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

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction is designed to provide enhanced braking efficiency through its drilled and slotted surface. This design helps to reduce brake fade by improving heat dissipation and allowing gases and debris to escape during braking. The zinc silver coating on the rotor hat offers corrosion resistance, extending the rotor's service life, especially in environments prone to rust.

Technical Specifications and Features

This disc brake rotor is engineered with a nominal thickness of 12 mm and a discard thickness of 10.4 mm, ensuring safe replacement intervals. The rotor’s 328 mm outside diameter and 76.5 mm height are optimized for Jeep Wrangler brake systems. The rotor includes five bolt holes with a 17 mm diameter and a 127 mm bolt circle diameter, matching the Wrangler’s hub specifications. The directional slotted and drilled surface improves braking performance by maintaining cleaner pad contact and reducing heat buildup.

Applications and Problem Solving

• Improves braking performance for Jeep Wrangler vehicles
• Reduces brake fade during heavy or repeated braking
• Helps prevent rotor warping caused by excessive heat
• Minimizes rust and corrosion on the rotor hat
• Maintains consistent brake pad contact for smoother stops

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation. Verify bolt hole alignment with the hub using the 127 mm bolt circle diameter and 17 mm bolt hole diameter. Check rotor thickness before installation to confirm it exceeds the discard thickness of 10.4 mm. Proper torque specifications should be followed to avoid rotor damage or uneven wear.
