About StopTech Sport Cross-Drilled Disc Brake Rotors

The StopTech Sport Cross-Drilled Disc Brake Rotors line is designed to provide enhanced braking performance through improved heat management and durability. The cross-drilled surface reduces brake fade by allowing gases and heat to escape more efficiently during heavy braking. The vented rotor design with straight vanes further aids in cooling, making these rotors suitable for both street and light performance driving. The coated hat finish helps protect against rust and corrosion, maintaining rotor integrity over time.

Detailed Product Description

This StopTech rotor 128.40057L features a vented design with straight vanes that promote airflow to reduce heat buildup during braking. The cross-drilled surface pattern improves water and gas evacuation, which helps maintain consistent brake pad contact and reduces the risk of brake fade. The rotor’s floating disc mounting allows for slight movement to accommodate thermal expansion, minimizing warping and extending rotor life. With a coated hat finish, this rotor resists corrosion, which is especially beneficial in humid or wet environments. The rotor measures 11.811 inches (300 mm) in diameter and 1.854 inches (47.1 mm) in overall height, fitting vehicles with a 5-lug pattern and 114.3 mm bolt circle diameter.

Compatible Vehicles and Applications

• Acura Civic, CR-V, CSX, ILX, RSX models requiring a 300 mm vented rotor
• Honda Civic, CR-V, CSX, ILX, RSX models with 5 lug/stud holes and 114.3 mm bolt circle
• Replacement for worn or warped rotors to restore braking performance
• Upgrading factory rotors for improved heat dissipation and fade resistance
• Suitable for drivers seeking reliable braking under normal and spirited driving conditions

Installation Notes and Tips

• Ensure compatibility with vehicle make, model, and year before installation
• Check rotor thickness and discard thickness to confirm replacement necessity
• Use proper torque specifications for mounting bolts to avoid rotor distortion
• Inspect brake pads and hardware during rotor replacement for optimal performance
• Follow manufacturer guidelines for bedding-in new rotors and pads
