DBA DBA42074 4000 Series HD Rear Disc Brake Rotor 360mm

The DBA DBA42074 is a 4000 Series HD rear disc brake rotor engineered for drivers who demand performance braking beyond standard OE levels while maintaining a clean, OE-style appearance. The 4000 Series HD variant features a smooth OE-style rotor finish, popular for drivers seeking the benefits of a 4000 Series rotor while requiring an OE-style look, such as in controlled race divisions.

Key Features:

• High Carbon Alloyed Iron Construction: 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.
• Kangaroo Paw Ventilation: 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.
• CBN Machine-Turned Finish: A Cubic Boron Nitride (CBN) machine-turned finish minimises disc thickness variation and the potential for pad "knock" and resulting premature wear.
• Thermographic Heat Paint Markings: Paint markings change colour at specific temperature thresholds to assist with the monitoring of braking temperatures and rotor fatigue.
• Rust-Resistant Coating: Non-friction areas are painted to prevent rust and enhance appearance.
• Direct OE Replacement: 4000 Series disc brake rotors are a direct replacement single-piece brake rotor, designed for drivers seeking upgraded performance braking above and beyond standard OE levels.
• Rotor Diameter: 360mm | Axle Position: Rear | Quantity Per Car: 2

With 40+ years of experience manufacturing brake rotors in Australia, all DBA disc brake rotors are a direct replacement, meaning no modification is required. 4000 Series rotors are recommended for performance street cars, heavily laden utes or 4WDs, and for towing.
