PG SICA Performance High-Performance Two-Piece Series

PG SICA Performance high-performance two-piece discs use an in-house developed, specially tuned multi-element alloy with ±3.7% high carbon content, combined with a proprietary in-house high-temperature heat-treatment process. The result is outstanding tensile strength and resistance to deformation, and strong high-temperature fade resistance. A stable, consistent friction coefficient lets high-performance brake pads deliver their best, while efficient heat dissipation keeps the disc in its optimal operating range during extended spirited driving.

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.
