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 enhanced braking performance through improved rotor cooling and debris removal. The combination of cross-drilled holes and precision slots helps maintain consistent brake pad contact and reduces the risk of brake fade during aggressive driving or track use. This rotor line features a coated hat finish to resist corrosion and a vented design to optimize airflow, making it suitable for performance-oriented Subaru Impreza and WRX STI vehicles.

Technical Specifications and Features

This disc brake rotor features a vented design with straight vanes to maximize airflow and heat dissipation. The rotor's overall height measures 53.1 mm (2.091 inches), with a center hole diameter of 58 mm (2.283 inches) to ensure proper fitment. The floating disc mounting system allows for thermal expansion, reducing the risk of warping under high temperatures. The rotor includes two miscellaneous holes and is designed for 5 lug/stud holes with a diameter of 12.9 mm (0.508 inches).

Applications and Problem Solving

• Reduces brake fade during high-performance driving or track use
• Improves heat dissipation to extend rotor and pad life
• Helps prevent brake pad glazing and uneven wear
• Minimizes corrosion with coated hat finish
• Maintains consistent braking performance in Subaru Impreza and WRX STI models

Installation Notes and Tips

• Ensure compatibility with Subaru Impreza and WRX STI before installation
• Check rotor thickness and discard thickness to confirm rotor condition
• Use proper torque specifications for the 5 lug bolts on the 114.3 mm bolt circle diameter
• Inspect brake pads and calipers during rotor replacement for optimal performance
• Follow manufacturer guidelines for bedding-in new rotors and pads
