Tested against grey cast iron (HT-250) under SAE J2522 dynamometer conditions. Every metric favours the ceramic matrix — because the material operates in a temperature range where metal fails.

Material Science
RCS carbon-ceramic rotors are built from a continuous 3D long-fibre carbon preform infiltrated with silicon carbide (SiC) ceramic matrix. Unlike short-fibre alternatives, long-fibre construction creates continuous load paths through the material — delivering superior fracture toughness and thermal shock resistance.
Ceramic binder with Mohs hardness 9–9.5 (just below diamond). The friction surface wears the pad, not the rotor.
T700-grade long fibres in quasi-3D woven architecture. Tensile strength exceeds short-fibre alternatives by 3×.
Absorbs 2–3× more thermal energy per degree than cast iron. The rotor soaks up heat instead of transmitting it to the caliper, fluid, and wheel bearings.

Physical Properties
Validated Performance
Tested under SAE J2522 (AMS) low-speed drag protocol — the global industry standard for brake thermal fade evaluation. RCS CCB rotors show negligible friction degradation even after consecutive stops from 135 km/h with braking surface temperatures exceeding 400°C.

RCS CCB systems are engineered for vehicles originally equipped with or upgraded to carbon-ceramic brakes, including Porsche (PCCB), Ferrari/Lamborghini (CCM-R), and high-performance applications requiring 330–440 mm disc diameters with 19"+ wheel clearance.
Every fitment is bespoke. Our engineering team validates hub geometry, caliper clearance, and wheel barrel space before production.
