, and pad spec around your wheel clearance and brake setup so the kit installs cleanly. If your wheels are aftermarket or clearance is tight, we may ask for a spoke check using a caliper profile template.
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 surface, reduced corrosion issues, and a long replacement cycle when used correctly. |
| StopFlex CNC-machined Aluminum Hats | Precision hats matched to your application. | Correct alignment and clearance with your hub/wheel package, with consistent pad sweep. |
| 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 the “wrong pad on CCB” problems (noise, inconsistent bite, accelerated surface wear). |
| Alcon RC6 6-Piston Front Calipers | High-stiffness 6-piston calipers paired to the disc size and pad shape for your application. | More stable clamp and more consistent response when braking repeatedly at higher temperatures. |
| Vehicle-specific mounting + fasteners | Brackets, pins/retainers, and the hardware needed to mount and align the system on your chassis. | Correct geometry is what makes “bolt-on” actually bolt-on (clearances, alignment, pad sweep). |
Note: This page is for a front-axle kit format. If you want a full front+rear package, we can quote it as a matched system.
Carbon-Ceramic vs. Cast-Iron / Steel Front Brakes
| Item | StopFlex Carbon-Ceramic (C/SiC) + RC6 | Typical Cast-Iron / Steel Front Brakes |
|---|---|---|
| Typical disc weight (same size class) | Often about ~50% lighter than steel/iron discs of similar size. | Heavier rotating mass at the wheel. |
| Service life (typical road use) | 250,000–300,000 km StopFlex target for typical road use (vehicle weight, driving style, pad choice matter). | 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. |
| Brake dust (visible) | Typically less visible dust with a CCB-optimized pad set. | Dust level depends on pad; many street/track pads can be noticeably dusty. |
| Heat consistency (what changes) | Designed to remain structurally stable under repeated high-energy stops; the system relies on correct pad match and careful setup. | Repeated heavy stops can lead to hot spotting / cracking risk and more heat soak into pads/fluid, depending on duty cycle. |
| Big-kit failure point | Wheel spoke clearance is the #1 reality check—verified before production. | Same issue on BBKs; “looks like it fits” is how people waste money. |
Bottom line: If you’re mainly a fast-road driver who cares about clean wheels + long-term durability, carbon-ceramic is a clear step up. If you run long, heavy track days without cooling upgrades, plan your ducting and 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.
Technical Specifications
| Disc material | StopFlex carbon-ceramic composite (C/SiC), street-focused surface engineered for road use and repeated high-energy stops. |
| Disc diameter range | 330–440 mm (application-specific) |
| Construction | Two-piece disc system with StopFlex CNC-machined Aluminum Hats |
| Pad set | StopFlex CCB-optimized Pad Set (Match Your Calipers) |
| Calipers | Alcon RC6 6-piston front calipers (vehicle-specific mounting + sizing matched during fitment confirmation). |
| Compatibility | Made-to-order sizing and clearance verification required. Fitment confirmation uses Year / Make / Model / Wheel Size (VIN helps). |
Specs are finalized per vehicle and wheel clearance. We prefer “correct fitment + correct pad match” over generic claims.
FAQ
Is this a universal kit?
No. It’s made-to-order. We confirm Year / Make / Model / Wheel Size (VIN helps) and build disc size + hat geometry 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. 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. Carbon-ceramic tends to keep more heat near the friction surface—so pads and fluid become the limiting factor without airflow.
Can I use any pad that fits the RC6 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 this kit.
What’s the #1 reason BBKs fail after purchase?
Wheel spoke clearance. That’s why we confirm fitment up front and may request a spoke check using a caliper profile template when needed.
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).
