Description

For the spirited driver or performance modified street vehicle, the XS cross-drilled and slotted design is the best option.  The DBA XS design is available only for 4000 and 5000 series rotors. 

This is a premium (advanced) cross-drilled and slotted pattern providing improved braking performance for street use only.

SPECIAL NOTE:  The XS design is for street use only.  Available for a limited range of vehicle models. 

 

The holes remain effective in combating ‘out-gassing’ for the whole life of the disc. As with slots, the pattern is unique for each rotor type, typically we have between 24 and 36 holes per disc face, each with a diameter of 5mm. To counter the tendency for cracks to form between holes, we previously put just one hole per vane on ventilated discs to ensure the walls between the vanes would act as a strengthening barrier between the holes. The increasing adoption of the patented Kangaroo Paw ventilation system on DBA Street Series rotors, however, has made this more complex.

The Kangaroo Paw system doesn’t use traditional vanes - it uses a series of diamond shaped pillars to promote greater airflow. The holes now need to be positioned next to these pillars. In a manufacturing sense this is more complex, but from a buyer’s point of view it gives a disc that is stronger as well as better cooled. Each hole is chamfered or ‘radiused’ around its opening to reduce pad abrasion and provide a smooth transition between hole and friction area.
