DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on rotors that combine drilled holes and slots to optimize brake pad cleaning and heat dissipation. This design helps maintain consistent braking performance under demanding conditions. The directional surface pattern further aids in channeling gases and debris away from the rotor surface, which is particularly beneficial for Subaru models like the Crosstrek and Forester that may encounter varied driving environments.

Detailed Product Description

This disc brake rotor is a solid type with a nominal thickness of 10 mm and a discard thickness of 8.5 mm, ensuring a reliable service life before replacement is necessary. The rotor’s 274 mm outside diameter and 63.6 mm height are designed to match the specific brake system requirements of Subaru Crosstrek, Forester, Impreza, and XV Crosstrek vehicles. The rotor features a plain disc finish combined with a Geospec silver grey hat finish that provides rust resistance, extending the rotor’s durability. The 5-bolt hole configuration with a 13 mm diameter and 100 mm bolt circle diameter ensures proper fitment and secure mounting. The directional slotted and drilled surface improves braking efficiency by enhancing pad bite and heat dissipation, reducing brake fade during extended use.

Common Applications and Problem Solving

• Replacement rotor for worn or warped Subaru Crosstrek and Forester brake systems
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps maintain consistent braking performance in wet or muddy conditions
• Addresses rotor surface glazing and pad material buildup with slotted and drilled design
• Prevents rust and corrosion on rotor hats for longer service life

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (8.5 mm) before installation
• Clean mounting surface and hub to prevent rotor runout
• Torque lug nuts to manufacturer specifications for Subaru models
• Check compatibility with existing brake pads and calipers
• Perform a bed-in procedure after installation for optimal braking performance
