Description

The DBA T3 4000 Series is a performance brake rotor designed as a direct replacement. It features DBA's patented T3 bi-directional slot design, which increases the number of points for brake dust and gases to escape, enhancing stopping consistency and effectiveness. The universal slot design eliminates the need for separate left and right rotors.
