DBA DBA52448.1XS 5000 Series XS Drilled and Slotted Brake Rotor

The DBA DBA52448.1XS is a premium 5000 Series XS drilled and slotted brake rotor designed for high-performance street vehicles, track day use, club racing, and rally applications. This two-piece composite rotor combines advanced materials with proven performance technology to deliver superior braking power and heat management.

Construction and Materials:

• High carbon cast iron rotor ring constructed from XG-150 grey iron
• Aerospace grade aluminum hat (T6061-T6) for reduced unsprung weight
• National Aerospace Standards (NAS) bolts and crimp nuts for secure assembly
• Drilled and slotted design for improved heat dissipation and wet weather performance

Advanced Technology Features:

• Thermal Stability Profiling (TSP) heat treatment process reduces internal stresses and metal fatigue
• Thermo-Graphic Heat Paint (TGHP) markings with color-changing temperature indicators (Green, Orange, Red) to monitor rotor temperatures
• Lightweight two-piece design reduces unsprung weight for improved acceleration and deceleration
• Aluminum hat allows uniform radial disc expansion and reduces heat transfer from disc to hub

Performance Benefits:

• Superior heat dissipation prevents brake fade during demanding driving conditions
• Cross-drilled and slotted pattern provides excellent bite and responsive pedal feel
• Reduced weight improves overall vehicle dynamics and handling
• Enhanced thermal stability for consistent performance under extreme conditions

The DBA 5000 Series XS rotors offer direct bolt-on installation with no modifications required. These rotors are engineered for enthusiasts who demand the highest quality drilled and slotted performance rotors for spirited street driving and occasional track use.
