4000 Series T3 Technology
DBA's 4000 Series T3 rotors are engineered for high-performance applications where thermal capacity and braking consistency are critical.
The T3 slot design builds on DBA's T2 slot technology by adding precisely machined Tri-Symmetrical slots. These additional exit points help friction dust and gases escape from the pad-to-rotor interface, supporting more consistent braking performance and pedal feel during repeated stops.
The Kangaroo Paw ventilation system uses an internal vane design to improve airflow through the rotor and help dissipate heat. Combined with XG-150 high-carbon alloyed iron, heat treatment, and DBA's Thermal Stability Profiling, the 4000 Series is engineered to withstand demanding braking conditions.
Performance Benefits
The DBA42445S is designed for drivers who demand more from their brakes than a standard replacement rotor can provide.
The combination of high-carbon construction, heat treatment, internal ventilation, and T3 slotting helps provide consistent braking performance under repeated high-load conditions. The rotor is suitable for high-performance street use as well as track-day applications.
Installation
The DBA42445S is designed as a direct-replacement rear rotor for compatible Dodge Charger and Challenger SRT Hellcat applications equipped with the 6-piston Brembo caliper.
Follow the vehicle manufacturer's recommended brake installation procedures and complete the appropriate rotor and pad bedding process after installation.
Always verify the vehicle's exact rear brake configuration and 6-piston Brembo caliper fitment before ordering.
