Description
DBA 4000 Series discs are single-piece performance brake discs, cast from DBA’s XG150 high carbon alloyed iron for greater thermal capacity, reduced fade and a longer service life than standard replacement discs. Supplied as a pair (2 discs) for one axle.
The 4000 Series XD is a premium, direct-replacement single-piece performance brake disc designed for drivers seeking a significant braking upgrade above standard OE levels. The XD variant stands out with DBA’s exclusive non-directional cross-drilled and dimpled disc design. This advanced finish provides exceptional structural support compared to traditional drilling, offering enhanced cooling benefits, improved exit points for friction dust and gasses, and an aggressive, sporty aesthetic.
Key Features of the XD Finish
- Cross-Drilled & Dimpled Design: Superior heat dissipation and structural integrity, preventing premature warping and brake fade.
- Kangaroo Paw Ventilation: DBA’s patented vane design ensures up to 20% better heat dissipation than traditional straight-vane discs.
- Thermal Stability Profiling (TSP): Realignment of the iron microstructure through intense heat treatment cycles provides elevated durability.
- High Carbon Alloyed Iron: Ensures peak performance over extended periods under continuous extreme heat.
- Thermographic Heat Paint: Built-in markings change colour at specific temperature thresholds, allowing you to easily monitor braking temperatures.
Note: While the XD finish provides incredible street performance and styling, drilled disc configurations are not recommended for intensive, heavy off-road use or aggressive track day applications.
