DBA4654S-10

Overview:

The DBA 4000 Series Slotted Rotor is a high-performance front brake rotor designed as a direct replacement for select Subaru WRX STI, Subaru BRZ, and Toyota 86 models. Engineered for enthusiasts seeking enhanced braking performance, these rotors deliver improved heat dissipation and consistent stopping power under demanding driving conditions. Whether you drive daily, enjoy spirited road driving, or participate in occasional track events, these rotors provide reliable, fade-resistant braking to help you maintain control and confidence behind the wheel.

Built with advanced materials and innovative design features, the 4000 Series rotors offer a significant upgrade over factory components without compromising fitment or requiring modifications. They are ideal for drivers who want to improve brake response and durability while maintaining OEM compatibility.

Key Features:

These rotors incorporate DBA’s latest technology to maximize braking efficiency and longevity:

• Constructed from high carbon, heat-treated iron for superior strength and thermal stability.
• Patented Kangaroo Paw ventilation design enhances airflow to reduce heat buildup and minimize brake fade.
• Tri-symmetrical slotting pattern optimizes pad bite and helps evacuate dust and gases for consistent braking performance.
• Precision-machined to ensure perfect fitment and smooth rotor surface for improved pad contact.
• Designed as a direct bolt-on replacement using factory mounting points, maintaining OEM specifications.
• 10 stud hole configuration tailored for performance package-equipped vehicles.
• Durable finish resists corrosion and extends rotor service life.

Construction & Design:

The DBA 4000 Series rotors are engineered with a focus on durability and thermal management. The high carbon iron material undergoes heat treatment to increase hardness and resistance to cracking under extreme conditions. The unique Kangaroo Paw ventilation system features a series of internal ribs that increase surface area and promote rapid heat dissipation, reducing the risk of brake fade during aggressive driving.

The tri-symmetrical slotting pattern is carefully designed to maintain consistent pad contact, improve wet-weather braking, and channel away debris and gases generated during braking. This combination of materials and design ensures the rotors maintain structural integrity and performance over extended use.

Installation & Fitment:

These rotors are engineered for a straightforward installation process, fitting directly onto the front hubs of compatible vehicles without any need for modifications. They utilize the factory mounting points and maintain the original rotor dimensions to ensure proper alignment and brake system function.

No cutting, drilling, or special tuning is required, making these rotors an ideal upgrade for enthusiasts looking to enhance braking performance with minimal effort.

• Direct replacement for front rotors on Subaru WRX STI (2004–2014), Subaru WRX STI (2015–2016), Subaru BRZ (2013–2020), and Toyota 86 (2017–2020) with performance package and 10 stud hole configuration.
