Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC line, which focuses on rotors featuring drilled and slotted surfaces to improve brake pad bite and heat dissipation. This rotor’s vented design helps reduce brake fade during demanding driving conditions, while the rust-resistant coating extends rotor life. The silver zinc finish on the hat area provides additional corrosion protection, making it suitable for daily driving and light towing applications on compatible Chevrolet and GMC vehicles.

Technical Specifications and Features

This rotor measures 295 mm in outside diameter and 73 mm in overall height, fitting vehicles with a 5-lug bolt pattern and a bolt circle diameter of 120.7 mm. The drilled and slotted surface is directional, designed to channel away gases and debris for improved braking efficiency. The nominal thickness of 20 mm ensures durability, with a discard thickness of 18.5 mm indicating when replacement is necessary. The rotor’s center hole diameter is 70.7 mm, and the bolt hole diameter is 13.1 mm, matching factory specifications for a secure fit.

Applications and Problem Solving

• Reduces brake fade during heavy braking or towing
• Improves heat dissipation to maintain consistent braking performance
• Minimizes rust and corrosion with zinc silver coating
• Enhances braking response with drilled and slotted surface
• Restores proper rotor thickness and surface condition for safe stopping

Installation Notes and Tips

Ensure the rotor is installed on compatible Chevrolet Blazer, GMC Jimmy, S10, or Sonoma models with a 5-lug bolt pattern and 120.7 mm bolt circle diameter. Verify the rotor thickness before installation and replace if below the discard thickness of 18.5 mm. Clean the hub surface before mounting to prevent runout. Use proper torque specifications on lug nuts to avoid rotor warping.
