• Overall diameter of 319 mm and center hole diameter of 62 mm

Detailed Product Features and Specifications

This DFC Brake Rotor - Drilled and Slotted - Silver is a vented rotor, which means it has internal vanes to help dissipate heat more effectively during braking. The rotor’s surface is both drilled and slotted, a design that aids in removing brake dust, gases, and water from the contact area, improving braking performance under various conditions. The directional surface type ensures the slots and drilled holes are oriented to maximize water dispersion and pad bite.

The rotor features a plain disc finish with a zinc silver coating on the hat, providing rust resistance and extending the rotor’s service life. It has a nominal thickness of 28 mm and a discard thickness of 26 mm, which are critical measurements for maintaining safe braking performance. The rotor’s five bolt holes and stud/lug hole circle diameter of 114.3 mm match the factory specifications for the compatible Lexus and Toyota models.

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 rotors that combine drilled holes and slots with a corrosion-resistant finish. This product line is designed to provide consistent braking performance and durability for mid-size SUVs and crossovers, such as the Lexus RX and Toyota Highlander. The silver zinc coating on the rotor hat helps protect against rust, which is especially beneficial in regions with wet or salty road conditions.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Lexus RX330, RX350, RX400h, and Toyota Highlander
• Improves heat dissipation to reduce brake fade during extended braking
• Helps eliminate brake noise and vibration caused by uneven rotor surfaces
• Enhances wet weather braking performance by dispersing water from the rotor surface
• Prevents rust buildup on rotor hats to maintain proper wheel fitment and balance

Installation Notes and Tips

• Ensure rotor thickness is above the discard thickness of 26 mm before installation
• Clean rotor surface and hub mounting area to prevent uneven wear or vibration
• Use proper torque specifications for the 5 lug bolts with a 114.3 mm bolt circle diameter
• Check compatibility with Lexus Highlander and RX series models prior to installation
• Inspect brake pads and replace if worn to ensure optimal rotor performance
