This brake rotor is crafted from high-quality cast iron, known for its excellent thermal conductivity and strength. The drilled and slotted design enhances airflow around the rotor surface, allowing heat to escape more efficiently and reducing the risk of warping under extreme conditions. The silver coating provides an extra layer of protection against rust and corrosion, ensuring the rotor maintains its performance and appearance over time.

R1 Concepts employs precision CNC machining to guarantee exact dimensions and surface flatness, which helps prevent vibrations and uneven pad wear. This attention to detail ensures a smooth, quiet braking experience while maximizing rotor lifespan.
