Dynamite Friction 631-68012L Disc Brake Rotor - Front Left

Drilled and Slotted Front Left Rotor

The Dynamite Friction DFC Brake Rotor - Drilled and Slotted - Silver, part number 631-68012L, is a vented front left disc brake rotor built for performance-focused braking systems. Its 355 mm outside diameter, 32 mm nominal thickness, and directional slotted-and-drilled surface support consistent brake response for select Nissan and INFINITI applications.

With a zinc silver hat finish and rust-resistant coating, this rotor is made to maintain a cleaner appearance while helping resist corrosion on exposed surfaces. The plain disc finish, 5-lug pattern, and 114.3 mm bolt circle match the listed fitments for vehicles such as the Nissan 370Z, Nissan Z, INFINITI Q50, and INFINITI Q60.

Product Details

The DFC Brake Rotor - Drilled and Slotted - Silver line focuses on application-specific rotors with a directional braking surface and corrosion-resistant finish. This rotor is listed for front left use on performance-oriented platforms including the 2023-2025 Nissan Z with Akebono 4 piston front and dual piston rear calipers, 2021-2024 INFINITI Q50 with 4 piston front calipers, and 2009-2020 Nissan 370Z with Sport Performance Brakes. The same part number 631-68012L also appears across multiple INFINITI sport-package applications, including Q60, Q70, Q70L, FX50, G37, M35h, M37, M56, and QX70 listings.

This rotor is intended for vehicles using the specified front left brake configuration and matching rotor dimensions. It is a direct-fit style replacement for the listed applications and should be matched carefully to caliper package, brake package, and model year details before installation.

What This Rotor Helps Address

• Brake fade from repeated high-temperature stops
• Uneven rotor surface wear on performance brake systems
• Corrosion on exposed rotor hat areas
• Brake vibration caused by worn or out-of-spec rotors
• Reduced braking consistency on sport-package vehicles

Installation Notes and Tips

Verify rotor diameter, thickness, bolt pattern, center bore, and front left position before installation. This rotor is directional, so orientation matters during mounting. Confirm caliper type and brake package on Nissan 370Z, Nissan Z, INFINITI Q50, and INFINITI Q60 applications, especially where sport or performance brake packages are specified. Inspect pads, calipers, and hub surfaces for wear or contamination before installing the new rotor.

Quality Assurance

Dynamite Friction manufactures this rotor with a rust-resistant coating and zinc silver hat finish to support long-term appearance and service life in brake applications. Part number 631-68012L is built to the listed dimensional specifications for the confirmed fitments.
