• Five bolt holes with 14.7 mm diameter and 114.3 mm bolt circle diameter

Detailed Product Features and Specifications

The DFC Brake Rotor - Drilled and Slotted - Silver is constructed with a vented rotor design that promotes airflow to dissipate heat effectively during braking. The rotor’s surface combines drilled holes and slots arranged directionally to help evacuate gases, dust, and water, improving braking consistency and reducing the risk of brake fade. The rotor’s nominal thickness is 19.1 mm, with a discard thickness of 17.4 mm, ensuring a long service life before replacement is necessary.

The rotor measures 300 mm in outside diameter and 35.2 mm in overall height, fitting precisely on Ford Mustang models with a 5-lug bolt pattern. The zinc silver coating on the hat area provides rust resistance, extending the rotor’s durability in various driving environments. The bolt hole diameter and stud/lug hole diameter are both 14.7 mm, with a bolt circle diameter of 114.3 mm, matching factory specifications for proper fitment.

About the DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line from Dynamite Friction focuses on delivering rotors that balance performance and durability. This product line features rotors with drilled and slotted surfaces designed to improve braking efficiency and heat dissipation. The silver zinc coating enhances corrosion resistance, making these rotors suitable for drivers who require consistent braking performance and longevity on their Ford Mustang.

Applications and Problem Solving

• Reduces brake fade during aggressive or repeated braking
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust buildup for cleaner operation
• Prevents rust and corrosion on the rotor hat for extended service life
• Maintains consistent braking performance under high heat conditions

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify that the rotor thickness meets or exceeds the discard thickness of 17.4 mm to maintain safe braking performance. Use proper torque specifications for the 5-lug bolt pattern with 14.7 mm diameter holes and a 114.3 mm bolt circle diameter. It is recommended to inspect brake pads and other braking components during rotor replacement to ensure optimal system performance.

Quality Assurance

Dynamite Friction manufactures the 631-54058L rotor to meet OEM specifications for Ford Mustang vehicles. The rust-resistant zinc silver finish and vented rotor design contribute to durability and reliable braking. While no specific warranty information is provided, the rotor is engineered to maintain performance within the specified thickness limits and fitment requirements.
