The DBA 4000 Series plain rotor for 2004–2008 Mazda RX-8 with normal suspension (front) is a direct-fit replacement engineered for improved thermal handling. Made from XG-150 high-carbon alloyed iron and heat-treated with Thermal Stability Profiling, it uses DBA's Kangaroo Paw 144-pillar ventilation to raise surface area and cooling—offering measurable gains versus straight-vane rotors—while the HD finish preserves a smooth OE-style appearance.
