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

The StopTech Sport Cross-Drilled Disc Brake Rotors line focuses on performance-oriented rotors designed to improve heat management and braking consistency. The cross-drilled surface pattern enhances cooling by allowing heat and gases to escape more efficiently, while the vented rotor construction promotes airflow. This combination helps maintain braking performance during spirited driving or repeated stops, making it suitable for Honda Civic, Civic del Sol, and CRX owners seeking a balance between daily driving and sportier use.

Technical Specifications and Features

This disc brake rotor features a nominal thickness of 0.827 inches (21.000 mm) and a discard thickness of 0.748 inches (19.000 mm), ensuring durability and longevity within specified wear limits. The rotor has an outside diameter of 9.449 inches (240.000 mm) and an overall height of 1.772 inches (45.000 mm). The hat is coated to resist corrosion, extending the rotor's service life.
