Detailed Product Description

This DFC Geoperformance Rotor - Drilled and Slotted from Dynamite Friction is designed to meet the braking demands of Lexus and Toyota SUVs including the Highlander and RX series. The rotor features a directional surface pattern combining drilled holes and slots, which helps evacuate gases, dust, and water from the braking surface. This design improves pad contact and reduces the risk of brake fade under heavy braking conditions.

The rotor is vented, allowing air to flow between the rotor faces to dissipate heat more effectively than solid rotors. This is critical for maintaining consistent braking performance during prolonged or aggressive driving. The rotor’s rust resistant coating helps prevent corrosion, which can degrade braking efficiency and rotor lifespan.

With a nominal thickness of 28 mm and a discard thickness of 26 mm, this rotor provides a balance between durability and performance. The Geospec silver grey finish on the hat adds corrosion resistance and a clean appearance. The rotor’s 5 bolt holes and 114.3 mm bolt circle diameter ensure a precise fit for compatible Lexus and Toyota models.

Applications and Problem Solving

• Replacement rotor for worn or warped disc brakes on Lexus Highlander and Toyota RX models
• Improves braking performance by reducing heat buildup and brake fade
• Addresses rotor corrosion issues with rust resistant coating
• Enhances brake pad bite and reduces brake noise with drilled and slotted surface
• Maintains consistent braking under heavy load or towing conditions

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (26 mm) before installation
• Clean hub surface and mounting points to prevent rotor runout
• Use proper torque specifications for the 5 lug bolts (bolt circle diameter 114.3 mm)
• Check brake pads for wear and replace if necessary to optimize rotor performance
• Follow vehicle manufacturer guidelines for brake system maintenance
