Detailed Product Features and Specifications

This DFC Brake Rotor features a vented design that improves airflow to reduce heat buildup during braking, which helps maintain consistent stopping power. The drilled and slotted surface enhances water and debris evacuation, reducing brake fade and improving pad bite. The rotor’s nominal thickness is 28 mm, with a discard thickness of 25 mm, ensuring a clear service life indicator for replacement. The zinc silver coating on the hat provides corrosion resistance, extending the rotor’s durability in various driving conditions.

The rotor’s directional surface is designed to optimize braking performance by channeling gases and dust away from the pad contact area. With five bolt holes and a bolt circle diameter of 114.3 mm, it fits securely on compatible Lexus and Toyota vehicles. The overall diameter of 328 mm and center hole diameter of 62 mm are engineered to match factory specifications for a precise fit.

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

Common Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup
• Improves braking performance in wet or dusty conditions
• Minimizes rotor warping and extends rotor life
• Helps maintain consistent brake pad contact and bite
• Prevents rust and corrosion on rotor surfaces

Installation Notes and Tips

Ensure the rotor is installed on compatible Lexus or Toyota models such as the Highlander, NX200t, or RX350. Verify the bolt pattern matches the vehicle’s hub (5 lug holes, 114.3 mm bolt circle diameter). Clean the hub surface before installation to prevent uneven rotor seating. Torque lug nuts to manufacturer specifications and inspect brake pads for wear during rotor replacement.

Quality Assurance and Warranty
