Product Line Details: 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 reduced brake fade. The cross-drilled surface allows for better gas and dust evacuation, while the vented rotor design promotes airflow to maintain optimal operating temperatures. This product line is suitable for drivers seeking consistent braking response in both street and light performance applications.

Technical Specifications and Features

This disc brake rotor features a vented design with pillar-style vanes that improve cooling efficiency. The rotor's cross-drilled surface helps dissipate heat and reduce brake pad glazing. The coated hat finish protects against corrosion, extending rotor life. The floating disc mounting system allows for slight rotor movement, reducing stress and improving brake feel. With a center hole diameter of 69 mm (2.717 inches) and five lug holes sized at 12.6 mm (0.496 inches), this rotor fits securely on the Mitsubishi Lancer hub assembly.

Applications and Problem Solving

• Reduces brake fade during aggressive driving or extended braking
• Improves heat dissipation to prevent rotor warping
• Minimizes brake dust buildup on rotor surface
• Enhances braking consistency in Mitsubishi Lancer vehicles
• Replaces worn or damaged factory rotors with a performance-oriented option

Installation Notes and Tips

• Ensure compatibility with Mitsubishi Lancer model year and trim before installation
• Check rotor discard thickness (29.8 mm) to confirm replacement necessity
• Use proper torque specifications for the 5 lug nuts on the 114.3 mm bolt circle
• Inspect brake pads and hardware during rotor replacement for optimal performance
• Follow manufacturer guidelines for bedding-in new rotors
