Overview

The DBA DBA42163S is a front disc brake rotor designed for performance applications. It features DBA's patented T3 bi-directional slot design, which increases the number of out-gassing exit locations for brake pad friction gasses, improving brake stop uniformity and efficacy. The rotor is constructed from XG150 High Carbon Alloy Iron to reduce warping and cracking, and has a coated finish for rust protection on non-friction areas. This is a direct replacement rotor for upgraded braking performance above OE levels.
Show original supplier description
The DBA DBA42163S is a performance-oriented, direct-replacement, single-piece brake rotor engineered to provide braking capabilities exceeding standard OE levels. It incorporates DBA's patented T3 bi-directional slot design, which features tri-symmetrical curve slots that decrease vibration and noise for a quieter, smoother pedal feel. This design also increases the number of out-gassing exit locations, improving brake stop uniformity and efficacy. Constructed from XG150 High Carbon Alloy Iron, this rotor is treated to minimize warping and cracking, thereby prolonging its lifespan. The Kangaroo Paw ventilation system, with its 144 diamond and tear-drop patterned pillars, significantly reduces brake fade and enhances cooling efficiency compared to traditional vane designs. Additionally, the rotor includes temperature monitoring capabilities to indicate peak braking temperatures, and a protective coating on non-friction areas prevents rust formation. This rotor is recommended for a variety of driving conditions, including Extreme & Fleet Duty, Towing-Oversized Tires, Performance Street, and Street & Track Events. It is specifically designed as a front brake rotor for the 2017 Ford Fiesta.
