Detailed Product Description

This disc brake rotor is specifically designed for Mazda 3, Mazda 3 Sport, and Mazda CX-3 models requiring a 280 mm outside diameter rotor with a 5-lug bolt pattern (114.3 mm bolt circle diameter). The vented design allows air to flow between the rotor surfaces, improving cooling during braking. The drilled and slotted surface helps evacuate gases and debris, maintaining consistent pad contact and reducing the risk of brake fade. The rotor’s nominal thickness is 25 mm, with a discard thickness of 23 mm, ensuring safe replacement intervals. The Geospec silver grey hat finish and rust resistant coating protect against corrosion, extending the rotor’s service life.

Common Applications and Issues Addressed

• Replacement for worn or warped rotors on Mazda 3 and CX-3 models
• Improves heat dissipation to reduce brake fade during heavy braking
• Helps prevent brake pad glazing and uneven wear
• Addresses rotor corrosion and surface rust issues
• Enhances braking performance in wet or demanding driving conditions

Installation Notes and Tips

Ensure the rotor is compatible with your specific Mazda 3, 3 Sport, or CX-3 model year and trim. Clean the hub surface before installation to prevent runout. Torque lug nuts to manufacturer specifications and inspect brake pads for wear when replacing rotors. Directional rotors must be installed with the correct rotation direction for optimal performance.
