Product Line Details

The DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC line, which focuses on rotors designed to improve braking efficiency through enhanced surface features. The drilled and slotted design helps reduce brake fade by allowing gases and debris to escape, while the zinc silver coating on the hat provides corrosion resistance, extending rotor life under various driving conditions.

Technical Specifications and Features

This disc brake rotor is vented to improve airflow and cooling during braking, which is critical for maintaining performance in demanding driving situations. The rotor’s nominal thickness is 20 mm, with a discard thickness of 18.4 mm, ensuring clear service limits for safety. The rotor measures 305 mm in outside diameter and 55.6 mm in height, fitting precisely on Chevrolet Corvette models that require a 5-lug bolt pattern with 13 mm bolt hole diameter and a 120.7 mm bolt circle diameter. The directional slotted and drilled surface enhances water and dust dispersion, improving brake pad contact and reducing noise.

Applications and Problem Solving

• Replaces worn or warped rotors on Chevrolet Corvette vehicles
• Improves heat dissipation to reduce brake fade during aggressive driving
• Helps maintain consistent braking performance in wet or dusty conditions
• Prevents rust and corrosion with zinc silver coated hat finish
• Supports safe braking by providing clear discard thickness limits

Installation Notes and Tips

Ensure the rotor is compatible with your Chevrolet Corvette model before installation. Clean the hub surface to remove rust or debris for proper rotor seating. Torque lug nuts to manufacturer specifications and check rotor thickness regularly to maintain safety. The directional surface requires correct orientation during installation to function as intended.
