Detailed Product Description

This DFC Geoperformance Rotor - Drilled and Slotted is designed to meet the specific braking requirements of Subaru models such as the BRZ, Forester, Impreza, Legacy, Outback, and WRX. The rotor’s 286 mm outside diameter and 10 mm nominal thickness provide a robust braking surface, while the 8.5 mm discard thickness indicates when replacement is necessary to maintain safety and performance. The solid rotor construction combined with a directional slotted and drilled surface helps improve heat dissipation and reduce brake fade during demanding driving conditions.

The rotor’s hat is finished in Geospec silver grey, offering corrosion resistance along with a rust resistant coating applied to the entire rotor surface. The 5 bolt holes with a 13 mm diameter and 100 mm bolt circle diameter ensure precise fitment and secure mounting. This rotor is engineered to maintain consistent braking performance and durability for Subaru vehicles requiring this specific part number 830-13021L.

DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on delivering rotors with enhanced surface designs to improve braking efficiency. The drilled and slotted pattern on this rotor aids in venting gases and debris from the brake pad surface, which can help maintain consistent braking under various driving conditions. This product line is tailored for drivers seeking rotors that balance performance and durability without compromising fitment accuracy.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Subaru BRZ, Forester, Impreza, Legacy, Outback, and WRX
• Improves heat dissipation to reduce brake fade during extended braking
• Helps prevent rust and corrosion with protective coating
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Maintains braking performance with directional drilled and slotted design

Installation Notes and Tips

Ensure the rotor surface is clean and free of debris before installation. Verify the bolt hole pattern and center hole diameter match your vehicle’s hub assembly. Use proper torque specifications for the 5 lug bolts to avoid rotor warping. It is recommended to replace brake pads when installing new rotors to ensure optimal braking performance.

Quality Assurance

Dynamite Friction rotors are manufactured to meet OEM specifications for fit and function. The rust resistant coating extends rotor life by protecting against corrosion. While no specific warranty information is provided, adherence to installation guidelines and regular maintenance will help ensure reliable braking performance with part number 830-13021L on compatible Subaru models.
