| Feature Description | Advantage | Benefit |
 Kangaroo Paw – 144 diamond and tear drop pillar ventilation system |
Increased surface area resulting in greater heat dissipation | Minimises brake fade and increases braking effectiveness |
| Increased surface area resulting in greater heat dissipation | Prolongs service life for both pads and rotors. Reduces mechanical damage and associated costs | |
 XG150 High Carbon Alloyed Iron |
An increase in thermal capacity property allows the rotor to handle constant extremes of heat over extended periods of time | Minimises warping and cracking and prolongs the service life of the rotor |
 Paint protection on non-friction areas |
Reduces corrosion | Stops any unsightly rust formation |
| Enhances appearance | Adds value to the product | |
 CBN (Cubic Boron Nitride) machine turned |
Reduced DTV (Disc thickness variation) and parallelism | Less occurrence of brake shudder or brake pedal |
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” – 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.
