DBA DBA42653S-10 4000 Series T3 Slotted Disc Brake Rotor

The DBA DBA42653S-10 is a 4000 Series T3 slotted disc brake rotor engineered as a direct-fit, single-piece performance upgrade over OEM brake rotors. Featuring DBA's patented T3 bi-directional slot design, this rotor delivers improved stopping power, reduced brake fade, and a quieter, more responsive pedal feel compared to standard replacement rotors.

Key Features:

• T3 Tri-Symmetrical Slotting: CNC-machined tri-symmetrical slots increase exit points for friction dust and gases, enhancing braking consistency and pad bite
• Kangaroo Paw Ventilation: Patented internal vane design with 144 diamond and teardrop-patterned pillars delivers up to 20% greater cooling efficiency over conventional straight-vane rotors
• XG-150 High-Carbon Alloyed Iron: Premium iron formulation provides superior resistance to heat stress, warping, and hot-spotting
• Thermal Stability Profiling (TSP): Proprietary heat treatment realigns the microstructure of the iron for increased rotor stability and long-term durability
• Thermographic Heat Paint (THGP): Paint markings on the rotor edge change color at specific temperature thresholds, enabling easy monitoring of braking temperatures and rotor fatigue
• CBN Machine-Turned Finish: Cubic Boron Nitride finishing minimizes disc thickness variation, reducing the potential for pad knock and premature wear
• Bi-Directional Design: Symmetrical slotting allows universal left/right fitment — no separate left and right rotors required
• Corrosion Protection: Non-friction areas are painted to prevent rust and maintain appearance
• Black Finish (-10): The -10 suffix denotes DBA's black non-friction area coating for a clean, stealthy appearance
• Direct OEM Replacement: Bolt-on fitment with no mechanical modifications required

The DBA 4000 Series T3 is DBA's premier single-piece performance brake rotor, ideal for enthusiast street driving and high-performance applications where consistent, fade-free braking is essential. Sold individually; it is recommended to replace rotors as a matched axle pair.
