Product Description

The DBA 4908S is a 4000 Series T3 slotted rear brake rotor engineered for the Nissan Skyline R32, R33 GTS25t, R34 GT/GT-T, and 300ZX Z32 platforms. Cast from DBA's proprietary XG150 high-carbon alloyed iron and heat treated through Thermal Stability Profiling, this rotor handles extreme braking temperatures without fade or distortion. The patented Kangaroo Paw internal ventilation system uses 144 diamond and teardrop-shaped pillars to increase cooling vane surface area by up to 30% and improve airflow efficiency by up to 20% over conventional straight vane designs. DBA's CNC-machined tri-symmetrical T3 slot pattern provides multiple exit points for brake dust and gases, delivering quieter operation, smoother pedal feel, and consistent pad contact under all driving conditions. Thermal Graphic Heat Paint on the rotor face changes color at specific temperature thresholds to help monitor braking temperatures. A direct bolt-on replacement for the factory rear rotor with no modifications required. Sold individually.
