The DBA 4000 Series High Carbon Alloyed Iron Front Rotor is engineered for high-performance braking in demanding driving conditions. Crafted from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling, this rotor offers excellent durability and heat resistance. Its unique Kangaroo Paw ventilation system features 144 diamond and teardrop shaped pillars, providing up to a 30% increase in surface area and a 20% improvement in cooling efficiency over traditional straight vane designs. This advanced ventilation technology helps maintain consistent braking performance during intense applications, making it ideal for street and race divisions that require reliable stopping power.
The 4000 Series HD variant features a smooth OE-style rotor finish, delivering a clean, factory-like appearance while offering the benefits of enhanced heat dissipation and durability. Designed as a direct replacement for the original equipment, it is suitable for vehicle owners seeking an OE look combined with high-performance capabilities. The rotor’s thermographic paint markings facilitate heat monitoring, and the moisture-proof packaging ensures corrosion resistance, extending the lifespan of the component. This rotor is compatible with the 2004 Pontiac GTO and is suitable for drivers who demand high-quality aftermarket braking solutions with proven performance in both street and controlled racing environments.
