Detailed Product Features and Specifications

This disc brake rotor features a nominal thickness of 0.980 inches (24.9 mm) and a discard thickness of 0.906 inches (23.0 mm), ensuring precise wear limits for safe operation. The rotor's outside diameter measures 12.205 inches (310 mm), with an overall height of 1.787 inches (45.4 mm). It includes a 2.528 inch (64.2 mm) center hole diameter and a mounting bolt hole circle diameter of 4.5 inches (114.3 mm), designed to fit Acura TL brake assemblies. The rotor is vented with pillar-style vanes to optimize airflow and cooling. The floating disc mounting system accommodates thermal expansion, reducing the risk of warping during heavy braking. The hat section is coated to resist corrosion and extend service life. This rotor weighs approximately 17.5 lbs (7.95 kgs) and does not include ABS tone rings or bearings.

About 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 durability. Cross-drilled rotors like the 128.40062L help dissipate heat and gases generated during braking, which can improve pedal feel and reduce brake fade. The vented design further aids in cooling, making these rotors suitable for drivers who demand consistent braking performance in both street and light track conditions.

Common Applications and Problem Solving

• Reduces brake fade during aggressive driving or towing
• Improves heat dissipation to prevent rotor warping
• Addresses corrosion issues with coated hat finish
• Enhances braking response for Acura TL vehicles
• Replaces worn or damaged factory rotors with precise fitment

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness before installation
• Use proper torque specifications for mounting bolts on 5-lug Acura TL hubs
• Inspect brake pads and calipers for wear when replacing rotors
• Clean rotor surface with brake cleaner before installation to remove any protective coatings
• Check for ABS sensor clearance as this rotor does not include an ABS tone ring
