DBA DBA4954S Series Slotted Brake Rotor - 4000 T3

The DBA DBA4954S is a high-performance single-piece slotted brake rotor from the acclaimed 4000 Series T3 lineup, designed for drivers seeking superior braking performance beyond standard OE levels. This rotor is ideal for street driving, track days, and motorsports applications where consistent, reliable braking is essential.

Advanced Materials and Construction:

• Cast from XG-150 high carbon alloyed iron for exceptional strength and heat resistance
• Thermal Stability Profiling (TSP) process subjects the rotor to controlled heat cycles, relieving internal stresses and maximizing thermal stability
• Black high-temperature coating on non-friction areas for corrosion protection and appearance
• CBN (Cubic Boron Nitride) machined finish minimizes disc thickness variation and premature pad wear

Patented T3 Slot Design:

• Tri-symmetrical CNC machined slots provide multiple exit points for brake dust and gases
• Universal bi-directional design eliminates the need for left/right specific rotors
• Delivers quieter operation, more responsive braking, and smoother pedal feel compared to traditional slotted designs
• Continuously de-glazes brake pads for consistent performance and reduced fade

Kangaroo Paw Ventilation Technology:

• Features 144 diamond and teardrop patterned pillars for optimal cooling
• Achieves up to 30% increase in surface area compared to straight vane designs
• Provides 20% improvement in cooling efficiency for better heat dissipation
• Center-split core casting enhances heat transfer and thermal efficiency

Additional Features:

• Thermo-Graphic heat paint markings change color at specific temperatures to monitor rotor temperatures and detect potential fatigue
• Direct replacement design—bolts on with no modifications required
• Rated for severe motorsports use while maintaining excellent street manners
• Sold individually
