Stoptech Power Slot Rotors
2017–2020 Subaru BRZ / 2019–2020 Toyota 86
126.47019CSL
Overview:
The Stoptech Power Slot 04 Rotor (Front Left) is a high-performance brake rotor engineered specifically for the Subaru BRZ (2017–2020) and Toyota 86 (2019–2020). Designed to deliver superior braking performance and enhanced durability, this rotor is ideal for enthusiasts seeking improved stopping power and reliability on both street and track. Featuring advanced slotting and an optional cryogenic treatment, it provides consistent friction, better heat dissipation, and extended service life compared to standard OEM rotors.
Whether you are upgrading your braking system for spirited driving or replacing worn components with a direct OE fitment, the Power Slot 04 rotor offers a perfect balance of performance, longevity, and corrosion resistance.
Key Features:
Stoptech Power Slot 04 Rotors incorporate cutting-edge technology and design elements to optimize braking efficiency and rotor lifespan:
- Directional Curved Vane Design: Enhances airflow for superior heat dissipation and reduces thermal stress.
- Power Slot 04 Pattern: Precisely engineered slots evacuate gases, dust, and heat to maintain consistent pad contact and reduce brake fade.
- Black E-Coat Anti-Corrosion Coating: Provides superior protection against rust and corrosion, outperforming typical spray paint finishes.
- Double Disc Ground Friction Surface: Ensures a smooth, uniform braking surface for optimal pad bite and extended rotor life.
- Symmetric Vane and Split-Core Casting: Promotes uniform heat distribution and structural integrity.
- Cryogenic Treatment (Optional): A one-time deep freezing process that reduces residual stress and enhances wear resistance for longer service intervals.
- Mill-Corrected Balance: Rotors are inspected and corrected to a tolerance of less than 2 ounces for vibration-free operation.
- Direct OE Replacement: Designed to fit perfectly without modifications, maintaining factory specifications and performance.
Construction & Design:
Manufactured from premium-grade cast iron, the Stoptech Power Slot 04 Rotor features a split-core casting that improves heat dissipation and structural strength. The rotor’s symmetric vane design ensures balanced airflow through the rotor, minimizing hotspots and reducing the risk of cracking under thermal stress. The friction surfaces undergo a double disc grinding process, which not only enhances surface finish but also improves rotor balance and brake pad contact consistency.
Additionally, the black E-Coat finish offers robust corrosion resistance, protecting the rotor from environmental elements and extending its aesthetic and functional lifespan. For customers opting for the cryogenic treatment, the rotor undergoes a deep freeze process that permanently alters the metal’s microstructure, reducing residual stresses and improving wear characteristics.
Installation & Fitment:
The Stoptech Power Slot 04 Rotor is a direct front left replacement for the Subaru BRZ model years 2017 through 2020 and the Toyota 86 from 2019 to 2020. Installation requires no modifications and fits seamlessly with the factory brake calipers and hardware. This ensures a straightforward upgrade or replacement process that maintains OEM safety and performance standards.
For best results, it is recommended to replace rotors in pairs and to inspect brake pads and hardware during installation to ensure optimal braking performance and longevity.
What's Included:
- One Stoptech Power Slot 04 Front Left Rotor
- Black E-Coat corrosion-resistant finish
- Optional cryogenic treatment available upon request (additional fee)
Ideal For:
This rotor is ideal for Subaru BRZ and Toyota 86 owners who demand enhanced braking performance for daily driving, spirited street use, or occasional track days. It suits enthusiasts looking to improve initial brake bite, wet weather response, and overall rotor durability without sacrificing OEM fitment or requiring extensive modifications.
