Brembo 09.C651.11 UV Coated Front Brake Rotor for 2014-2018 Mazda3/2016-2021 CX-

Vehicle Fitment

• 2014-2018 Mazda3 (BM/BN), Sport / Touring / Grand Touring / i Sport / i Touring / s Sport, 2.0L SKYACTIV-G I4, FWD - without Electric Park Brake (Mexico-built & Japan-built)
• 2016-2021 Mazda CX-3 (DK), Sport / Touring / Grand Touring, 2.0L SKYACTIV-G I4, FWD (2WD) only

Fitment Notes

• Fits front axle only - sold as one (1) rotor per unit; purchase two for a complete front axle replacement.
• Compatible with Mazda OE part number B45A33251A.
• This rotor fits models equipped with a 280mm (11.02 in) front disc. Mazda3 and CX-3 variants with 295mm front rotors require a different part (09.C652.11) - verify your front rotor diameter before ordering.
• The Mazda3 fitment applies to the 2.0L engine only. 2.5L Mazda3 models use a 295mm front rotor and are not compatible with this part.
• Does not fit CX-3 AWD (i-ACTIV) models or any Mazda3 equipped with an Electric Park Brake - confirm drivetrain and brake configuration via VIN before purchasing.

Features

• Pillar Venting Technology (PVT) increases airflow through the rotor, improving resistance to thermal cracking by over 40% versus conventional vane designs.
• Full UV coating across all rotor surfaces - including internal ventilation chambers - provides superior corrosion resistance ready to install straight from the box.
• High-carbon cast iron construction minimizes noise and vibration for a smooth, confident braking experience in everyday driving.
• Precision-machined to Brembo's strict dimensional tolerance values, minimizing lateral runout and delivering consistent pedal response.
• Direct OE-equivalent replacement - meets or exceeds Mazda factory specifications with no modifications required.
• ECE-R90 certified, meeting strict European safety and quality standards for replacement brake discs.
• Part number and minimum thickness stamped directly on the rotor for quick service identification.
• All required fixing hardware included for straightforward installation.

Product Description

The Brembo 09.C651.11 is a UV-coated, Pillar-Vented 280mm front brake rotor engineered as a direct OE replacement for the 2014-2018 Mazda3 (2.0L FWD) and the 2016-2021 Mazda CX-3 FWD. Built to Mazda's factory specification B45A33251A, this rotor installs without modification and restores full OE braking performance. Brembo's PRIME line delivers the same engineering rigor applied to its OEM supply contracts, ensuring precise dimensional fit and reliable stopping power.

Full UV coating across the entire disc - including the internal ventilation channels - prevents pre-installation corrosion and maintains a clean appearance throughout service life. Brembo's Pillar Venting Technology improves heat management over conventional vaned designs, delivering consistent performance through the stop-and-go demands of daily commuting. Always confirm your vehicle's front rotor diameter (280mm) and drivetrain (FWD) before ordering, as the 2.5L Mazda3, AWD CX-3, and Electric Park Brake variants use different rotor specifications.
