DBA 4926S 4000 Series T3 Front Slotted Brake Rotor for 1989–1995 Nissan Skyline R32 GT-R

Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling. DBA's metallurgy is able to handle the increased stress and heat generated under intense braking application time and time again. Featuring DBA;s patented Kangaroo Paw ventilation that implements a series of 144 diamond and teardrop patterned pillars. DBA achieves up to a 30% increase in surface are and 20% improvement in cooling efficiency compared to traditional straight vane design. DBA's 4000 Series T3 rotors feature our best technology and materials for maximum performance. High carbon & heat treated iron, patented Kangaroo Paw ventilation and Tri-symmetrical slotting makes for the perfect direct replacement rotor Built on the foundations of DBA's T2 slot, the T3 slot design features additional, precise, CNC machined tri-symmetrical slots, resulting in an even quieter, more responsive and smoother brake pedal feel The T3 slot increases the number of exit points for brake pad friction dust and gases to escape through, further increasing the consistency and effectiveness of every brake stop, DBA's revolutionary universal slot design eliminates the need for separate left and right slot designs seen in traditional rotor designs, DBA's 4000 Series T3 rotors are recommended for all performance applications from street driving, 4?4 and SUV, light utility vehicles, track days, rally cars and armored vehicles, DBA's 4000 Series rotors feature: XG-150 High Carbon Alloyed Iron, TSP (Thermal Stability Profiling), Thermo-graphic paint markings (THGP), Direct replacement suitability, Moisture proof corrosion protection packaging

The DBA 4926S 4000 Series T3 front slotted brake rotor is a direct-replacement performance upgrade for the 1989–1995 Nissan Skyline R32 GT-R equipped with the 2.6L twin-turbo engine. Cast from DBA XG-150 high-carbon alloyed iron and treated with Thermal Stability Profiling (TSP), this rotor is engineered to manage the elevated heat and stress generated during demanding street, track, rally, and performance driving applications.

DBA’s patented Kangaroo Paw ventilation system uses 144 diamond- and teardrop-shaped pillars to improve airflow through the rotor. Compared with traditional straight-vane designs, the Kangaroo Paw structure provides up to a 30% increase in surface area and up to a 20% improvement in cooling efficiency. The rotor also features DBA’s Tri-Symmetrical T3 slot design, which helps evacuate brake dust and gases while promoting smoother pedal response, quieter operation, and consistent braking performance.

The DBA 4926S combines high-carbon metallurgy, heat treatment, thermal monitoring markings, corrosion-protection packaging, and direct-fit suitability in a rotor designed for serious performance use. Its universal slot pattern eliminates the need for separate left- and right-hand rotor designs, simplifying installation while maintaining effective friction-surface cleaning. This rotor is recommended for high-performance street vehicles, 4x4 and SUV applications, light utility vehicles, track-day cars, rally vehicles, and other demanding braking environments. Professional installation and inspection of related braking components are recommended before use.
