42961XS Rear Performance Street Brake Rotor

The DBA DBA42961XS is a high-performance, direct replacement rear brake rotor engineered for drivers seeking braking capabilities beyond standard OE levels. This 4000 Series XS rotor utilizes DBA's advanced technology and premium materials, including proprietary XG-150 high carbon alloyed iron, which is heat-treated for enhanced heat capacity and durability under constant thermal stress. The rotor's unique cross-drilled and slotted design serves multiple purposes: it improves braking power and consistency while also increasing the number of out-gassing exit points to allow brake pad friction gasses to escape efficiently. The Kangaroo Paw ventilation system, featuring 144 diamond and teardrop pillars, further enhances cooling and extends the life of both the brake pads and the rotor, thereby reducing potential damage and expenses. For added convenience and safety, the DBA42961XS incorporates thermographic temperature monitoring paint markings. These markings help drivers keep track of rotor fatigue, indicating when it may be time to replace the rotors or file warranty claims. The non-friction surfaces are treated with paint to prevent rusting, maintaining the rotor's appearance and integrity. This rotor is sold individually and is designed as a perfect direct replacement for specific vehicle applications. This specific DBA42961XS rotor is designed for the rear of the 2006-2007 Mazda 6 Mazdaspeed models.
