This product line features vented rotors with a coated hat finish to resist corrosion, making them suitable for both street and light track applications.

Technical Specifications and Features

This disc brake rotor features a vented design with straight vanes to optimize airflow and cooling. The rotor’s overall height measures 2.028 inches (51.500 mm), and it includes a floating disc mounting system to accommodate thermal expansion and reduce stress on the braking components. The center hole diameter is 2.677 inches (68.000 mm), and the mounting bolt hole circle diameter is 4.5 inches (114.300 mm) with five lug holes sized at 0.512 inches (13.000 mm). The rotor weighs approximately 18.1 lbs (8.22 kgs), balancing durability and performance.

Applications and Problem Solving

• Improves brake cooling to reduce fade during aggressive driving
• Enhances stopping power for Mazda 6 and CX-5 vehicles
• Prevents rotor warping caused by excessive heat buildup
• Resists corrosion with coated hat finish for longer service life
• Maintains consistent brake pedal feel under heavy braking conditions

Installation Notes and Tips

Ensure compatibility with your specific Mazda 6 or CX-5 model before installation. The rotor does not include bearings or ABS tone rings, so verify if your vehicle requires these components separately. Proper torque specifications should be followed when mounting the rotor using the 5 lug holes. It is recommended to replace brake pads simultaneously to optimize braking performance and rotor longevity.
