DBA DBA42951 4000 Series HD Rear Disc Brake Rotor 280mm

The DBA DBA42951 is a 4000 Series HD rear disc brake rotor engineered by Disc Brakes Australia (DBA) as a direct-fit, single-piece performance upgrade over OE braking systems. Measuring 280mm in diameter with a 5-bolt mounting pattern and 72mm centering bore, this rotor delivers meaningful performance gains while retaining a clean, smooth OE-style appearance ideal for controlled race divisions or drivers who prefer a stock look.

Key Features:

• XG-150 High Carbon Alloyed Iron Construction — Cast from premium XG-150 grey iron for superior strength, heat resistance, and long-term durability under intense braking conditions
• Thermal Stability Profiling (TSP) — DBA's proprietary heat treatment process subjects each rotor to controlled thermal cycles to relieve internal manufacturing stresses, maximizing stability and reducing metal fatigue in high-demand applications
• Kangaroo Paw Ventilation — Features 144 diamond and teardrop patterned internal pillars delivering up to a 30% increase in surface area and up to 20% improvement in cooling efficiency over traditional straight-vane designs
• Thermographic Heat Paint Markings — Color-changing paint on non-friction surfaces alerts users to critical temperature thresholds, helping monitor rotor health and braking temperatures
• Smooth HD Finish — OE-style surface finish with no slots or cross-drilling, satisfying regulations in controlled racing classes while still benefiting from all 4000 Series performance enhancements
• Painted Non-Friction Areas — Rust-resistant coating on hat and non-contact surfaces protects appearance and longevity
• Rear Axle Application — Single rotor; two required per vehicle for a complete rear axle replacement

The DBA 4000 Series HD is the ideal choice for performance street driving, sport compacts, towing applications, and controlled motorsport classes where a slotted or drilled rotor is not permitted. Sold individually.
