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

The StopTech Sport Cross-Drilled Disc Brake Rotors line focuses on performance-oriented rotors featuring cross-drilled surfaces to aid in heat and gas dissipation during braking. This design helps maintain consistent brake pad contact and reduces the risk of brake fade. The vented rotor construction with pillar-style vanes further improves airflow, making these rotors suitable for spirited driving and daily use on Mitsubishi Lancer vehicles.

Technical Specifications and Features

This disc brake rotor features a vented design with pillar-style vanes that promote efficient cooling. The cross-drilled surface type enhances heat dissipation and helps prevent gas buildup between the rotor and brake pad. The rotor has a coated hat finish to resist corrosion and extend service life. Key dimensions include an outside diameter of 12.992 inches (330 mm), nominal thickness of 0.866 inches (22 mm), and an overall height of 2.327 inches (59.1 mm). It mounts with 5 lug holes on a 4.5 inch (114.3 mm) bolt circle diameter, compatible with Mitsubishi Lancer brake assemblies. The rotor does not include ABS tone rings or bearings.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mitsubishi Lancer
• Improves heat management during aggressive braking
• Reduces brake fade caused by gas buildup on rotor surface
• Addresses corrosion issues with coated hat finish
• Restores proper rotor thickness for safe braking performance

Installation Notes and Tips

Ensure the rotor thickness is within discard limits before installation; discard thickness is 0.787 inches (20 mm). Clean the rotor surface to remove any protective coatings before mounting. Verify bolt hole alignment with the 5-lug, 4.5 inch (114.3 mm) bolt circle pattern on the Mitsubishi Lancer. Use proper torque specifications for lug nuts to avoid rotor warping. This rotor is designed for floating/dih disc mounting and does not include bearings or ABS tone rings, so reuse existing components as needed.

Quality Assurance and Warranty

StopTech Sport Cross-Drilled Disc Brake Rotors are manufactured to meet OEM specifications for fit and function on Mitsubishi Lancer vehicles. The coated hat finish provides corrosion resistance to extend rotor life. While specific warranty details are not provided, StopTech products typically undergo rigorous quality control to ensure durability and consistent braking performance.
