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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide improved heat dissipation and consistent braking performance. The combination of cross-drilled holes and precision slots helps reduce brake fade by allowing gases and debris to escape, while the solid rotor design offers durability. This product line is suitable for drivers seeking enhanced braking response on Mazda 3 and Mazda 3 Sport vehicles without requiring vented rotors.

Technical Specifications and Features

This disc brake rotor features a solid construction with an overall height of 40.9 mm (1.610 in) and a center hole diameter of 71.7 mm (2.823 in). The rotor includes five stud/lug holes, each measuring 13.7 mm (0.539 in) in diameter, arranged on a 114.3 mm (4.5 in) bolt circle. The coated hat finish protects against corrosion, extending the rotor's service life. The floating disc mounting system allows for slight movement to reduce stress and improve rotor longevity. Note that this rotor does not include an ABS tone ring or bearings.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Mazda 3 and Mazda 3 Sport
• Improves heat dissipation to reduce brake fade during spirited driving
• Addresses brake noise and vibration issues caused by uneven rotor surfaces
• Enhances braking consistency under heavy load or repeated stops
• Prevents corrosion-related rotor damage with coated hat finish

Installation Notes and Tips

• Ensure compatibility with Mazda 3 or Mazda 3 Sport before installation
• Check rotor thickness and discard limits (nominal thickness 11.000 mm, discard thickness 9.000 mm)
• Use proper torque specifications for the 5 lug nuts on the 114.3 mm bolt circle
• Inspect brake pads and hardware during rotor replacement for optimal performance
• Verify absence of ABS tone ring compatibility as this rotor does not include one
