Important usage & fitment notes:

• Always verify fitment by your VIN, model year, engine and brake system version (e.g., sport pack or standard) because pad shapes and material can vary.

• Given this is the front axle set, wear may be heavier at front so replacing both sides in the axle together is common practice.

• When installing, ensure you inspect the rotor/disc for wear and thickness, correct bedding‑in of new pads, and proper hardware (springs, anti‑rattle clips, wear sensor if included).

• The weight figure (~2 kg) gives an indication for shipping or parts inventory but always check actual packaging/brand variant.
