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 enhanced braking consistency and durability, particularly for vehicles like the Pontiac Fiero that demand precise stopping power. The silver zinc coating on the rotor hat offers corrosion resistance, extending the rotor's service life.

Technical Specifications and Features

This rotor is a solid type with a nominal thickness of 11.05 mm and a discard thickness of 9.5 mm, ensuring it meets safety standards for replacement. The rotor’s outside diameter measures 246 mm, with an overall height of 86.5 mm. It features a 5-lug bolt pattern with 12x1.5 mm bolt hole diameter and a 100 mm bolt circle diameter, matching the Pontiac Fiero’s factory specifications. The directional slotted and drilled surface improves water and gas evacuation, reducing brake fade during aggressive or repeated braking.

Applications and Problem Solving

• Reduces brake fade caused by heat buildup during spirited driving or towing
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust accumulation on the rotor surface
• Restores braking performance on Pontiac Fiero models with worn or warped rotors
• Helps maintain consistent pedal feel and stopping power

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify that the rotor thickness is above the discard thickness of 9.5 mm before mounting. Use proper torque specifications for the 5 lug bolts with 12x1.5 mm thread size. It is recommended to replace brake pads when installing new rotors to ensure optimal performance and longevity.

Quality Assurance

Dynamite Friction manufactures this rotor to meet or exceed OEM specifications for the Pontiac Fiero. The zinc silver hat finish and rust-resistant coating help protect against corrosion, contributing to the rotor’s durability. While no specific warranty information is provided, the product is designed for reliable, long-term use in compatible vehicles.
