DBA DBA42208S 4000 Series T3 Slotted Performance Brake Rotor

The DBA DBA42208S 4000 Series T3 Slotted Brake Rotor is a direct replacement, single-piece performance brake rotor designed for drivers seeking upgraded braking performance beyond standard OE levels. Ideal for high-performance street vehicles, track cars, heavily laden 4x4s, and SUVs.

Patented T3 Slot Design:

Built on the foundations of DBA's T2 slot technology, the T3 design features additional precision CNC-machined tri-symmetrical curved slots that deliver a quieter, more responsive, and smoother brake pedal feel. The T3 slot pattern increases the number of exit points for brake pad friction dust and gases to escape, further increasing the consistency and effectiveness of every brake stop while minimizing the noise commonly associated with straight-slot rotor designs.

Advanced Materials and Manufacturing:

• Cast from XG-150 high carbon alloyed iron for superior strength and durability
• Thermal Stability Profiling (TSP) heat treatment realigns the microstructure of the iron at the atomic level, resulting in increased rotor stability, durability, and resistance to warping
• Patented Kangaroo Paw ventilation system implements 144 diamond and teardrop patterned pillars, achieving up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation and potential for pad knock and premature wear

Performance Features:

• Thermo-Graphic Heat Paint (TGHP) markings change color at specific temperature thresholds to assist with monitoring braking temperatures and rotor fatigue
• Universal symmetrical slot design eliminates the need for left and right specific rotors
• Painted non-friction areas prevent rust and enhance appearance
• Moisture-proof corrosion protection packaging
