DBA 4000 Series XS 290mm Front Vented Rotor

The Stillen DBA 4000 Series XS brake rotor is engineered by Disc Brakes Australia (DBA) to provide performance braking capabilities that exceed standard Original Equipment (OE) levels. Designed as a direct replacement, these rotors are constructed from high-carbon alloyed iron and utilize Thermal Stability Profiling (TSP) to ensure they can withstand the elevated stress and heat generated during demanding braking applications. This particular rotor, the DBA42959XS, is a front rotor featuring a vented design. It boasts a 290 mm outside diameter and a cross-drilled and slotted surface for enhanced performance. A key innovation is DBA's patented Kangaroo Paw ventilation system, which incorporates 144 diamond and teardrop pillars. This design contributes to a significant increase in surface area and a substantial improvement in cooling efficiency compared to traditional straight vane designs. Technical specifications for the DBA42959XS include a 72 mm center hole diameter, a discard thickness of 22 mm, a nominal thickness of 22 mm, and an overall height of 45.1 mm. The rotor is designed with 5 lug holes. This DBA 4000 Series XS brake rotor is compatible with the 2006-2011 Mazda MX-5 Miata and also the 2013 Mazda MX-5 Miata.
