Detailed Product Description

The DFC Brake Rotor - Drilled and Slotted - Silver is part of Dynamite Friction's DFC line, which focuses on delivering rotors with enhanced cooling and consistent braking performance. The drilled holes and slots on the rotor surface help evacuate gases, dust, and water, improving brake pad contact and reducing the risk of brake fade during heavy use. The solid rotor design provides structural integrity and durability, while the zinc silver hat finish with rust-resistant coating protects against corrosion, extending rotor life.

With a nominal thickness of 7.7 mm and a discard thickness of 7.3 mm, this rotor maintains optimal performance throughout its service life. The 4-bolt hole pattern with an 81 mm bolt circle diameter and 63.6 mm center hole diameter ensures compatibility with specific vehicle applications requiring these dimensions.

Applications and Problem Solving

• Improves braking performance for vehicles experiencing brake fade under heavy loads
• Reduces heat buildup during aggressive driving or towing
• Minimizes brake dust accumulation and water interference for consistent stopping power
• Prevents rust and corrosion on rotor hats for longer service intervals
• Compatible with vehicles requiring a 4-bolt, 81 mm bolt circle diameter rotor

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (7.3 mm) before installation
• Clean rotor surface and hub mounting area to prevent uneven wear or vibration
• Use proper torque specifications for 4-bolt mounting to avoid warping
• Check compatibility with vehicle make and model based on bolt pattern and rotor dimensions
