DBA DBA4086XS Series XS Cross-Drilled Slotted Disc Brake Rotor - 4000

The DBA DBA4086XS is part of DBA's (Disc Brakes Australia) 4000 Series XS line — a premium performance brake rotor featuring a unique combination of cross-drilling and Geomet^®-coated slotting technology designed for improved thermal performance and consistent stopping power under demanding conditions.

DBA's proprietary Unified Slot™ (XS) pattern works in conjunction with cross-drilled holes to continuously sweep debris, gases, and brake dust away from the rotor face, maintaining maximum pad-to-rotor contact at all times. The result is shorter stopping distances, reduced brake fade, and extended pad life compared to standard OE rotors.

Key Features:

• Cross-Drilled & Unified Slot™ (XS) Design — dual-action surface for superior heat dissipation and pad degassing
• Geomet® Corrosion-Resistant Coating — protects non-friction surfaces from rust and corrosion without affecting braking performance
• Improved Heat Handling — vented rotor construction evacuates heat rapidly to reduce brake fade during repeated or heavy stops
• Balanced Thermal Expansion — precision-machined to minimize vibration, pedal pulsation, and rotor warping
• Direct OEM Replacement — bolt-on fitment with no modifications required
• Street & Track Capable — engineered to perform in both everyday driving and high-performance applications
• Manufactured to ISO/TS 16949 quality standards

DBA is an Australian-owned manufacturer with decades of experience supplying brake components to OEM, motorsport, and aftermarket customers worldwide. The 4000 XS Series represents an ideal upgrade for drivers seeking enhanced braking performance and durability over standard replacement rotors.
