Dynamite Friction 7004-31109 Disc Brake Rotor Set - Front and Rear

Drilled and Slotted Brake Rotors for GR Supra

Dynamite Friction DFC Rotors-Drilled and Slotted-Silver, part number 7004-31109, are a front and rear disc brake rotor set for select Toyota GR Supra applications. This rotor set is built for drivers who want OE-style fitment with added braking bite, heat management, and cleaner pad contact.

Compatible with 2020-2026 Toyota GR Supra brake rotor replacement needs, including full cast replacement for aluminum hat disc applications and optional design full cast rotors with 330mm rear disc setups.

Key Features

• Drilled holes help reduce heat buildup during repeated braking
• Slotted surface helps clear brake dust and road debris
• Designed to improve pad bite and reduce pad glazing
• GEOSPEC coated rotor construction for corrosion resistance
• G3000/G11H18 cast iron specification for durability and stability
• Non-directional finish supports faster, more even pad bed-in
• 100% inspected for balance and critical dimensions

Product Line Details

The DFC Rotors-Drilled and Slotted-Silver line focuses on performance-oriented brake rotor replacement with OE-matching engineering. For Toyota GR Supra owners, this line combines drilled and slotted rotor design with precision machining to support consistent braking response in street and spirited driving conditions.

Detailed Description

Part number 7004-31109 is engineered for the Toyota GR Supra and is listed for 2020-2026 models at the front and rear position. The rotor casting is machined to tight tolerances, then finished with a non-directional surface to promote even pad transfer and quieter, smoother stops. Each vented rotor is electronically mill-balanced when needed and then checked against critical OE specifications before release.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Brake fade from heat buildup
• Uneven pad wear and glazing
• Brake dust and debris trapped on the rotor face
• Longer stopping distances in wet weather
• Rotor vibration caused by balance or machining variation

Installation Notes and Tips

Verify rotor diameter and rear disc configuration before installation on 2020-2022 Toyota GR Supra models, since fitment notes specify optional design full cast rotors with a 330mm rear disc. Clean the hub mounting surface thoroughly and follow proper brake bedding procedures after installation. Confirm left/right and axle placement against the vehicle service information before assembly.

Quality Assurance

DFC states that each rotor is inspected for balance and critical attributes to meet OE specifications. This rotor set includes a 12 month or 12,000 mile limited warranty against defects in material and workmanship.
