PG SICA Competition Racing Two-Piece Series

PG SICA Competition racing two-piece discs are built for the brake systems of professional race teams, and are supplied long-term to major professional racing teams in China and overseas for competition use. They use an in-house formulated racing multi-element alloy with ±3.9% carbon content, combined with a proprietary race-grade high-temperature heat-treatment process, giving track-grade tensile strength and resistance to deformation. Competition performance stays stable under high-intensity track conditions, with strong braking friction efficiency and heat dissipation. Used with competition brake pads, the whole race brake system stays in its optimal operating range throughout.

Vortex vane structure: the pressure difference created as the disc rotates drives cool air through the disc body, using forced convection to rapidly expel braking heat. Pre-applied professional-grade temperature-indicating paint gives visual feedback of the disc's operating temperature through colour change, so you can monitor the brake system under high temperature.
