DBA DBA42996S 4000 Series T3 Slotted Front Brake Rotor with Kangaroo Paw Venting

The DBA DBA42996S is a front disc brake rotor from DBA's (Disc Brakes Australia) 4000 Series T3 Slotted lineup. Engineered as a direct-fit, single-piece replacement rotor, it is designed for drivers who demand braking performance above and beyond standard OE levels — whether on the street, at the track, or in club motorsport applications.

Key Features:

• T3 Tri-Symmetrical Slot Design: CNC-machined slots are precisely arranged in a tri-symmetrical pattern, delivering a quieter, more responsive, and smoother brake pedal feel while continuously de-glazing brake pads for consistent bite.
• Patented Kangaroo Paw Ventilation: 144 diamond and teardrop-shaped pillars replace conventional straight vanes, achieving up to a 30% increase in surface area and up to 20% improvement in cooling efficiency for superior heat dissipation under hard braking.
• XG-150 High Carbon Alloyed Iron: Cast from premium XG-150 grey iron alloy, specifically chosen for its enhanced thermal capacity, strength, and resistance to surface cracking under extreme braking loads.
• Thermal Stability Profiling (TSP): DBA's proprietary heat treatment process subjects each rotor to controlled heat cycles to relieve internal casting stresses, improving fatigue resistance, minimizing surface cracking, and reducing required break-in time.
• Thermo-Graphic Heat Paint (TGHP): Color-coded paint markings on the rotor's outer edge change color at specific temperature thresholds, allowing drivers to monitor peak rotor temperatures and optimize brake pad selection accordingly.
• Black High-Temperature Coating: Non-friction surfaces are treated with a black high-temperature coating to resist rust and enhance appearance throughout service life.
• CBN Machine-Turned Finish: Cubic Boron Nitride (CBN) machining minimizes disc thickness variation (DTV), reducing the potential for pad knock and premature wear.

The DBA42996S slots in place with no modifications required, making it an ideal upgrade for performance-minded drivers looking for a direct OE replacement with significantly enhanced heat handling, pad life, and braking consistency. Sold as a single rotor.
