DBA DBA52844SLVS 5000 Series T3 Slotted 2-Piece Brake Rotor 370mm Silver Hat

The DBA 5000 Series T3 Slotted Brake Rotor represents premium two-piece brake rotor technology designed for high-performance street vehicles, track days, club racing, and rally applications. This direct replacement rotor combines advanced materials engineering with race-proven design features to deliver exceptional stopping power and thermal management.

Key Features:

• Two-piece composite construction with high-carbon XG-150 cast iron friction ring and aerospace-grade T6061-T6 aluminum hat
• T3 bi-directional slot design with 48 CNC-machined curved slots for optimal brake pad degassing and reduced noise
• Kangaroo Paw ventilation system provides 30% more surface area and 20% improved cooling efficiency versus straight vane designs
• Thermal Stability Profiling (TSP) heat treatment aligns grain structure at the atomic level for superior thermal performance
• CBN machine-turned friction surface ensures optimal pad contact and break-in
• Secured with National Aerospace Standards (NAS) specification bolts and crimp nuts
• Thermographic heat paint markings change color at specific temperature thresholds for visual monitoring
• ECE R90 approved for street legal performance applications

Technical Specifications:

• Rotor diameter: 370mm (14.57 inches)
• Rotor thickness: 34mm maximum, 32mm minimum
• Hub hole diameter: 65.04mm
• Bolt circle diameter: 142mm
• Bolt pattern: 5-bolt configuration
• Disc height: 59.70mm
• Finish: Clear anodized silver aluminum hat with slotted cast iron rotor

Performance Benefits:

The aluminum hat construction reduces unsprung weight while preventing heat transfer from the rotor to the hub assembly, protecting wheel bearings and improving vehicle dynamics. The unique T3 curved slot pattern effectively channels brake dust and gases away from the pad contact surface while minimizing the vibration and noise associated with traditional straight-slot designs. Replacement friction rings are available separately, allowing cost-effective rotor service while reusing the aluminum hats.

Ideal for enthusiasts demanding race-level performance with street-legal certification and quiet operation. Price is for single rotor—order quantity of two for complete axle replacement.
