DBA 4000 Series T3 Rear Slotted Brake Rotor for 2015-2017 Chevrolet SS (DBA42074S)

Fits 2015-2017 Chevrolet SS Base.

The DBA 4000 Series T3 is a high-performance, direct-replacement rear brake rotor engineered for superior thermal management and consistent stopping power. Built with XG-150 high-carbon alloyed iron, these rotors are designed to withstand the extreme heat cycles encountered in spirited driving and track applications. The patented T3 tri-symmetrical slot design features precise CNC-machined exit points that allow brake pad friction dust and gases to escape efficiently, resulting in a quieter, smoother, and more responsive pedal feel.

To ensure long-term durability, each rotor undergoes Thermal Stability Profiling (TSP) to reduce internal stresses. DBA also integrates Thermo-graphic paint markings (THGP) directly on the rotor edge, providing a visual reference for peak operating temperatures. The universal slot design eliminates the need for side-specific (left/right) rotors, making installation straightforward.

• T3 Slot Design: Tri-symmetrical CNC-machined slots improve consistency and pad bite.
• XG-150 High Carbon Alloy: Enhanced material density for better heat dissipation and resistance to cracking.
• Thermal Stability Profiling (TSP): Optimizes the rotor's microstructure for improved thermal fatigue resistance.
• Thermo-Graphic Paint (THGP): Heat-sensitive markings change color to monitor braking temperatures.
• Direct Replacement: Bolts directly to factory locations with no modifications required.
• Manufacturer Part Number: DBA42074S
