DBA DBA42698 Series HD Disc Brake Rotor - 4000 350mm

The DBA DBA42698 is a 4000 Series HD disc brake rotor engineered as a direct-fit, single-piece performance upgrade over standard OE braking. Designed for drivers seeking upgraded performance braking above and beyond standard OE levels, this rotor delivers measurable improvements in stopping power, heat management, and service life.

Cast from high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), DBA's metallurgy can handle the increased stress and heat generated under intense braking applications, time and time again.

The 4000 Series HD variant features a smooth OE style rotor finish, popular for drivers looking for the benefits of a 4000 Series rotor but requiring an OE style look, such as controlled race divisions.

Key Features:

• DBA's Kangaroo Paw ventilation implements a series of 144 diamond and teardrop patterned pillars, achieving up to a 30% increase in surface area and 20% improvement in cooling efficiency compared to a traditional straight vane design.
• Symmetrical slots and/or chamfered drill holes facilitate the exit of friction dust and gases, for a quieter and more responsive pedal feel.
• CBN (Cubic Boron Nitride) machine turned finish minimizes disc thickness variation and the potential for pad "knock" and resulting premature wear.
• Thermographic Heat Paint Markings are included as standard on every 4000 Series rotor, allowing the user to identify peak braking temperatures in extreme conditions.
• Painted non-friction areas prevent rust and enhance appearance.
• Symmetrical slotting for universal left/right fitment.
• Manufactured to QS-9000 quality standards using premium grade materials with a high iron content and dense metal matrix, resulting in long wear and safe, consistent stopping power.

4000 Series rotors are recommended for performance street cars, heavily laden utes or 4WDs, and for towing. The DBA42698 is sold as a single rotor.
