DBA DBA42096 Series HD Brake Disc Rotor - 4000

The DBA DBA42096 is a 4000 Series HD (Heavy Duty) brake disc rotor from Disc Brakes Australia — a direct-fit, single-piece performance upgrade designed for drivers who want braking performance beyond standard OE levels while retaining a clean, factory-style appearance.

The 4000 Series HD variant features a smooth OE-style rotor finish, making it popular for drivers who want the engineering benefits of DBA's 4000 Series platform without a slotted or drilled aesthetic — ideal for controlled race divisions or daily drivers seeking a stock look with upgraded performance.

Key Features:

• Kangaroo Paw Vane Design: 144 diamond and teardrop-patterned internal pillars deliver up to 30% more surface area and 20% improved cooling efficiency versus traditional straight-vane rotors
• High Carbon Alloy Iron Construction: Cast from XG-150 high carbon alloyed iron for superior strength, reduced noise, and excellent heat absorption
• Thermal Stability Profiling (TSP): DBA's proprietary heat treatment process relieves internal casting stresses and realigns the iron's microstructure for maximum thermal stability and reduced metal fatigue under demanding conditions
• Smooth OE-Style Finish: Clean, unslotted rotor surface suits stock-look requirements while delivering 4000 Series performance
• Rust-Resistant Paint: Non-friction areas are painted to prevent corrosion and improve appearance
• Temperature Monitoring Paint Markings: Heat-sensitive paint markings change color at specific temperature thresholds to help monitor braking temperatures and rotor fatigue
• Micron-Level Machined Surface: Friction surfaces are precision-machined for even pad bed-in, reduced wear, and consistent performance across a wide temperature range
• Centre Split Core Casting: Improves heat transfer and overall thermal efficiency

The DBA42096 is a sold-individually (single rotor) direct replacement disc brake rotor engineered to deliver upgraded stopping power with a bolt-on fit. DBA backs this rotor with a 12-month / 12,000-mile warranty against defects in materials and workmanship.
