Detailed Product Features and Specifications

This Dynamite Friction rotor features a vented design that helps dissipate heat more effectively during braking, reducing the risk of brake fade. The drilled and slotted surface improves water and debris evacuation, enhancing wet weather braking performance. The rotor’s directional surface ensures proper alignment for optimal braking response. With a nominal thickness of 42 mm and a discard thickness of 40.4 mm, it maintains structural integrity and safety throughout its service life.

The rotor’s hat is finished in zinc silver, providing corrosion resistance, while the entire rotor is coated with a rust-resistant layer to extend durability. It includes eight bolt holes with a 13 mm diameter and a bolt circle diameter of 145 mm, suitable for vehicles requiring this specific fitment. The overall diameter of 345 mm and height of 116.7 mm make it compatible with a range of applications requiring these dimensions.

DFC Brake Rotor - Drilled and Slotted - Silver Product Line

The DFC Brake Rotor - Drilled and Slotted - Silver line by Dynamite Friction focuses on rotors that combine drilled and slotted surfaces with corrosion-resistant finishes. This product line is designed to provide consistent braking performance under demanding conditions, with vented rotors that help manage heat buildup. The silver zinc finish adds protection against rust, making these rotors suitable for vehicles exposed to varying weather conditions.

Common Applications and Problem Solving

• Reduces brake fade caused by excessive heat during heavy braking
• Improves braking performance in wet or debris-prone environments
• Prevents rust and corrosion on the rotor surface for longer service life
• Maintains structural integrity with precise thickness specifications
• Ensures proper fitment with 8-bolt, 145 mm bolt circle diameter vehicles

Installation Notes and Tips

Ensure the rotor is installed with the directional surface oriented correctly according to the vehicle’s rotation. Verify bolt hole alignment with the vehicle’s hub using the 13 mm bolt hole diameter and 145 mm bolt circle diameter. Check rotor thickness before installation to confirm it is above the discard thickness of 40.4 mm. Proper torque specifications should be followed to avoid warping or uneven wear.

Quality Assurance and Warranty

Dynamite Friction manufactures this rotor to meet industry standards for durability and performance. The rust-resistant coating and zinc silver hat finish contribute to long-term reliability. Warranty information is available through the manufacturer and should be reviewed prior to purchase to confirm coverage details.
