DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction is designed to provide enhanced braking efficiency through a combination of drilled holes and precision slots. These features improve heat dissipation and help evacuate brake dust and gases, reducing brake fade during demanding driving conditions. The directional surface design further optimizes performance by channeling airflow effectively across the rotor surface.

Detailed Product Description

This disc brake rotor features a nominal thickness of 20 mm with a discard thickness of 18 mm, ensuring a reliable service life before replacement is necessary. The rotor's 316 mm outside diameter and 63.5 mm height are engineered to match the braking system specifications of Subaru Impreza, WRX, and WRX STI models. The vented rotor design improves cooling by allowing air to flow between the rotor surfaces, reducing heat buildup during braking. The rotor hat is finished in a rust-resistant Geospec silver grey coating, which helps prevent corrosion and extends the rotor's lifespan. The 5-bolt hole pattern with a 114.3 mm bolt circle diameter and 12.8 mm bolt hole diameter ensures precise fitment and secure mounting.

Applications and Problem Solving

• Improves braking performance for Subaru Impreza, WRX, and WRX STI vehicles
• Reduces brake fade during aggressive or prolonged braking
• Helps prevent rotor warping caused by excessive heat
• Minimizes brake dust accumulation for cleaner braking surfaces
• Protects against rust and corrosion with a specialized coating

Installation Notes and Tips

Ensure the rotor is installed on compatible Subaru Impreza, WRX, or WRX STI models matching the 5-lug, 114.3 mm bolt circle pattern. Verify the rotor thickness before installation; replace if below the discard thickness of 18 mm. Properly torque lug nuts to manufacturer specifications to avoid rotor damage. It is recommended to inspect brake pads and hardware during rotor replacement for optimal braking system performance.

Quality Assurance

Dynamite Friction manufactures the 830-13022L rotor to meet strict quality standards for fitment and durability. The rust-resistant coating and vented design contribute to long-term reliability. Warranty information is available through the manufacturer or authorized distributors.
