DBA DBA42959S Series Slotted Brake Rotor - 4000 T3 290mm

The DBA 4000 Series T3 is the ultimate in direct replacement single-piece performance brake rotors, designed for drivers seeking upgraded braking performance beyond standard OE levels. Featuring all the benefits of the 4000 Series plus DBA's patented world-renowned T3 bi-directional slot design, this rotor delivers exceptional stopping power for high-performance street cars, track vehicles, and demanding applications.

Advanced T3 Slot Technology:

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. Machined slots in the friction surface allow a channel for braking by-products - brake dust and gases from the incredible heat - to escape. This has a multitude of benefits, from reducing pad contamination, controlling heat build-up, and brake pad knock back.

Premium Materials and Construction:

• Cast from XG-150 high carbon alloyed iron and undergoing Thermal Stability Profiling (TSP)
• Features DBA's patented Kangaroo Paw ventilation that implements a series of 144 diamond and teardrop patterned pillars
• Achieves up to a 30% increase in surface area and 20% improvement in cooling efficiency compared to traditional straight vane designs
• CBN (Cubic Boron Nitride) machine turned finish, minimising disc thickness variation
• Paint markings change colour at specific temperature thresholds to assist with monitoring braking temperatures
• Symmetrical slotting for universal left/right use
• Black high-temperature coating for corrosion resistance

Rated for severe motorsports use, these rotors will take a thrashing without missing a beat. The Thermal Stability Profiling process subjects the iron to prolonged heat cycles under controlled conditions, ensuring maximum thermal stability and reduced metal fatigue in extremely demanding applications. This 290mm rotor is sold individually.
