DBA42663S-10

Overview:

The DBA 4000 Series Rear Slotted Rotor is engineered to deliver superior braking performance for Subaru BRZ models from 2013 to 2017 and Subaru WRX models from 2008 to 2013. Designed as a direct replacement for your factory rear rotors, this high-performance rotor combines advanced materials and innovative design to enhance braking efficiency, heat dissipation, and durability. Ideal for enthusiasts seeking improved stopping power and consistent brake feel during spirited driving or daily use.

Whether you are upgrading your braking system for track days, spirited street driving, or simply replacing worn components, the DBA 4000 Series rotor offers a reliable and effective solution that maintains OEM fitment and quality standards.

Key Features:

DBA’s 4000 Series rotors incorporate cutting-edge technology and design elements to optimize braking performance and rotor longevity. Key features include:

• High Carbon Iron Construction: Utilizes premium high carbon, heat-treated iron for enhanced strength and resistance to cracking and warping under extreme conditions.
• Patented Kangaroo Paw Ventilation: Unique vent design improves airflow and heat dissipation, reducing brake fade and maintaining consistent performance.
• Tri-Symmetrical Slotting: Precision-machined slots help remove brake dust and gases, improve pad bite, and maintain clean rotor surface contact.
• Direct OEM Replacement: Designed to match factory rotor dimensions and mounting points for straightforward installation without modifications.
• Enhanced Heat Management: Ventilation and material choices work together to keep rotor temperatures lower during aggressive braking.
• Corrosion Resistant Coating: Protective coating on non-friction surfaces helps prevent rust and extends rotor life.

Construction & Design:

The DBA 4000 Series rotors are crafted from high carbon iron that undergoes a specialized heat treatment process to maximize hardness and durability. This material choice improves thermal conductivity and resistance to cracking, a common issue with standard rotors under high stress. The patented Kangaroo Paw ventilation system features a unique vane design that increases airflow through the rotor, effectively dissipating heat generated during braking.

Additionally, the tri-symmetrical slot pattern is engineered to optimize pad contact and remove debris, ensuring consistent braking performance and reducing the risk of uneven pad wear. The rotors are precision-machined to tight tolerances, guaranteeing a perfect fit and smooth operation with OEM brake pads and calipers.

Installation & Fitment:

Designed as a direct replacement for the rear rotors on Subaru BRZ (2013–2017) and Subaru WRX (2008–2013) models, the DBA 4000 Series rotors install easily using standard tools and procedures. No modifications to the vehicle’s braking system are required, making them an ideal upgrade or replacement part for enthusiasts and daily drivers alike. It is recommended to replace rotors in pairs and to inspect brake pads and hardware during installation to ensure optimal performance and safety.
