DBA DBA42602BLKXS 4000 Series Drilled and Slotted Brake Rotor with Kangaroo Paw Venting

The DBA 4000 Series XS brake rotor is a direct replacement single-piece performance rotor designed for drivers seeking upgraded braking performance beyond standard OE levels. This premium rotor combines advanced metallurgy with innovative ventilation technology for exceptional heat management and braking consistency.

Advanced Materials and Construction:

• Cast from XG-150 high carbon alloyed iron for superior strength and durability
• Thermal Stability Profiling (TSP) heat treatment relieves internal stresses and optimizes rotor stability
• Cross-drilled and slotted surface design expels brake dust, gases, and moisture for consistent pad contact
• Black painted non-friction areas resist corrosion and enhance appearance

Patented Kangaroo Paw Ventilation:

• Features 144 diamond and teardrop-patterned pillars between rotor faces
• Achieves up to 30% increase in surface area compared to traditional straight vane designs
• Delivers up to 20% improvement in cooling efficiency for reduced brake fade
• Extends both pad and rotor service life through superior heat dissipation

Thermo-Graphic Heat Paint (TGHP):

• Color-changing heat indicators monitor rotor temperature in real-time
• Green, orange, and red stripes change color at predetermined critical temperature thresholds
• Helps drivers make informed decisions about driving style and brake pad selection

The XS cross-drilled and slotted configuration is ideal for high-performance street driving where both aggressive stopping power and enhanced aesthetics are desired. The symmetrical drill and slot pattern allows universal left/right rotor use for simplified installation. While not recommended for severe motorsports or heavy off-road use, the 4000 Series XS delivers exceptional performance for spirited street driving and light track day use.
