Construction & Design

The brake rotors in this kit are constructed from high-quality cast iron with a slotted design that enhances heat dissipation and reduces brake fade. The slots also help clear away gases and debris generated during high-speed braking, maintaining consistent contact between the pad and rotor. The rotors are precision-machined to ensure a perfect fit and optimal surface contact, which is critical for high-performance applications.

The brake pads utilize advanced friction materials that are specifically formulated for track conditions. These pads are designed to provide high friction levels at elevated temperatures, ensuring reliable stopping power even after multiple laps. The combination of slotted rotors and high-performance pads results in a braking system that is both responsive and durable under demanding conditions.
