DBA DBA43051XS-10 4000 Series XS Cross-Drilled Slotted Rear Brake Rotor

The DBA 4000 Series XS brake rotor is a direct replacement single-piece performance rotor designed for drivers seeking upgraded braking performance above and beyond standard OE levels. Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP), DBA's metallurgy is able to handle the increased stress and heat generated under intense braking applications.

Key Features:

• Cross-drilled and slotted design for enhanced heat dissipation, reduced brake fade, and improved water evacuation
• Patented Kangaroo Paw ventilation 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
• Thermal Stability Profiling (TSP) proprietary process subjects XG-150 grey iron to prolonged heat cycles under strictly controlled conditions to relieve internal stresses and ensure maximum thermal stability
• Thermo-Graphic Heat Paint (TGHP) markings with Green, Orange and Red stripes that change color at predetermined critical temperature thresholds
• Gold high temperature protective coating on non-friction areas for corrosion resistance and long-lasting appearance

The XS version is not recommended for motorsports usage, but is more than capable for high performance street use. This rear rotor fits Subaru STI models equipped with the yellow Brembo Spec R 6-pot calipers and 19-inch wheels (2017+). Sold individually.
