Product Line Details: StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide improved braking performance for street and light track use. Featuring a combination of cross-drilled holes and precision slots, these rotors help maintain consistent brake pad contact and reduce gas buildup during braking. The vented rotor design further aids in heat management, making them suitable for Acura and Honda vehicles requiring reliable stopping power under varied driving conditions.

Technical Specifications and Features

This disc brake rotor features a vented design with straight vanes to optimize airflow and cooling. The rotor’s surface is both slotted and cross-drilled, which assists in removing brake dust, water, and gases that can reduce braking efficiency. The coated hat finish protects against corrosion, extending the rotor’s service life. The floating disc mounting system allows for slight movement between the rotor and hub, improving alignment and reducing stress on the braking components.

Common Applications and Problem Solving

• Reduces brake fade during extended or aggressive braking
• Improves heat dissipation to prevent rotor warping
• Enhances braking performance in wet or dusty conditions
• Minimizes brake dust buildup on rotor surface
• Provides consistent pedal feel and stopping power for Acura and Honda models

Installation Notes and Tips

• Ensure compatibility with Acura and Honda Accord Crosstour, CR-V, Crosstour, and RDX models before installation
• Check rotor thickness and discard thickness to confirm rotor condition during replacement
• Use proper torque specifications for the five lug bolts on the 4.5 inch bolt circle diameter
• Inspect brake pads and calipers for wear or damage when replacing rotors
• Follow manufacturer guidelines for bedding-in new rotors and pads
