Product Details

The DFC Brake Rotor - Drilled and Slotted - Silver line is built for drivers who want a direct-fit replacement rotor with a performance-oriented surface design. This rotor uses a directional slotted and drilled braking surface to help manage heat and maintain stable contact between the pad and rotor face. The zinc silver hat finish and rust resistant coating add protection against corrosion, while the vented design supports heat dissipation during stop-and-go use.

Compatible With Mazda CX-3 front left applications from 2016-2024, and Mazda 3 front left applications for 2014-2016 and 2017-2018 model years with the listed build restrictions. It also fits Mazda 3 Sport front left applications for 2014-2016 and 2017-2018 model years with the listed build restrictions. Part number 631-80053L is a fitment-specific rotor for these Mazda brake service needs.

Common Issues This Rotor Can Address

• Brake pulsation from a worn or uneven rotor surface
• Reduced braking consistency from heat buildup
• Corrosion on the rotor hat or exposed surfaces
• Noise or uneven pad contact caused by rotor wear
• Service replacement needs for front left Mazda brake repair

Installation Notes and Tips

Verify rotor dimensions, bolt pattern, and hub measurements before installation. This rotor is directional, so confirm the correct orientation during service. Fitment includes Mazda 3 and Mazda 3 Sport models built in Japan or Mexico for the listed years, excluding vehicles with Electric Parking Brake where noted. Always inspect pads, caliper hardware, and hub condition before completing brake service.
