DBA DBA3451E Rear Street Series En-Shield HC Brake Rotor 338mm

The DBA DBA3451E is a rear Street Series En-Shield Hybrid Composite (HC) disc brake rotor featuring a 338mm diameter. Engineered by Disc Brakes Australia — a globally recognised braking specialist with over 40 years of experience — this rotor delivers OE-level performance with enhanced corrosion resistance for daily driving confidence.

En-Shield Corrosion Protection:

DBA's En-Shield coating is a unique chromium-free, zinc-aluminium derived, water-based treatment that is applied to the entire rotor surface and baked on. This process protects against rust and environmental corrosion without introducing any impurities to the brake pad friction surface, eliminating the need for pre-installation cleaning.

Hybrid Composite (HC) Two-Piece Construction:

The DBA3451E utilises DBA's HC two-piece design, combining a cast iron braking surface (disc ring) with an aluminium or steel hat, permanently bonded by rivets or co-casting. This construction may reduce overall rotor weight by up to 15% compared to a conventional one-piece rotor without compromising braking performance.

Key Features:

• 338mm rotor diameter — rear axle fitment, 2 per vehicle
• En-Shield coating — chromium-free, zinc-aluminium baked-on protection against rust and corrosion
• Hybrid Composite (HC) design — up to 15% lighter than conventional one-piece rotors
• Kangaroo Paw vane design — provides up to 20% better heat dissipation for increased braking effectiveness and prolonged brake life
• CBN (Cubic Boron Nitride) machine-turned finish — minimises disc thickness variation, reducing the potential for pad knock and premature wear
• Centre-split core castings — increased heat transfer and thermal efficiency
• Direct OE replacement — no modifications required for installation

The Street Series is the ideal choice for daily drivers, light commercial vehicles, and SUVs seeking an OE-quality replacement rotor built to the highest manufacturing standards.
