DBA DBA4545XS 4000 Series XS Gold Drilled and Slotted Front Brake Rotor

The DBA DBA4545XS is a premium 4000 Series XS Gold performance brake rotor featuring a non-directional cross-drilled and slotted design with an attractive gold finish on the rotor hub. This front rotor combines enhanced aesthetics with serious braking performance, making it ideal for enthusiasts seeking both show-quality appearance and improved stopping power.

Advanced Cooling and Performance:

• Cross-drilled and slotted design increases exit points for brake pad friction dust and gases, resulting in more consistent braking performance
• Kangaroo Paw ventilation pattern with 144 diamond and teardrop pillars provides up to 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• Cast from XG-150 high carbon alloyed iron for superior heat handling and durability
• 270mm rotor diameter designed for front axle applications

Engineering Features:

• Thermal Stability Profiling (TSP) heat treatment process relieves internal stresses and optimizes rotor material for extreme braking conditions
• Thermographic heat paint markings change color at specific temperature thresholds to monitor braking temperatures and rotor fatigue
• Cubic Boron Nitride (CBN) machine turned finish minimizes disc thickness variation and premature pad wear
• Centre-split core castings enhance heat transfer and thermal efficiency
• Symmetrical drilling pattern allows universal left/right use
• Painted non-friction areas prevent rust and enhance appearance

The XS Gold variant offers similar performance benefits to DBA's renowned T3 slotted rotors while providing distinctive gold-hub styling that makes it a popular choice for show cars and performance street vehicles. Note that drilled rotor configurations are not recommended for heavy off-road or dedicated track day usage. Sold individually; two rotors required per vehicle.
