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

The StopTech Select Sport Cross-Drilled & Slotted Disc Brake Rotors are part of StopTech's Select Sport line, designed to provide enhanced braking performance for street-driven vehicles. This product line focuses on improving rotor cooling and pad bite through precision cross-drilling and slotting patterns, which help evacuate heat, dust, and gases generated during braking. The vented rotor construction further aids in maintaining optimal operating temperatures, making these rotors suitable for Mitsubishi Lancer owners seeking a balance between daily driving and spirited performance.

Technical Specifications and Features

These disc brake rotors have a nominal thickness of 0.866 inches (22.000 mm) and a discard thickness of 0.787 inches (20.000 mm), ensuring a durable lifespan before replacement is necessary. The overall height measures 2.327 inches (59.100 mm), and the outside diameter is 12.992 inches (330.000 mm), matching OEM dimensions for proper fitment. The rotor features a 5-stud lug pattern with a 4.5 inch (114.300 mm) bolt circle diameter and a center hole diameter of 3.150 inches (80.000 mm). The vented design incorporates pillar-style vanes to optimize airflow and cooling efficiency. Note that this rotor does not include an ABS tone ring or bearings.

Applications and Problem Solving

• Reduces brake fade during aggressive or prolonged braking
• Improves heat dissipation to prevent rotor warping
• Enhances braking response and pad bite with slotted and drilled surface
• Addresses uneven rotor wear and brake noise issues
• Compatible replacement for worn or damaged Mitsubishi Lancer rotors

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the discard thickness of 0.787 inches (20.000 mm). Clean the rotor surface to remove any protective coatings or debris prior to mounting. Verify the 5-lug bolt pattern and 4.5 inch (114.300 mm) bolt circle diameter match the vehicle specifications. Proper torque specifications should be followed when securing the rotor to avoid warping. Since bearings and ABS tone rings are not included, reuse existing components or replace separately as needed.
