Details on StopTech Sport Cross-Drilled Disc Brake Rotors

The StopTech Sport Cross-Drilled Disc Brake Rotors line is designed to provide enhanced braking performance through advanced rotor technology. The cross-drilled surface pattern improves ventilation and helps dissipate heat and brake gases more effectively than standard rotors. This particular rotor, part number 128.40023L, features a vented design with straight vanes that promote airflow, reducing the risk of brake fade during aggressive driving or extended braking. The coated hat finish offers protection against corrosion, extending the rotor's service life. The floating disc mounting system allows for slight movement between the rotor and hub, which helps maintain better rotor alignment and reduces stress on the braking components.

Technical Specifications and Fitment

This disc brake rotor has a nominal thickness of 0.827 inches (21.000 mm) and a discard thickness of 0.748 inches (19.000 mm), ensuring it meets OEM standards for durability and performance. The overall height measures 1.772 inches (45.000 mm), and the outside diameter is 9.449 inches (240.000 mm). It includes four stud/lug holes with a diameter of 0.504 inches (12.800 mm) arranged on a 3.937 inch (100.000 mm) bolt circle diameter. The center hole diameter is 2.402 inches (61.000 mm). This rotor is compatible with Honda Civic, Civic del Sol, and CRX models, making it a direct replacement part for these vehicles.

Common Applications and Problem Solving

• Reduces brake fade during high-performance or spirited driving
• Improves heat dissipation to prevent rotor warping
• Minimizes brake dust buildup with cross-drilled design
• Enhances braking consistency under heavy load or repeated stops
• Replaces worn or damaged rotors to restore braking efficiency

Installation Notes and Tips

When installing the StopTech Sport Cross-Drilled Disc Brake Rotor 128.40023L, ensure the rotor is mounted on a clean, rust-free hub surface to maintain proper alignment. Use the floating disc mounting system as intended to allow for thermal expansion and rotor movement. Verify that the rotor thickness is above the discard thickness of 0.748 inches (19.000 mm) before installation. It is recommended to replace brake pads simultaneously to ensure optimal braking performance. No bearings or ABS tone ring are included with this rotor, so verify compatibility with your vehicle's existing components.
