About the DFC Geoperformance Rotor - Drilled and Slotted Line

The DFC Geoperformance Rotor - Drilled and Slotted line by Dynamite Friction focuses on delivering rotors that balance performance and durability. Featuring a directional surface with both drilled holes and slots, these rotors help reduce brake fade by improving heat dissipation and removing debris from the brake pad surface. The rust resistant coating and Geospec silver grey hat finish further protect the rotor from environmental wear, making it suitable for daily driving and moderate performance applications.

Product Details and Specifications

This disc brake rotor is designed with a nominal thickness of 18 mm and a discard thickness of 16.5 mm, ensuring safe and effective braking performance throughout its service life. The rotor’s directional slotted and drilled surface enhances braking efficiency by allowing gases and dust to escape, which helps maintain consistent pad contact. The rotor’s dimensions, including a 338 mm outside diameter and 39.7 mm height, are tailored to fit Lexus RX350, RX350L, RX450h, and RX450hL models with a 5-lug bolt pattern and 114.3 mm bolt circle diameter.

Common Applications and Problem Solving

• Reduces brake fade during extended or aggressive braking
• Improves heat dissipation to prevent rotor warping
• Minimizes brake dust buildup on pads and rotors
• Protects against rust and corrosion for longer rotor life
• Restores braking performance on Lexus RX350 and RX450h models

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify that the rotor thickness is above the discard thickness of 16.5 mm to maintain safety standards. Use proper torque specifications for the 5-lug bolt pattern with a 114.3 mm bolt circle diameter. It is recommended to replace brake pads when installing new rotors to optimize braking performance and rotor longevity.
