DBA 4000 Series T3 Slotted Brake Rotors
*Black 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).
Expert Opinion
DBA 4000 T3 Rotors are one of the highest quality rotors on the market today. Rated for severe motorsports use, these rotors will take a thrashing without missing a beat. On the track, these rotors have no problem handling the heat and high friction characteristics of even the most aggressive race pads. Pair with Hawk SuperDuty brake Pads on heavy pickups and SUV's where braking has been an issue in the past. On average, these rotors will last 3x longer than most other rotors on the market.
DBA 4000 Series T3 Rotor Features
- XG-150 High Carbon Alloyed Iron

- Thermo-graphic paint markings (THGP)
- Direct replacement suitability
- Moisture proof corrosion protection packaging
Thermal Graphic Heat Paint
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.
Thermal Stability Profiling
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.
- Improved fatigue resistance to minimize surface cracking
- Reduced rotor fatigue during prolonged heavy braking
- Quick replacement, minimal "bedding-in" of rotors
