DBA DBA4749XS 4000 Series XS Gold Cross-Drilled Slotted Rear Brake Rotor

The DBA DBA4749XS is a premium 4000 Series XS Gold performance brake rotor designed for drivers seeking upgraded braking performance beyond standard OE levels. This rear solid rotor features a non-directional cross-drilled and slotted pattern combined with an attractive gold finish on the rotor hub, delivering both enhanced performance and distinctive styling.

Advanced Materials and Engineering:

• Constructed from XG-150 high-carbon alloyed iron for superior strength and heat resistance
• Thermal Stability Profiling (TSP) heat treatment realigns the microstructure of the iron, minimizing warping and cracking while extending rotor service life
• Patented Kangaroo Paw ventilation system with 144 diamond and teardrop patterned pillars achieves up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Center-split core castings provide increased heat transfer and thermal efficiency

Performance Features:

• Non-directional cross-drilled and slotted XS pattern increases the number of exit points for brake pad friction dust and gases to escape, improving consistency and effectiveness of every brake stop
• Universal design eliminates the need for separate left and right rotors
• Cubic Boron Nitride (CBN) machine-turned finish minimizes disc thickness variation and reduces potential for pad knock and premature wear
• Thermographic heat paint markings permanently change color at specific temperature thresholds, allowing drivers to monitor peak braking temperatures and rotor fatigue
• Protective gold paint on all non-friction surfaces prevents rust and enhances appearance
