The Skoda Superb is the ultimate "sleeper" wagon on the MQB platform. For enthusiasts, upgrading to an aftermarket Big Brake Kit (BBK) with steel rotors is often the first step. However, for those demanding absolute peak performance, even oversized steel rotors become a limitation. This build represents the final evolution: upgrading an existing steel BBK to StopFlex Carbon-Ceramic technology.
The Struggle
Even with a high-quality aftermarket steel BBK, physics imposes limits on a heavy wagon:
- Thermal Ceiling: Steel rotors, no matter how large, have a finite heat capacity. Repeated high-speed stops eventually lead to fade as the metal becomes saturated.
- Rotational Inertia: Large 380mm steel rotors are incredibly heavy. This added rotating mass blunts acceleration and makes the suspension feel sluggish over bumps.
- Brake Dust: Performance pads required for steel BBKs generate massive amounts of corrosive dust, ruining the look of custom wheels.
Technical Specification
This "Stage 2" upgrade replaces the heavy steel friction rings of the existing BBK with lightweight 380 mm (15.0 in) StopFlex Carbon-Ceramic rotors, unlocking the full potential of the 6-piston calipers.
| Vehicle | Skoda Superb (MQB Platform) |
|---|---|
| Front Calipers | Aftermarket 6-Piston (Existing) |
| Rear Calipers | Aftermarket 4-Piston (Existing) |
| Front/Rear Rotors | StopFlex C/SiC (380 x 34 mm) |
| Weight Saving | ≈ 50% Reduction vs. Steel BBK |
| Pad Material | CCB-Optimized Ceramic Compound |
Compatibility Redline
This upgrade is a Direct Rotor Replacement for vehicles already equipped with aftermarket Big Brake Kits designed for over 330mm rotors. If you are running the factory single-piston floating calipers, a full caliper upgrade is required first. Please contact us to verify hat offset and annulus depth for your specific BBK.
Engineering Validation
1. Unlocking Agility
The most immediate change is the reduction in unsprung mass. By swapping heavy steel rings for carbon-ceramic, we remove approx. 10-12 kg of rotating weight per axle. This allows the suspension to react instantly to road imperfections, transforming the Superb's handling from "heavy cruiser" to "agile sports sedan."
2. Infinite Thermal Headroom
StopFlex rotors maintain a stable 0.44–0.52 μ operating window even at temperatures exceeding 900 °C. Where steel rotors would begin to glow and fade, carbon-ceramic provides consistent, rock-hard pedal feel, lap after lap.
3. Proprietary Bright & Glossy Coating
StopFlex utilizes a proprietary ceramic top coat that keeps the rotor surface bright and glossy. Unlike steel rotors that develop unsightly rust rings after washing, this treatment ensures the brakes look showroom-fresh at all times, perfectly complementing the sleeper aesthetic.
4. 3D Continuous Long-Fiber Skeleton
StopFlex utilizes a 3D Continuous Long-Fiber skeleton with a tensile strength of 140 MPa. This is significantly stronger than chopped-fiber alternatives, ensuring the rotors can withstand the high clamping forces of 6-piston motorsport calipers for a service life of up to 300,000 km.

In-Depth Skoda Superb FAQ
Q: I already have a big brake kit. Can I just swap my steel rotors for yours?
In many cases, yes. Our rotor kits are designed to be a bolt-on replacement for common steel disc sizes, like 380x34mm. If your existing calipers accommodate this size, our system is the ultimate "Stage 2" upgrade to eliminate fade and dramatically reduce unsprung weight.
Q: Is the performance gain from steel BBK to carbon-ceramic noticeable?
Absolutely. It's a night-and-day difference in two key areas. First, thermal capacity: you move from "fade-resistant" to "fade-proof." Second, and most critical for daily driving, is the agility gained from the massive reduction in rotational mass. The car will accelerate, turn, and stop with significantly more urgency.
Q: Will this solve the brake dust problem?
Yes. Steel BBKs typically require aggressive semi-metallic pads that produce heavy dust. StopFlex CCB rotors use a specific ceramic compound that produces virtually zero corrosive dust, keeping your wheels clean for weeks.
Q: Do these rotors squeal like race brakes?
No. When paired with our CCB-optimized street pads and properly bedded, the system is engineered to be silent. We eliminate the low-speed squeal often associated with high-friction steel setups.
Q: What is the lifespan of these rotors?
For a street-driven vehicle, StopFlex long-fiber rotors are effectively a "lifetime" component, capable of exceeding 250,000 km. This offsets the initial cost by eliminating the need for frequent rotor replacements common with steel BBKs.
