Product Details

The DFC Brake Rotor - Drilled and Slotted - Silver line focuses on rotor construction and finish details that matter during brake service. This rotor uses a slotted X drilled friction surface to help maintain pad contact consistency, while the vented design supports heat management in front brake applications. The silver zinc hat finish adds corrosion resistance and a cleaner look behind the wheel.

Fits 2022-2026 Toyota GR86, front left. Fits 2022-2025 Subaru BRZ, front left. Fits 2017-2020 Toyota 86, front left. Fits 2012-2014 Subaru WRX, front left. Part number 631-13034L also covers select Subaru Forester, Crosstrek, XV Crosstrek, Impreza, Legacy, Outback, Baja, and Scion FR-S front left applications listed in the fitment data.

Common Brake Service Issues

• Rotor wear that reaches discard thickness
• Brake pulsation from uneven rotor surfaces
• Corrosion on exposed rotor and hat areas
• Reduced braking consistency from heat buildup
• Fitment mismatch on front left brake rotor replacement

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and front left position before installation. Confirm whether your Subaru BRZ application is equipped with the Brembo Performance Brake System, since certain fitments exclude it. Check vehicle production date notes for 2010 Forester applications and confirm the correct rotor side before service. Always inspect pads, caliper condition, and hub surfaces during brake replacement.

Quality Assurance

Dynamite Friction identifies this rotor by precise dimensional specifications, finish details, and application-specific fitment data to support accurate brake service selection. Part number 631-13034L is cataloged for direct vehicle matching across the listed Subaru, Toyota, and Scion front left applications.
