DBA DBA4901S 4000 Series T3 Slotted Performance Brake Rotor

The DBA 4000 Series T3 Slotted Brake Rotor is a direct replacement single-piece brake rotor designed for drivers seeking upgraded performance braking above and beyond standard OE levels. Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), DBA's metallurgy is able to handle the increased stress and heat generated under intense braking applications, time and time again.

Advanced T3 Slot Design:

Built on the foundations of DBA's T2 slot, the T3 slot design features additional, precise, CNC machined tri-symmetrical slots, resulting in an even quieter, more responsive and smoother brake pedal feel. The T3 adds several more gas scavenging slots to the rotor face, going from 32 slots in the T2 to 48 slots in the T3. The tri-symmetrical curved slots dampen the vibration harmonics or noise, that's commonly associated with traditional straight slot rotor designs.

Patented Kangaroo Paw Ventilation:

Featuring DBA's patented Kangaroo Paw ventilation that implements a series of 144 diamond and teardrop patterned pillars, DBA achieves up to a 30% increase in surface area and 20% improvement in cooling efficiency as compared to a traditional straight vane design.

Key Features:

• CBN (Cubic Boron Nitride) machine turned finish, minimizing disc thickness variation and the potential for pad knock and resulting premature wear
• Thermo-Graphic Heat Paint (TGHP) markings of Green, Orange and Red change color once your rotor reaches predetermined critical temperature thresholds
• Symmetrical slotting for universal left/right use
• Painted non-friction areas to prevent rust and enhance appearance
• Rated for severe motorsports use
• On average, these rotors will last 3x longer than most other rotors on the market
