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.
4000 Series disc brake discs are a direct replacement single piece brake disc, designed for drivers seeking upgraded braking above and beyond standard OE levels.
4000 Series HD features a smooth OE style disc finish, popular for drivers looking for the benefits of a 4000 Series disc but requiring an OE style look, such as controlled race divisions.
Cast from high carbon alloyed iron and undergoing Thermal Stability Profiling, DBA’s metallurgy can handle the increased stress and heat generated under intense braking applications, time and time again.
Featuring DBA’s Kangaroo Paw ventilation that implements a series of 144 diamond and teardrop patterned pillars, DBA achieves up to a 30% increase in surface area and 20% improvement in cooling efficiency (as compared to a traditional straight vane design).
