2-Piece T3 Slotted Brake Rotor

The DBA DBA52218BLKS is a two-piece T3 slotted brake rotor from DBA's 5000 Series, engineered for drivers seeking upgraded performance braking beyond standard OE levels. This rotor is constructed from high-carbon alloyed iron that undergoes Thermal Stability Profiling (TSP) to handle increased stress and heat from intense braking applications. The rotor features DBA's patented Kangaroo Paw ventilation system, incorporating 144 diamond and teardrop-shaped pillars. This design provides up to a 30% increase in surface area and a 20% improvement in cooling efficiency compared to traditional straight vane designs. The T3 slot profile is designed to help remove dust and gases, enhancing pedal feel and preventing premature wear. Key technical specifications include an outside diameter of 320mm, a nominal thickness of 32mm, and a vented rotor type. The ultra-lightweight 6061 T6 aviation aluminum center hat is anodized to resist rust and minimize hub heat, contributing to better vehicle control. The rotor's microstructure is realigned during heat treatment for enhanced stability and longevity. Paint markings on the rotor change color at varying temperature levels, providing a visual indicator of rotor fatigue. This rotor is specifically designed as a direct replacement for the front of the 2003-2006 Mitsubishi Lancer Evolution models. Fitment compatibility can vary, and this rotor is specified for the Evolution trim, including variations like Evolution MR, Evolution RS, and Evolution SE across the 2003-2006 model years. The buybrakes.com site notes that for 2006 Mitsubishi Lancer, this may apply to Evolution Models; Rear Disc, which may indicate a potential difference in rear applications or a typo. The Stillen site lists it for 2003-2006 Mitsubishi Lancer Evolution (Front).
