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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line focuses on performance-oriented rotors that combine cross-drilled holes and precision slots. This design improves brake pad bite and helps evacuate heat and debris from the rotor surface. The vented rotor construction further enhances cooling, making these rotors suitable for both street and light track use. The coated hat finish provides additional protection against rust, maintaining rotor integrity over time.

Technical Specifications and Features

This disc brake rotor features a vented design with straight vanes to optimize airflow and cooling. The rotor's outside diameter measures 11.720 inches (297.7 mm), with an overall height of 4.524 inches (114.9 mm). It has a nominal thickness of 1.185 inches (30.1 mm) and a discard thickness of 1.120 inches (28.45 mm), ensuring durability and serviceability. The rotor mounts using a 5-lug pattern with a 4.5-inch bolt circle diameter and 0.500-inch stud thread diameter. Note that this rotor does not include an ABS tone ring or bearings.

Compatible Vehicles and Applications

• Ford Colony Park
• Ford LTD
• Ford Thunderbird
• Lincoln Continental
• Mercury Marauder
• Mercury Marquis

These rotors are designed to replace factory disc brake rotors on the above models, providing consistent braking performance and improved heat management.

Common Issues Addressed by This Rotor

• Brake fade caused by excessive heat buildup during braking
• Uneven rotor wear leading to vibration or noise
• Corrosion and rust on rotor surfaces reducing braking efficiency
• Poor brake pad bite due to glazed or smooth rotor surfaces
• Reduced cooling efficiency in stock solid rotors

Installation Notes and Tips

Ensure the rotor thickness is within the nominal and discard specifications before installation. The coated hat finish should be handled carefully to avoid damage. This rotor requires a 5-lug wheel hub with a 4.5-inch bolt circle diameter and 0.500-inch stud thread diameter. Bearings and seals are not included and should be inspected or replaced separately. Proper torque specifications should be followed when mounting the rotor to avoid warping.
