About StopTech Sport Cross-Drilled Disc Brake Rotors

The StopTech Sport Cross-Drilled Disc Brake Rotors line is designed to provide reliable braking performance for street and light track use. The cross-drilled surface pattern improves ventilation and helps dissipate heat more effectively than standard rotors. This reduces the risk of brake fade during aggressive driving or extended braking periods. The vented rotor design with straight vanes further enhances airflow, maintaining optimal rotor temperatures. The coated hat finish offers protection against rust and corrosion, ensuring durability over time.

Technical Details and Compatibility

The StopTech rotor 128.40057R is specifically compatible with Acura and Honda vehicles such as the Civic, CR-V, CSX, ILX, and RSX. It features a floating disc mounting system that allows slight movement between the rotor and hub, improving alignment and reducing stress on the braking components. The rotor has a 5-lug hole pattern with a 114.3 mm bolt circle diameter and 12.5 mm stud hole diameter, fitting factory specifications for the listed models. The nominal thickness is 0.984 inches (25.000 mm), with a discard thickness of 0.906 inches (23.000 mm), indicating when the rotor should be replaced to maintain safe braking performance.

Common Applications and Problem Solving

• Reduces brake fade during extended or aggressive braking
• Improves heat dissipation to prevent rotor warping
• Minimizes corrosion with coated hat finish for longer service life
• Enhances braking consistency for Acura and Honda Civic, CR-V, CSX, ILX, and RSX models
• Addresses vibration issues caused by uneven rotor wear or overheating

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Use proper torque specifications for mounting bolts to avoid rotor distortion
• Inspect brake pads and replace if worn to ensure optimal rotor performance
• Clean rotor surface before installation to remove any protective coatings or debris
• Verify compatibility with vehicle ABS systems; this rotor does not include an ABS tone ring
