Detailed Product Features and Specifications

This Dynamite Friction rotor is designed with a vented construction to improve heat dissipation during braking, reducing the risk of brake fade. The drilled and slotted surface pattern helps to evacuate gases, dust, and water, maintaining consistent braking performance under various conditions. The directional surface ensures proper rotation alignment for optimal efficiency.

The rotor's nominal thickness is 24 mm, with a discard thickness of 22 mm, indicating when replacement is necessary to maintain safety and performance. The rotor measures 294 mm in outside diameter and 48.5 mm in height, fitting precisely on Subaru Crosstrek and Impreza models with a 5-lug bolt pattern, 13 mm bolt hole diameter, and 100 mm bolt circle diameter. The hat section features a Geospec silver grey finish, adding corrosion resistance along with the rust resistant coating applied to the entire rotor.

About the DFC Geoperformance Rotor - Drilled and Slotted Line

The DFC Geoperformance Rotor - Drilled and Slotted product line by Dynamite Friction focuses on rotors that combine drilled holes and slots with vented construction. This design aims to improve braking response and heat management, making it suitable for drivers who require reliable stopping power in demanding conditions. The rust resistant coating and Geospec hat finish contribute to longer rotor life and reduced maintenance.

Applications and Problem Solving

• Improves braking performance for Subaru Crosstrek and Impreza vehicles
• Reduces brake fade caused by heat buildup during extended braking
• Helps prevent water and debris accumulation on the rotor surface
• Minimizes rust and corrosion for longer rotor lifespan
• Maintains consistent braking feel with directional surface design

Installation Notes and Tips

Ensure the rotor is installed with the directional surface rotating correctly according to the vehicle’s forward motion. Verify bolt hole alignment with the 5-lug pattern and 100 mm bolt circle diameter. Measure rotor thickness before installation to confirm it meets or exceeds the nominal thickness of 24 mm. Replace the rotor if thickness is at or below the discard thickness of 22 mm. Clean the rotor surface before installation to remove any protective coatings or residues.

Quality Assurance and Warranty

Dynamite Friction manufactures the 830-13037L rotor to meet industry standards for fitment and performance on Subaru Crosstrek and Impreza models. The rust resistant coating and Geospec silver grey hat finish provide additional protection against corrosion. Warranty details are subject to the manufacturer’s terms and should be verified at the time of purchase.
