DBA DBA53929.1XD Series Cross-Drilled Dimpled Brake Rotor with NAS Nuts - 5000

The DBA DBA53929.1XD is a 5000 Series Cross-Drilled and Dimpled (XD) performance brake rotor engineered for high-demand driving applications. Designed as a direct-fit replacement for the rear axle of the Chevrolet Corvette C8 Z51, this rotor combines DBA's proven two-piece KP (Knob Pin) hat construction with an aggressive XD surface pattern for maximum thermal performance and consistent pedal feel.

DBA's proprietary Thermal Stability Slots (TSS) and cross-drilled holes work in unison to evacuate heat, gases, and debris from the rotor surface, keeping brake pad contact clean and consistent under repeated hard braking. The dimpled pattern reduces stress concentrations common with fully drilled rotors, extending rotor service life without sacrificing cooling efficiency.

Key Features:

• 5000 Series XD (Cross-Drilled & Dimpled) surface pattern for superior cooling and debris evacuation
• KP (Knob Pin) two-piece hat design for reduced unsprung weight and improved heat dissipation
• NAS Grade Nuts included for secure, precise hat-to-rotor ring assembly
• Precision machined to strict DBA tolerances for minimal runout and vibration-free braking
• Corrosion-resistant coating on non-friction surfaces for extended shelf and service life
• Direct OEM-style fitment — no modifications required for installation
• Designed and engineered in Australia to meet the performance demands of high-horsepower sports vehicles

Whether used on the track or spirited street driving, the DBA DBA53929.1XD delivers the stopping power and thermal management required by the high-performance Corvette C8 Z51 platform. NAS nuts are included to ensure a complete, ready-to-install assembly.
