Front Brake Rotor

The Stillen DBA3550E is a front brake rotor from Disc Brakes Australia (DBA), designed as a direct replacement for drivers seeking performance braking upgrades beyond standard OE levels. These Street Series T2 rotors are cast from high carbon alloyed iron and treated with Thermal Stability Profiling (TSP) to withstand the significant stress and heat generated during intense braking applications. DBA's innovative design incorporates their patented Kangaroo Paw ventilation system. This unique design utilizes 144 diamond and teardrop-shaped pillars to achieve up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane rotors. This enhanced cooling capability helps prevent brake fade and maintain consistent stopping power. With a 320mm outside diameter and a vented rotor type, the DBA3550E offers robust performance. The rotor has a nominal thickness of 28mm and a discard thickness of 28mm, with 5 lug holes and a smooth surface type. It also features DBA's En-Shield coating, a chromium-free, zinc-aluminium derived, water-based heated treatment that provides protection against rust and corrosion on the rotor surface. This specific rotor (DBA3550E) is compatible with the following applications: 2019-2021 Mazda 6 (USA Market), 2022 Mazda CX-5, 2016, 2018, 2021, and 2023 Mazda CX-9.
