DBA 4000 Series T3 Slot Brake Rotor

The Stillen DBA 4000 Series T3 Slot Brake Rotor is engineered by Disc Brakes Australia, a leading manufacturer of performance aftermarket brake components. Designed as a direct replacement, these rotors offer a significant upgrade over standard OE levels for drivers seeking enhanced braking performance. Constructed from high-carbon alloyed iron and subjected to Thermal Stability Profiling (TSP), these rotors are built to withstand the increased stress and heat generated during intense braking applications. The innovative T3 slot design contributes to consistent performance, while the patented Kangaroo Paw ventilation system, featuring 144 diamond and teardrop pillars, provides up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs. Key technical specifications include an outside diameter of 302.5 mm, a nominal and discard thickness of 24 mm, and an overall height of 45 mm. The rotor is a vented type with a slotted surface and has a 72 mm center hole diameter and 5 lug holes. This DBA42552S rotor is specifically designed for the 2004-2008 Mazda RX-8. Fitment notes indicate compatibility with Normal Suspension and Automatic Transmission for 2004-2005 models, and Normal Suspension for 2006-2008 models.
