Detailed Product Description

The DFC Geoperformance Rotor - Drilled and Slotted from Dynamite Friction is designed to meet the braking demands of Subaru vehicles such as the B9 Tribeca, Legacy, Outback, Tribeca, and WRX. This rotor features a vented design that improves heat dissipation during braking, reducing the risk of brake fade under heavy use. The rotor’s surface is both drilled and slotted, which helps to evacuate gases, dust, and water, maintaining consistent brake pad contact and improving overall braking efficiency.

With a nominal thickness of 30 mm and a discard thickness of 28 mm, this rotor ensures a long service life while maintaining safety standards. The rotor’s 316 mm outside diameter and 56.8 mm overall height are engineered to fit precisely on compatible Subaru models. The hat finish in Geospec silver grey adds corrosion resistance and a clean appearance, complemented by a rust-resistant coating that protects the rotor from environmental damage.

DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line focuses on delivering rotors with enhanced surface designs that improve braking performance and rotor longevity. The drilled and slotted surface type is directional, which means it is optimized for specific rotational direction to maximize heat dissipation and debris removal. This product line is suitable for drivers seeking reliable braking components that maintain performance under demanding conditions.

Common Applications and Problem Solving

• Reduces brake fade during aggressive or prolonged braking
• Improves braking performance in wet or dusty conditions
• Minimizes rotor surface glazing and pad deposits
• Prevents rust and corrosion for longer rotor life
• Ensures proper fitment and compatibility with Subaru B9 Tribeca, Legacy, Outback, Tribeca, and WRX

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation. Verify bolt hole alignment with the 5-lug pattern and 114.3 mm bolt circle diameter. Check rotor thickness before installation; replace if below the discard thickness of 28 mm. Clean the rotor surface to remove any protective coatings or residues before mounting brake pads.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The rust-resistant coating and precision machining contribute to consistent braking performance and durability. Warranty information is available from the manufacturer and should be consulted for specific coverage details.
