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
