*Gold High Temperature Coating
DBA (Disc Brakes Australia) 4000 Rotors are a direct replacement single-piece brake rotor, designed for drivers seeking upgraded performance braking above and beyond standard OE levels. Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), DBA’s metallurgy is able to handle the increased stress and heat generated under intense braking applications, time and time again. Featuring DBA’s patented 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)
DBA 4000 XS Rotors are one of the highest quality cross-drilled rotors on the market today. Not as durable as the T3 version because of the cross-drilled holes. The XS version fits the bill when you want a high quality rotor and the look of a cross-drilling. The XS version is not recommended for motorsports usage, but is more than capable for high performance street use. On average, these rotors will last mush longer than most other rotors on the market.
Thermal Stability Profiling (TSP), is a DBA proprietary process, developed for use with all 4000 and 5000 Series high carbon disc rotors. Under the TSP process, XG-150 grey iron is subjected to prolonged heat cycles under strictly controlled conditions, to relieve any internal stresses sustained from the manufacturing processes. This ensures maximum thermal stability and reduced metal fatigue in extremely high demanding applications. DBA’s comprehensive materials testing both on the race track and in computer simulations has enabled the development of this temperature cycling process to optimize the disc rotor material prior to fitting on the vehicle.
DBA’s patented Thermo-Graphic Heat Paint (TGHP) markings are a standard feature on all DBA 4000 and 5000 Series disc rotors. The TGHP paint stripes of Green, Orange and Red will change color once your DBA rotor reaches predetermined critical temperature thresholds. Driver’s can monitor peak rotor temperatures to better understand the effects of their driving style and make informed choices in pad selection or whether their driving style is best for the application. TGHP color coding is incorporated with DBA’s range of Performance Pads, with the Performance Pads color coded to the heat thresholds. When your TGHP stripes change color, you should ensure you have the right DBA pads to match.

Cleaning a disc rotor correctly will often eliminate any issues with squeal, runout (DTV) and pad contamination. Most disc rotors have a protective coating applied post production to avoid any corrosion during storage. It’s a simple process that can be done in less than a minute.
