Dynamite Friction 830-13009L Disc Brake Rotor - Front Left

Overview of Dynamite Friction DFC Geoperformance Rotor

The Dynamite Friction DFC Geoperformance Rotor - Drilled and Slotted (part number 830-13009L) is engineered for reliable braking performance on select Saab and Subaru models. Designed with a vented, directional surface, this rotor enhances heat dissipation and braking consistency for vehicles like the Subaru BRZ and Saab 9-2X.

• Nominal thickness: 24 mm with a discard thickness of 22 mm
• Vented disc type with drilled and slotted surface for improved cooling
• Directional brake surface optimized for performance braking
• Rust resistant coating to extend rotor life
• Geospec silver grey hat finish for corrosion resistance and durability
• Five bolt holes with 12.8 mm diameter and 100 mm bolt circle diameter
• Overall diameter of 277 mm and height of 56.7 mm

Detailed Product Features and Specifications

This disc brake rotor features a vented design that promotes efficient heat dissipation, reducing the risk of brake fade during extended use. The drilled and slotted surface pattern helps to evacuate gases, dust, and water, maintaining consistent pad contact and improving braking response. The directional surface type is engineered to optimize braking performance in the intended rotation direction, which is critical for vehicles such as the Subaru Forester and Legacy.

The rotor’s nominal thickness of 24 mm ensures structural integrity, while the discard thickness of 22 mm indicates the minimum safe thickness before replacement is necessary. The rotor’s hat is finished in Geospec silver grey, providing additional corrosion resistance, complemented by a rust resistant coating on the disc surface. The five bolt holes with a 12.8 mm diameter and 100 mm bolt circle diameter match the factory specifications for compatible Saab and Subaru models, including the Impreza and Outback.

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 thermal management and surface design. This product line incorporates vented rotors with directional drilled and slotted surfaces to improve braking efficiency and rotor longevity. The 830-13009L rotor is a part of this line, offering a balance of performance and durability tailored for specific Saab and Subaru vehicles.

Applications and Problem Solving

• Reduces brake fade during high-demand driving conditions
• Improves braking response in wet or dusty environments
• Minimizes rotor warping through enhanced heat dissipation
• Prevents rust and corrosion for longer service life
• Maintains consistent pad contact with directional surface design

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented according to the vehicle’s rotation direction for optimal performance. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt, 100 mm bolt circle pattern. Measure rotor thickness before installation to confirm it meets or exceeds the discard thickness of 22 mm. Proper torque specifications should be followed to avoid rotor distortion.

Quality Assurance

Dynamite Friction rotors undergo rigorous quality control to meet OEM standards. The rust resistant coating and Geospec silver grey hat finish contribute to durability and corrosion resistance. While no specific warranty information is provided, the product is manufactured to maintain consistent braking performance and safety on compatible Saab and Subaru models.
