DBA DBA52525.1XS 5000 Series 2-Piece Drilled & Slotted Brake Disc Ring

The DBA DBA52525.1XS is a 5000 Series two-piece composite brake disc ring from Disc Brakes Australia, engineered for high-performance and heavy-duty braking applications. Designed as a direct replacement rotor ring, it pairs with a compatible hat/bell to form a complete two-piece rotor assembly, offering superior heat dissipation and reduced unsprung weight compared to traditional one-piece rotors.

Building on the proven foundation of DBA's 4000 Series, the 5000 Series disc ring features a drilled and slotted surface pattern that works together to evacuate heat, gas, and debris from the braking surface. The cross-drilled holes reduce rotor mass and improve cooling airflow, while the slots continuously clean and refresh the brake pad surface for consistent, fade-resistant stopping power.

Key Features:

• Two-Piece Composite Design: Disc ring separates from the hat for reduced weight and improved thermal management
• Drilled & Slotted Surface: Cross-drilled holes and precision slots for maximum heat and gas evacuation
• High-Quality Metallurgy: Manufactured from premium-grade iron alloy for long service life under demanding conditions
• Direct Replacement Fit: Engineered to OEM specifications for straightforward installation
• 5000 Series XS Spec: The XS designation indicates an extra-slot pattern for enhanced pad bite and rotor sweep
• Corrosion-Resistant Finish: Protective coating on non-braking surfaces to resist rust and corrosion

DBA's 5000 Series is the ideal upgrade for performance driving, towing, and track-day use where consistent braking performance under sustained heat and stress is critical. As a disc ring only, this part is intended for use with a two-piece rotor hat assembly.
