• Compatible with Subaru Legacy and Outback vehicles
• Directional slotted and drilled surface for improved brake pad contact and cooling
• Solid rotor construction with a nominal thickness of 10 mm and discard thickness of 8.5 mm
• Rust resistant coating with Geospec silver grey hat finish for corrosion protection
• 5 bolt holes with 12.94 mm diameter and 100 mm bolt circle diameter
• Overall diameter of 274 mm and height of 67.6 mm

Detailed Product Features and Specifications

This Dynamite Friction rotor is designed with a solid disc type, providing consistent braking performance for Subaru Legacy and Outback models. The rotor’s surface is both drilled and slotted, which helps to reduce brake fade by allowing gases and debris to escape while improving pad bite. The directional brake surface ensures optimal rotation alignment for effective heat dissipation.

The rotor measures 274 mm in outside diameter and 67.6 mm in height, with a nominal thickness of 10 mm and a discard thickness of 8.5 mm, indicating when replacement is necessary. The hat section features a Geospec silver grey finish that offers rust resistance, extending the rotor’s service life. The 5-lug bolt pattern with 12.94 mm diameter holes and a 100 mm bolt circle diameter matches the factory specifications for the specified Subaru models.

About the DFC Geoperformance Rotor - Drilled and Slotted Line

The DFC Geoperformance Rotor - Drilled and Slotted product line focuses on delivering rotors with enhanced surface designs to improve braking efficiency and thermal management. This line combines drilled holes and slots in a directional pattern to optimize pad contact and reduce heat buildup, which is critical for maintaining consistent braking performance under demanding conditions.

Applications and Problem Solving

• Reduces brake fade during extended or aggressive braking
• Improves heat dissipation to prevent rotor warping
• Helps maintain consistent brake pad contact for smoother stops
• Protects against rust and corrosion for longer rotor life
• Compatible with Subaru Legacy and Outback brake systems requiring 5-lug, 274 mm rotors

Installation Notes and Tips

Ensure the rotor is installed with the directional surface rotating correctly according to the vehicle’s wheel rotation. Verify bolt hole alignment with the 5-lug pattern and 100 mm bolt circle diameter. Check rotor thickness before installation to confirm it meets or exceeds the discard thickness of 8.5 mm. Proper torque specifications should be followed to avoid rotor damage or uneven wear.

Quality Assurance

Dynamite Friction rotors are manufactured to meet OEM standards for fitment and performance. The rust resistant coating and precise machining contribute to durability and reliable braking. Warranty information is available through the manufacturer or authorized distributors.
