OVERVIEW

DBA's 5000 Series Drilled rotor delivers aggressive cooling performance through precision-drilled venting, ideal for high-demand street and track applications. The drilled pattern increases surface area for heat dissipation while maintaining the lightweight 2-piece composite construction that defines the 5000 Series platform. Engineered for drivers who demand maximum braking responsiveness with the confidence of advanced thermal management on weekend track days and spirited street driving.

FEATURES

• Precision-Drilled Venting Pattern: Machined through-holes increase cooling surface area and heat dissipation rates, ideal for high-demand braking scenarios and sustained track sessions.
• Lightweight 2-Piece Composite Construction: Aerospace-grade billet aluminum (T6061-T6) center hat bonded to high-carbon cast-iron rotor ring via NAS bolts and crimp nuts.
• Thermal Stability Profiling (TSP): Optimized heat management for sustained track temperatures and heavy braking cycles without fade or distortion.
• Reduced Unsprung Weight: Aluminum hats minimize unsprung mass, improving suspension response and reducing heat transfer to chassis and suspension components.
• Heat Paint Markings: Temperature-sensitive paint changes color at specific thresholds to monitor peak braking temperatures and rotor service life.
• Aerospace-Grade Fastening: NAS bolts and crimp nuts ensure durability and reliability under extreme thermal and mechanical cycling.
• Premium Street & Track Performance: Suitable for weekend track days, club racing, and spirited street driving with consistent, fade-free stopping power.
• Proven Performance Heritage: DBA rotors are trusted by performance drivers, motorsport competitors, and enthusiasts worldwide.
