DBA DBA42965S 4000 Series T3 Slotted Rear Brake Rotor 280mm

The DBA 4000 Series T3 slotted brake rotor is a high-performance, single-piece rear disc designed for drivers seeking superior braking performance beyond OE standards. Engineered specifically for 2015+ Mazda MX-5 Miata 2.0L applications, this 280mm rotor delivers enhanced stopping power with reduced noise and improved pedal feel.

Advanced T3 Slot Technology:

• Precision CNC-machined tri-symmetrical slot design provides quieter operation than traditional slotted rotors
• Bi-directional slot pattern eliminates the need for left and right specific rotors
• Increased exit points for brake dust and gases improve consistency and effectiveness with every stop
• Enhanced pad bite and more responsive pedal feedback compared to OE rotors

Superior Metallurgy and Heat Management:

• Cast from XG-150 high carbon alloyed iron for exceptional durability
• Thermal Stability Profiling (TSP) heat treatment process enhances resistance to warping and cracking
• Kangaroo Paw ventilation system features 144 diamond and teardrop-patterned pillars for up to 30% increase in surface area and 20% improvement in cooling efficiency
• Thermographic heat paint markings change color at specific temperature thresholds to monitor braking temperatures and rotor fatigue

Specifications:

• Rotor Diameter: 280mm (11.02")
• Rotor Thickness: 9.5mm
• Minimum Thickness: 7.5mm
• Center Bore: 55mm
• Bolt Pattern: 4-stud
• Position: Rear
• Sold as a pair (both rear rotors included)

Ideal for high-performance street driving, track days, and spirited driving applications where enhanced braking performance and thermal management are critical. The 4000 Series T3 rotors are engineered to provide approximately three times the service life of standard rotors while maintaining consistent performance under extreme heat conditions.
