DBA 4000 Series Plain Rotor (REAR)
2017–2020 Toyota 86 / 2013–2020 Subaru BRZ / 2013–2016 Scion FR-S
DBA42663-10
Overview:
The DBA 4000 Series Plain Rotor (REAR) is a high-performance replacement brake rotor designed specifically for the Toyota 86, Subaru BRZ, and Scion FR-S models within the specified year ranges. Crafted for drivers who demand reliable braking performance under both spirited street driving and controlled race conditions, this rotor combines advanced metallurgy with innovative cooling technology to deliver consistent stopping power and durability.
Whether you are upgrading your vehicle’s braking system for enhanced safety, improved pedal feel, or better heat management during aggressive driving, the 4000 Series rotor offers a direct-fit solution that maintains an OE-style appearance while providing superior performance benefits.
Key Features:
This rotor incorporates advanced materials and design elements to optimize braking efficiency and longevity. Key features include:
- Constructed from DBA’s proprietary XG-150 high carbon alloyed iron, engineered to withstand increased stress and heat generated during intense braking.
- Thermal Stability Profiling (TSP) process enhances rotor durability by reducing the risk of warping and cracking under high temperatures.
- Patented Kangaroo Paw ventilation system featuring 144 diamond and teardrop-shaped pillars that increase surface area by up to 30% and improve cooling efficiency by 20% compared to traditional straight vane rotors.
- 4000 Series HD variant offers a smooth, OE-style rotor finish, ideal for drivers seeking the performance benefits of the 4000 Series with a clean, factory appearance.
- Thermo-graphic paint markings (THGP) provide visual indication of rotor temperature for monitoring during demanding use.
- Direct replacement fitment ensures easy installation without modification or special tools.
- Moisture-proof corrosion protection packaging helps prevent rust during storage and shipping.
Construction & Design:
The rotor’s construction centers on the XG-150 high carbon alloyed iron, a material selected for its excellent thermal conductivity and resistance to wear. The Thermal Stability Profiling process further enhances the rotor’s ability to maintain structural integrity under repeated heavy braking cycles, reducing the likelihood of warping or cracking.
DBA’s unique Kangaroo Paw ventilation design improves airflow through the rotor, allowing heat to dissipate more effectively. This ventilation system uses a series of intricately shaped pillars that maximize surface area and cooling without compromising rotor strength. The smooth OE-style finish of the 4000 Series HD variant ensures compatibility with controlled race divisions and drivers who prefer a more understated look.
Installation & Fitment:
The DBA 4000 Series Plain Rotor is a direct replacement for the rear rotors on the 2017–2020 Toyota 86, 2013–2020 Subaru BRZ, and 2013–2016 Scion FR-S. It installs using factory mounting points and requires no cutting, drilling, or special tuning, making it a straightforward upgrade for enthusiasts and daily drivers alike.
