With over four decades of innovation under their belt, backed by intensive research and development, DBA has positioned itself as a world leader in the extremely competitive marketplace of OE and aftermarket disc brake rotor solutions. Whether you are after some basic replacement rotors for your standard passenger vehicle, 4x4 offroad or commercial vehicle, weekend toy or a hard-tuned track car, DBA has a set of rotors to enhance your vehicle's braking performance at a price and performance level to meet your unique requirements.
5000 Series rotors can be improved with the XD cross-drilled and dimpled design, having undergone additional CNC machining to yield 84 cross-drilled holes, and 36 dimples, to allow maximum heat transfer, along with dust and gas removal. This is achieved whilst minimising the propensity to crack often seen in drilled rotors.
The 5000 Series take the same excellent XG-150 cast iron alloy used in the Street Series, and are further enhanced with TSP - Thermal Stability Profiling. This additional heat treatment process takes detail down to the atomic level, aligning the grain structure the compound to produce a uniform material. This is then combined with an aerospace grade T6061-T6 aluminium alloy centre hat, bolted together with NAS specification hardware. The move to an aluminium centre hat reduces sprung weight and prevents heat transfer from the rotor to the hub, realising greater performance and reducing thermal impact on the wheel bearings and hub. The result of this is the 5000 Series HD, a superior quality rotor able to withstand greater levels of heat, for a longer service life considerable resistance to warping from excessive heat events. Standard on every 5000 Series rotor is the inclusion of Thermographic Heat Paint Markings, allowing the user to identify peak braking temperatures in extreme conditions. 5000 Series rotors are recommended for high performance track cars, heavily laden ute's and 4WD's, and for towing large trailers or caravans.
