About the CSI-01B compound

CSI-01B · The designated compound

The designated formula for short-fiber molded coated carbon-ceramic discs — built on the CSI-01 lineage dating to 2019. High performance and low noise, finally unified. And cold bite that Ferrari and Lamborghini carbon-ceramic systems have always lacked.

  • Temperature window: −30–600°C
  • Friction: μ 0.40–0.43
  • Noise rating: SAE J2521 AA
  • Disc: Carbon-ceramic
  • SAE J2521 noise rating AA — on unmodified bare pads
  • Friction rises with temperature — exceeding 1.0 μ in fade tests
  • 2,000+ vehicles on road · fewer than 5 noise cases
  • Ideal for: Carbon-ceramic street cars, including Ferrari and Lamborghini CCB systems
