DBA's 4x4 Survival Series T2 rotor provides all the benefits of DBA's Street Series direct replacement rotors with the added benefit of performance braking through the introduction of DBA's patented T2 slot design. The T2 slot design features precise CNC machined bi symmetrical slots, resulting in a quieter, more responsive and smoother brake pedal feel. The T2 slot increases the number of exit points, allowing friction dust and gases to escape and enhancing the pad bite. DBA's revolutionary universal slot design also eliminates the need for separate left and right slot designs seen in traditional rotor designs. We recommend the T2 slot design for more intensive braking applications. Features (Where Applicable): Kangaroo Paw 144 diamond and tear drop pillar ventilation system Increased surface area resulting in greater heat dissipation which minimises brake fade and increases braking effectiveness CBN (Cubic Boron Nitride) machine turned Reduced DTV (Disc thickness variation) and parallelism which provides less occurrence of brake shudder or brake pedal "judder".
