Detailed Product Features and Specifications

This Dynamite Friction rotor is a solid type rotor with a plain disc finish and a directional braking surface, optimized for the Ford Focus. The rotor’s drilled and slotted design helps to reduce brake fade by allowing gases and debris to escape, improving pad bite and overall braking consistency. The rotor measures 271 mm in outside diameter and 40.7 mm in height, with a nominal thickness of 11 mm and a discard thickness of 9 mm, ensuring it meets OEM specifications for safe replacement.

The rotor includes a rust resistant coating and a Geospec silver grey finish on the hat, which helps protect against corrosion and extends the rotor’s service life. The five bolt holes, each 13.7 mm in diameter, are arranged on a 108 mm bolt circle diameter, matching the Ford Focus hub specifications. The center hole diameter is 63.5 mm, ensuring proper fitment and alignment.

• Maintains consistent braking performance under normal and aggressive driving conditions

Installation Notes and Tips

Ensure the rotor is compatible with your specific Ford Focus model year and trim before installation. Clean the hub surface thoroughly to prevent rotor runout. Use proper torque specifications on the five lug nuts (13.7 mm diameter) to secure the rotor. Since this rotor features a directional braking surface, install it according to the indicated rotation direction for optimal performance. Inspect brake pads for wear and replace if necessary to ensure even contact with the rotor surface.

Quality Assurance

Dynamite Friction manufactures the 830-54066R rotor to meet or exceed OEM standards for fit, form, and function. The rust resistant coating and Geospec silver grey finish contribute to the rotor’s durability. While no specific warranty information is provided, Dynamite Friction products are generally subject to quality control processes to ensure reliable performance on Ford Focus vehicles.
