About the StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors Line

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide enhanced braking performance through improved rotor cooling and debris removal. The combination of cross-drilled holes and precision slots helps maintain consistent pad contact and reduces the risk of brake fade during demanding driving conditions. This product line is well-suited for drivers seeking a balance between everyday usability and sportier braking response.

Detailed Product Description

This disc brake rotor features a vented design with straight vanes that promote efficient airflow to dissipate heat generated during braking. The rotor’s slotted and drilled surface improves pad bite and helps evacuate gases and dust, which can accumulate and reduce braking efficiency. The coated hat finish protects the rotor’s central hub from corrosion, ensuring durability over time. With a floating disc mounting system and two additional miscellaneous holes, this rotor accommodates thermal expansion and reduces the risk of warping. The rotor weighs approximately 16 lbs (7.27 kg), balancing strength and weight for optimal performance.

Common Applications and Problem Solving

• Reduces brake fade during extended or aggressive braking
• Improves heat dissipation to prevent rotor warping
• Enhances braking response and pad bite on Lexus Avalon and Toyota Camry models
• Minimizes brake dust buildup for cleaner braking surfaces
• Addresses corrosion issues with coated hat finish

Installation Notes and Tips

• Ensure compatibility with your vehicle’s make and model, specifically Lexus Avalon, Toyota Camry, ES300, Sienna, or Solara
• Check rotor thickness before installation; discard if below 1.024 inches (26.000 mm)
• Use proper torque specifications for the 5 lug nuts on the 4.5 inch bolt circle
• Inspect brake pads and hardware during rotor replacement for optimal performance
• Follow manufacturer guidelines for bedding-in new rotors and pads
