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

The StopTech Select Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide enhanced braking performance for street-driven vehicles that require improved heat management and consistent pedal feel. The combination of cross-drilled holes and precision slots helps to evacuate gases, dust, and water from the rotor surface, which is particularly beneficial for Subaru Impreza and Legacy drivers seeking reliable braking in various driving conditions.

Technical Specifications and Fitment

This disc brake rotor is specifically compatible with Subaru Impreza and Legacy models, ensuring proper fit and function. The rotor is vented with straight vanes to optimize airflow and cooling. It does not include ABS tone rings or bearings, so these components must be reused or sourced separately. The rotor’s mounting features a floating/dih disc mounting style with two miscellaneous holes for additional mounting stability.

Common Applications and Problem Solving

• Reduces brake fade caused by overheating during aggressive driving or towing
• Improves braking response and pedal feel on Subaru Impreza and Legacy vehicles
• Helps prevent rotor surface glazing and brake pad deposits
• Enhances water and debris evacuation for consistent braking in wet conditions
• Addresses uneven rotor wear and vibration issues associated with stock rotors

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (0.630 inches) before installation
• Use proper torque specifications for the 5-lug mounting pattern with 100 mm bolt circle diameter
• Inspect and clean hub surface to ensure proper rotor seating on the 2.283 inch center hole
• Reinstall or replace bearings and ABS tone rings as needed, since they are not included
• Follow manufacturer’s recommended break-in procedure for optimal rotor and pad performance
