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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to improve braking efficiency by combining cross-drilled holes and precision slots. This design helps to reduce brake fade by allowing gases and heat to escape more effectively during heavy braking. The vented rotor construction further aids in heat dissipation, making these rotors suitable for both street and light performance driving applications on Subaru Impreza and Legacy vehicles.

Technical Specifications and Features

These rotors have an overall height of 67.5 mm (2.657 inches) and a nominal drum diameter of 170 mm (6.693 inches). The rotor features a floating/dih disc mounting style with straight vane design to optimize airflow and cooling. The slotted and drilled surface type enhances pad bite and helps maintain clean contact surfaces. Note that these rotors do not include ABS tone rings or bearings.

Common Applications and Problem Solving

• Reduces brake fade during aggressive or repeated braking
• Improves heat dissipation to prevent rotor warping
• Enhances braking response and pad bite on Subaru Impreza and Legacy
• Helps maintain consistent braking performance under demanding conditions
• Addresses rotor surface glazing and brake dust buildup

Installation Notes and Tips

• Ensure compatibility with Subaru Impreza and Legacy models before installation
• Check rotor thickness and discard thickness to confirm suitability
• Use proper torque specifications for the 5 lug bolts on the 100 mm bolt circle
• Inspect brake pads and calipers during rotor replacement for optimal performance
• Follow manufacturer guidelines for bedding in new rotors and pads
