DBA DBA42312S 4000 Series T3 Slotted Brake Rotor

The DBA DBA42312S is a 4000 Series T3 Slotted Brake Disc engineered for demanding on- and off-road performance. Designed with DBA's proprietary T3 triple-slot pattern, this rotor improves bite, reduces brake fade, and efficiently evacuates heat, dust, and gases from the braking surface — keeping your stopping power consistent under heavy use.

DBA's 4000 Series rotors are built for drivers who demand more than factory-spec performance. The slotted design helps prevent glazing on brake pads, extends pad life, and provides a more progressive, confident brake feel whether you're on the highway or tackling rugged terrain.

Key Features:

• T3 Triple-Slot Pattern: DBA's unique three-slot configuration for superior heat and gas evacuation
• High-Carbon Grey Iron Construction: Provides excellent thermal capacity and rotor longevity
• Geomet Coating: Corrosion-resistant finish on the non-swept areas helps prevent rust and extend service life
• Precision Machined: Tight tolerances ensure minimal runout and vibration-free braking
• 4x4/SUV Duty Rated: Suited for light truck, 4x4, and SUV applications including off-road use
• OEM-Style Fitment: Direct bolt-on replacement requiring no modifications

The DBA42312S is the front rotor application in this fitment range. DBA is an Australian brake specialist with decades of motorsport and heavy-duty engineering heritage, making the 4000 Series a trusted upgrade for performance and 4x4 enthusiasts worldwide.
