DBA DBA4456 4000 Series Standard Kangaroo Paw Front Brake Rotor

The DBA DBA4456 is a 4000 Series Standard (smooth-face) front disc brake rotor featuring DBA's patented Kangaroo Paw (KP) ventilation system. Built as a direct, single-piece OE-replacement rotor, it delivers measurably improved braking performance over the factory unit without requiring caliper relocation or bracket modifications.

Manufactured by Disc Brakes Australia (DBA), the 4000 Series is cast from high-carbon alloyed iron and subjected to DBA's proprietary Thermal Stability Profiling (TSP) process — a controlled heat-cycling treatment that relieves internal manufacturing stresses, improves fatigue resistance, and maximizes thermal stability under repeated heavy braking.

The Kangaroo Paw vane design uses 144 diamond- and teardrop-patterned internal pillars to achieve up to a 30% increase in internal surface area and up to a 20% improvement in cooling efficiency compared to conventional straight-vane rotors. This significantly reduces heat buildup, brake fade, rotor warpage, and hot-spotting during demanding use.

Key Features:

• Direct OE replacement — no caliper relocation or additional hardware required
• Single-piece construction for strength and reliability
• High-carbon alloyed iron casting for superior heat management
• Patented Kangaroo Paw (KP) ventilation: 144 diamond and teardrop pillars
• Up to 30% more internal surface area vs. straight-vane designs
• Up to 20% better cooling efficiency vs. traditional vented rotors
• Thermal Stability Profiling (TSP) for reduced metal fatigue and improved rotor life
• Smooth OE-style friction face — compatible with all standard brake pad compounds
• Black high-temperature corrosion-resistant coating on non-friction surfaces
• MTO (Made to Order) product

The DBA4456 is an ideal upgrade for drivers who want reliable, consistent stopping power beyond OEM levels while retaining an OE-style rotor appearance. Sold individually.
