T3 Slotted Brake Rotor

The DBA DBA4478S is a high-performance, direct-replacement T3 slotted brake rotor from the 4000 Series, engineered to significantly upgrade your vehicle's braking capabilities beyond standard Original Equipment (OE) specifications. Constructed from XG150 High Carbon Alloy Iron, this rotor is heat-treated and designed to withstand the increased stress and heat generated during demanding braking applications. Its construction helps to reduce warping and cracking, thereby prolonging rotor life. This advanced ventilation is crucial for reducing brake fade and enhancing braking efficacy, especially during track day or towing scenarios. DBA's signature Tri-symmetrical curve slots are implemented to decrease vibration and noise, contributing to a quieter and smoother brake pedal feel. These slots also act as out-gassing exit locations for brake pad friction gasses, which improves brake stop uniformity and overall performance. A universal slot design is utilized, eliminating the need for specific left and right discs, simplifying installation. For added convenience and longevity, the rotor includes built-in temperature monitoring to indicate peak braking temperatures and features protective paint on its non-friction areas to minimize rust formation. This brake rotor is recommended for performance use and is suitable for driving qualifiers such as Extreme & Fleet Duty, Towing-Oversized Tires, Performance Street, and Street & Track Events. It boasts a 5/5 rating for stopping power and a 1/5 for noise level, with performance over stock rated at 4 - Track Day/Towing.
