Key Features:

DBA’s 4000 Series XS rotors incorporate cutting-edge design elements and premium materials to maximize braking performance and longevity. Key features include:

• High Carbon Iron Construction: Utilizes high carbon content iron for enhanced thermal conductivity and resistance to cracking.
• Patented Kangaroo Paw Ventilation: Unique vane design improves airflow to dissipate heat quickly and evenly.
• Cross Drilled and Slotted Surface: Optimizes pad bite, helps remove brake dust and gases, and reduces glazing for consistent braking feel.
• Precision Balanced: Minimizes vibration and noise for smooth operation.
• Direct Bolt-On Fitment: Designed to match OEM specifications for easy installation without modifications.
• Corrosion Resistant Coating: Protects rotor surfaces from rust and extends service life.
• Enhanced Heat Dissipation: Reduces brake fade during aggressive driving or track sessions.

Construction & Design:

The DBA 4000 Series rotor is crafted from premium high carbon iron that undergoes a specialized heat treatment process to increase hardness and durability. This material choice enhances thermal stability, reducing the risk of warping under high temperatures. The patented Kangaroo Paw ventilation system features uniquely shaped internal vanes that maximize airflow through the rotor, effectively cooling the braking surface.

The cross drilled holes and precision-machined slots are strategically placed to improve pad contact and evacuate gases and debris, maintaining consistent friction and braking performance. The rotor’s surface is coated with a corrosion-resistant finish to prevent rust buildup, ensuring a clean appearance and reliable operation over time.

Installation & Fitment:

This rotor is designed as a direct replacement for the rear brakes on Subaru BRZ models from 2013 through 2017 and Subaru WRX models from 2008 through 2013. Installation requires no modifications and fits using existing hardware and brake components. It is recommended to replace rotors in pairs and to inspect brake pads and other related components during installation to ensure optimal braking system performance.

What's Included:

• One (1) Rear DBA 4000 Series Cross Drilled Slotted Rotor

Ideal For:
