Installation Notes and Tips

Verify rear axle fitment by year, model, and brake sensor requirement before ordering. Some applications require sensor BPS-31067, while 2015-2016 BMW M4 rear fitment requires sensor BPS-31074. Confirm rotor condition and inspect caliper hardware, guide pins, and brake fluid level during service. For accurate ordering, match the vehicle to the listed rear fitment and reference 2551-1656-00.
