Details on the DFC Brake Rotor - Drilled and Slotted - Silver Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled holes and slots to improve brake pad bite and reduce heat buildup. This product line is designed to provide consistent braking performance under demanding conditions by facilitating better gas and dust evacuation. The silver zinc coating on the rotor hat offers corrosion resistance, extending the rotor's service life on vehicles such as the Toyota Land Cruiser and FJ Cruiser.

Product Description and Specifications

This disc brake rotor features a vented design that promotes airflow to dissipate heat effectively during braking. The drilled and slotted surface helps maintain clean contact between the brake pad and rotor, reducing the risk of brake fade. With a nominal thickness of 18 mm and a discard thickness of 16 mm, the rotor ensures durability and safety throughout its service life. The zinc silver hat finish provides rust resistance, which is critical for vehicles exposed to varying weather conditions. The rotor is directional, meaning it must be installed in the correct orientation to optimize performance. It includes six bolt holes with a bolt circle diameter of 139.7 mm, compatible with specific Lexus and Toyota models.

Compatible Vehicles and Common Applications

• Replacement rotor for Lexus GX460 and Toyota 4Runner
• Suitable for Toyota FJ Cruiser and Land Cruiser brake system upgrades
• Addresses issues such as brake fade during heavy use
• Helps reduce rotor warping caused by excessive heat
• Improves braking response and pad life by maintaining cleaner rotor surfaces

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated on the rotor. Verify bolt hole alignment with the vehicle’s hub using the 6-bolt pattern and 139.7 mm bolt circle diameter. Check rotor thickness before installation to confirm it meets the minimum discard thickness of 16 mm. Proper torque specifications should be followed to avoid rotor damage or uneven wear.
