• Patented Kangaroo Paw ventilation design with 144 diamond and teardrop patterned pillars
• Up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Premium non-directional cross-drilled and slotted pattern for maximum gas and dust evacuation

Performance Features:

• Thermo-Graphic Heat Paint (TGHP) markings change color at specific temperature thresholds to monitor braking temperatures
• Cubic Boron Nitride (CBN) machine-turned finish minimizes disc thickness variation
• Enhanced heat dissipation for improved braking effectiveness and prolonged brake life
• Designed to handle increased stress and heat in intense braking applications
• Gold finish on non-friction areas for premium appearance

This rotor is sold individually and is ideal for street performance and spirited driving applications where superior heat management and braking performance are essential.
