The DBA 4000 Series plain rotor for 2004–2011 Mazda RX-8 front is a direct-fit replacement focused on improved thermal stability during repeated braking. Cast from XG-150 high-carbon alloyed iron and Thermally Stability Profiled, it uses DBA's Kangaroo Paw ventilation with 144 diamond and teardrop pillars to enlarge surface area and cooling—up to 30% more area and 20% better cooling than straight-vane rotors—while the HD finish maintains an OE-style appearance.
