Construction & Design:

The rotors feature a two-piece design with a cast iron braking surface and an aluminum hat, reducing overall weight while maintaining strength and durability. This construction improves heat dissipation and reduces thermal distortion during heavy braking. The drilled rotor pattern further aids in cooling and helps evacuate gases and debris from the pad surface.

The 4-piston calipers are crafted to provide even pressure distribution across the brake pads, enhancing stopping power and pedal consistency. The black finish on the rotors not only adds a refined look but also protects against rust and corrosion, ensuring long-lasting performance and aesthetics.
