4000 Series T3 Front Brake Rotor

The DBA DBA42124S is a 4000 Series T3 brake rotor from Disc Brakes Australia, engineered for drivers seeking performance braking that exceeds standard OE levels. This rotor is constructed from high-carbon alloyed iron and has undergone Thermal Stability Profiling (TSP) to withstand the increased stress and heat generated during intense braking applications. The Tri-symmetrical slotting design on this rotor not only decreases vibration and noise for a quieter brake pedal feel but also increases out-gassing exit locations for brake pad friction gasses, improving brake stop uniformity and efficacy. The universal slot design eliminates the need for left and right specific discs, and the high-carbon alloy iron reduces warping and cracking, prolonging rotor life. Temperature monitoring indicators are integrated to show the driver peak braking temperatures, and a protective coating on non-friction areas helps prevent rust formation. This performance rotor is recommended for driving qualifiers such as Extreme & Fleet Duty, Towing-Oversized Tires, Performance Street, and Street & Track Events. The DBA42124S is a vented rotor with an outside diameter of 355mm and a height of 47mm, designed as a direct replacement for the front of various Ford Mustang models, including the 2007-2010 models (specifically Shelby GT500, Shelby GT500KR for 2007-2009, and Shelby GT500 for 2010), and the 2013 Mustang (Boss 302 / GT with performance brakes, either automatic or manual transmission).
