SBD CCB Brakes for 992.1 GT3 Touring

1. High Strength-to-Weight Ratio

• SBD’s CCM/CCB brake rotors only use T700 carbon fiber. T700 carbon fiber has excellent tensile strength (~4900 MPa) and a high modulus (~230 GPa), making it ideal for high-performance structural components. When used in rotors, this means better strength with less material, reducing overall brake mass. This helps lower unsprung weight and rotational inertia, leading to improved acceleration, handling, and suspension response. T700 rotors have ~40% higher tensile strength than T300-based rotors. This means they can withstand higher loads, faster heat cycling, and more aggressive braking without degradation.

2. Superior Thermal Resistance

• T700 carbon fibers maintain structural integrity at very high temperatures. Carbon-ceramic rotors made with T700 can withstand operating temperatures over 1000°C without significant degradation. Normally, SBD’s T700-based CCM rotor’s highest temperature is around 500°C even for intensive street use.
• While both T300 and T700 have high heat tolerance (>1000°C), T700 composites are more stable under repeated thermal stress. This is crucial for: Consistent brake performance under repeated hard braking.
  • Fade resistance during extreme driving conditions like track use or long downhill braking.

3. Improved Heat Dissipation

• The high thermal conductivity of carbon fiber composites aids in dispersing heat evenly across the rotor. Combined with ceramic matrix material (typically silicon carbide), T700-based rotors cool faster and are less prone to hot spots or thermal cracks compared to T300 and iron rotors.
• SBD’s CCM uses a special directional vane design for better heat dissipation. With this design, it has a 5%-10% faster cooling rate (from 500°C to cool down) than our competitors.

4. Exceptional Durability and Longevity

• Carbon-ceramic rotors are known to last 3–5 times longer than conventional iron rotors under normal conditions. T700’s high fatigue resistance further improves this, especially in applications with frequent thermal cycling. This also reduces the total cost of ownership despite the higher upfront cost. The total longevity for normal use is over 350,000 miles.
• SBD’s CCM brake rotors have been tested at 7000 wheel rotation speed (equivalent to 300 MPH), and not damaged.
• Also, SBD uses Coated 7075 aluminum hats for better reliability. Below is a general comparison between 6066-T6 and 7075-T6.

Property	6066-T6	7075-T6/T651
Ultimate Tensile Strength	~310 MPa (45 ksi)	~570 MPa (83 ksi)
Yield Strength	~275 MPa (40 ksi)	~505 MPa (73 ksi)
Hardness (Brinell)	~95	~150
Corrosion Resistance	Good	Fair (with coating will be better)
Machinability	Good	Excellent
Weldability	Good	Poor (prone to cracking)
Anodizing	Acceptable	Acceptable, but more difficult
Cost	Lower	Higher
Density	~2.78 g/cm³	~2.81 g/cm³

 

5. Weight Reduction = Performance Gain

• A single T700 carbon-ceramic rotor can weigh 40–60% less than a similar-sized iron rotor, and SBD’s T700（2.4 g/cm³） based rotors have a higher density (~1.80 g/cm³) than T300 CCM. The T700 carbon-ceramic rotor can reduce:
  • Rotational mass, improves throttle response.
  • Unsprung weight, enhancing suspension performance.
  • Overall vehicle weight helps fuel efficiency or electric vehicle range.

6. Corrosion Resistance

• Traditional steel or cast iron rotors can rust over time, especially in humid or salty environments. T700 carbon fibers embedded in a ceramic matrix are inert and non-corrosive, ensuring long-term reliability and aesthetics.
• SBD’s CCM rotor has been tested with an intensive Salt Spray experiment, condition 5% NaCl, ambient temperature at 35±2℃, and in a 480-hour continuous test, with no surface or weight changes before & after the test.

7. Noise and Vibration Damping

• T700-based composites have better damping characteristics, which help reduce brake squeal and vibration. This provides a quieter, smoother braking experience, especially in high-end or luxury vehicles.

8. Consistent Friction Coefficient

• Carbon ceramic rotors using T700 maintain a more stable coefficient of friction across temperature ranges compared to metal-based rotors.
• This translates to:
  • Predictable pedal feel
  • More linear braking performance
  • Better modulation during high-speed deceleration

9. OEM Level Manufacturing

• There are many suppliers in the market; product consistency is an issue for smaller manufacturers.
• Our supplier is a Tier 1 OEM with decades of experience in the CCM industry, ensuring quality & safety are not compromised.

There are serial numbers on the rotors; make sure you install the rotors properly. If the serial number is an odd number, that means the DRIVER side, an even number means the PASSENGER side.
