DBA's direct replacement brake rotors are designed for drivers seeking upgraded performance braking above and beyond standard OE levels. Its performance series are cast from high carbon alloyed iron and undergo Thermal Stability Profiling (TSP), allowing DBA's metallurgy to handle increased stress and heat generated under intense braking applications, time and time again.
