• Directional drilled and slotted surface for improved brake cooling
• Vented rotor design to reduce heat buildup
• Black zinc-coated hat finish for corrosion resistance
• Nominal thickness of 20 mm with discard thickness at 18 mm
• Five bolt holes with 12.9 mm diameter and 114.3 mm bolt circle diameter
• Overall diameter of 316 mm and height of 67.5 mm

Product Line Details: DFC Brake Rotor - Drilled and Slotted - Black

The DFC Brake Rotor - Drilled and Slotted - Black line by Dynamite Friction focuses on rotors that combine drilled holes and slots on the braking surface. This design helps to evacuate gases, dust, and water more efficiently than plain rotors, contributing to improved brake response and reduced fade. The black zinc coating on the rotor hat enhances rust resistance, extending the rotor's service life under various driving conditions.

Technical Specifications and Features

This disc brake rotor is vented, allowing air to flow between the rotor surfaces to dissipate heat effectively during braking. The directional surface pattern, featuring both drilled holes and slots, is optimized for Subaru Impreza models to maintain consistent braking performance under demanding conditions. The rotor measures 316 mm in outside diameter with a height of 67.5 mm, fitting precisely with the vehicle's brake assembly. The zinc black finish on the hat provides additional protection against corrosion, while the plain disc finish ensures a smooth braking surface. The rotor includes five bolt holes with a diameter of 12.9 mm and a bolt circle diameter of 114.3 mm, matching the Subaru Impreza's specifications.

Applications and Problem Solving

• Replaces worn or warped rotors on Subaru Impreza models
• Reduces brake fade caused by excessive heat buildup
• Improves braking performance in wet or dusty conditions
• Minimizes rust and corrosion on rotor hats for longer durability
• Addresses uneven brake pad wear due to rotor surface imperfections

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 18 mm before installation. Properly torque the five lug bolts to the manufacturer’s specifications using the 12.9 mm bolt holes and 114.3 mm bolt circle diameter. The directional drilled and slotted surface must be installed with the rotation direction matching the vehicle’s forward motion for optimal performance. Clean the rotor surface with brake cleaner before mounting to remove any protective coatings or contaminants.

Quality Assurance

Dynamite Friction manufactures the 633-13017L rotor to meet OEM standards for fitment and performance on Subaru Impreza vehicles. The rust-resistant zinc black coating on the rotor hat enhances longevity. While no specific warranty information is provided, Dynamite Friction products are designed to comply with industry quality and safety standards.
