Ideal for enthusiasts looking for an upgrade over stock rotors.

Premium non-directional cross-drilled and slotted design of DBA brake rotors increases the number of outgassing exit points allowing more brake pad friction gasses to escape through.

Brake rotors from DBA Street Series feature with "Kangaroo Paw€ť €“ 144 diamond and tear drop pillar ventilation system. Increased surface area results in greater heat dissipation and thus minimises brake fade and increases braking effectiveness of disc brake. CBN (Cubic Boron Nitride) machine turned reduces DTV (Disc thickness variation) and parallelism which brings less occurrence of brake shudder or brake pedal €˜judder€™.

While providing a similar performance benefit to the T3 slot, the 4000 XS Series is a popular alternative for open wheel and show cars. We recommend the T3 slot design for more intensive braking applications.
