DBA DBA42052XS Series Drilled Slotted Brake Rotor - 4000

The DBA DBA42052XS is part of DBA's renowned 4000 Series — a premium performance brake rotor featuring a cross-drilled and slotted surface design engineered for drivers who demand superior stopping power and fade resistance. Manufactured by Disc Brakes Australia (DBA), a globally trusted name in performance braking, this rotor delivers a significant upgrade over standard OEM replacements.

Key Features:

• Cross-Drilled & Slotted Design: The combination of drilled holes and machined slots work together to evacuate heat, gas, and debris from the rotor face, improving bite and reducing brake fade under repeated or aggressive braking
• 4000 Series Construction: Features DBA's proprietary Geomet® rust-inhibiting coating on the hat and outer edges to resist corrosion and extend rotor life
• Enhanced Heat Dissipation: The rotor's vented construction and surface treatments allow for faster thermal recovery between braking events, maintaining consistent pedal feel
• Improved Pad Degassing: Slots channel away gases produced by brake pad outgassing, preventing pad glazing and maintaining consistent friction coefficient
• Balanced Performance: Designed for street and performance driving, offering a strong upgrade from OEM without compromising daily drivability
• DBA Quality: Manufactured to stringent Australian and international standards with OEM-level fitment precision

The DBA 4000 Series XS (Extra Slot) rotors are an ideal choice for performance-oriented drivers seeking better braking response, reduced stopping distances, and longer rotor life compared to standard smooth rotors. Direct OEM replacement fitment ensures straightforward installation with no modifications required.
