DBA 4000 Series Drilled/Slotted Front Brake Rotor for Subaru WRX STi (2017+)

If you're looking to upgrade your Subaru WRX STi's braking system, the DBA 4000 Series Drilled/Slotted Front Brake Rotor is an excellent choice. Designed specifically for the 2017 and newer models, this rotor offers a remarkable performance boost over standard OE options.

Why Choose the DBA 4000 Series?

These rotors are crafted from high carbon alloyed iron, making them incredibly durable. Thanks to DBA's Thermal Stability Profiling, they can withstand the intense heat and stress that comes with aggressive driving or track days. You can trust that these rotors will hold up under pressure, providing you with reliable stopping power every time.

Innovative Design Features

The DBA 4000 Series features a unique Kangaroo Paw ventilation system. This design incorporates 144 diamond and teardrop-shaped pillars, which significantly increase the surface area and improve cooling efficiency by up to 20% compared to traditional straight vane designs. This means better heat dissipation and less fade during those high-stress moments.

Product Features

• Surface Design: Symmetrical slots and chamfered drill holes help in expelling friction dust and gases, leading to a quieter and more responsive braking experience.
• Anti-Rust Coating: The non-friction areas are painted to prevent rust, enhancing both appearance and longevity.
• Bi-Directional Use: These rotors are designed for universal left and right use, making installation straightforward.
• Thermal Stability Profiling: Specialized heat treatment cycles realign the rotor's microstructure, boosting stability and durability.
• Thermal Efficiency: Centre-split core castings allow for improved heat transfer, ensuring your brakes stay cool even under heavy use.
• Thermographic Heat Paint: The paint markings change color at certain temperature thresholds, providing a visual cue to monitor braking temperatures and rotor fatigue.
• CBN Finish: The CBN (Cubic Boron Nitride) machine-turned finish minimizes disc thickness variation, reducing the risk of premature pad wear.
• High Carbon Alloyed Iron: This formulation works perfectly with DBA's thermal stability profiling, allowing the rotor to handle extreme heat over prolonged periods.
• Kangaroo Paw Design: The unique vane design offers up to 20% better heat dissipation, which enhances braking effectiveness and extends brake life.

Perfect Fit for Your Subaru

• Compatible with Subaru WRX STi models from 2017 and onwards.

Upgrade your braking system with the DBA 4000 Series Drilled/Slotted Front Brake Rotor and experience the difference in performance and reliability. Your Subaru WRX STi deserves the best, and this rotor is designed to deliver just that!
